Just took your advice and in less than 5 min all the rust was gone. My tank wasn't that bad but holy crap this stuff works! No dilution just make sure you have baking soda diluted with some water on hand in case you get some on your self you can neutralize it. I used an empty 2 liter bottle of soda with water about a 1/4 cup of baking soda mixed in.

you are a freaking genius! Solved my tank issues after 10 minutes with just watching this video. We have been so conditioned to just go the "purchase a solution" route that I have actually spent quite a bit of money, probably hundreds throughout the years on "rust reformers" and "tank liners" and this shit works just fine. You just saved me a crap load of money. Thanks for posting this buddy.

Did the rust come back?

Years later still is a great how to. Just got done with a KLR tank, perhaps fifteen minutes total sloshing a gallon around in that big tank and it now looks new. Rinsed with water to dilute the acid, then rinsed with Baking Soda solution to make sure it was neutralized, drained as best I could, and then WD40 in their "Big Blast" can which is seemingly made for the purpose. After sloshing the WD40 around for a while what drained was a milky liquid that I'm thinking is the remaining water emulsified by the WD40, I suspect not much water left to worry about. Then poured in a half of a quart bottle of Marvel Mystery Oil and sloshed that around...hopefully no flash rust as it will be a few days before I can fill the tank with gas. THANKS, RM!

instant gratification...i came to the right place

I just did this on a 1964 chevy van gas tank. The van was last registered 1983. I pulled it out of a field where it was buried up to the axles in mud. The tank was disgusting -- full of scale and nasty rust. I actually poured chunks and flakes of dried rust out of the tank. I used straight muriatic acid like in the video. I let it sit in there about half hour and sloshed it around every now and then. It got it clean! You can look in there and see clean metal, where previously it was all scaly nasty rust and crud. I was amazed. It really worked well. Thanks alot for the video. Very helpful.

I tell you I had no time to wait for all the "products" to clean out tanks that take anywhere from hours to days... I had one day & this worked better than I could of ever hoped for! I wish I would have taken a video of it. i wasn't even going to worry about the outside of the tank but this worked so well & was so easy I did the outside of the tank as well!! the before & after photos are almost non believable.

Bro! Thanks for the info! Tried this on my rusty gas tank and it worked flawlessly! When you shook my tank, it sounded like a salt shaker! That's how bad mine was. Now it's like a new tank! Thanks again.

Muriatic Acid is the KING! Been trying to tell people for years!........my personal favorite is Naval Jelly, good balance of Power and slower burn rate(maybe 1 or 2 hours)....good for thinner, or higher end tanks, No risk of burning holes.....also leaves Lots of chalky Residue, so won't flash rust...and it stops eating once you drain water! Great stuff also.

Hi, random mechanic is that a batavus? My dad and me had long time ago a Horex and he cleaned his tank , someway like yours. Only he used small grind ftom the garden and gaz, My job was to shake the tank and ik worked! Nice to see someone not using fancy stuff but American brain.

Great video, thanks for posting it. My tank is larger and more awkwardly shaped, the motorbike started to have poor performance I found water in the fuel filter, I suspected it was from the gas station, we just had hurricane Ian come through, I replaced the gas, it worked fine for the five minutes and went back to starving, I changed the filter, same thing. I ran it without the filter, same thing, I cleaned the carbs, ran okay for 5 minute and started to starve again. When looking through the gas we noticed a spot of rust in one of the bends at the bottom of the tank, it was not big at all. I did the vinegar clean first, tons of rust came out along with flakes, it looked like someone crushed a cigarette inside, also some mold looking stuff that was at the top inside of the tank, it came loose because i filled the entire tank with vinegar. after removing the vinegar i rinsed it with baking soda and water, then water along, then i dried it with the heat gun. It was all rusty worst than before. That was when i came across this video. I watched it, I read all the comments. I got me a gallon of muriatic acid, plugged up holes with rubber and makeshift caps that i made, I put the acid in, shook the tank, got a timer, turned it as needed. Then I dumped the acid, immediately dumped inside a 1/2 a gallon of gas (from a different gas station) mixed with 10w40 synthetic oil, shook the tank around all possible ways and got rid of the gas, which came out black, I repeated this rinse one more time. I reinstalled the float with sensor and petcock, added about 2 gallons of new premium gas, fired up the thing. it sucked so bad, worse than before. I disconnected the tank and run it on gas from a separate container, it ran better. The inside of the tank was completely rusted, even worse than the first time it flashed. I had done some rusty tools that i had around, used the same process, they are okay, no rust on them. Even with the humidity brought by the next storm, Nicole. Now I have 2 gallons of muriatic acid diluted in 3 gallons of water, my tank hold 5 gallons, it is filled to the top, I figure that the last time as I was turning it I must to have missed a side. it already removed the rust that was on the tanks cap hole neck. What do you recommend, I do different this time, after I remove the acid wash?

This is awesome, thank you so much, just what I was looking for a way to fix my tank fast.

OK you safety guys out there, YES you should wear safety equipment. Secondly, if you let air into anything that is "clean metal", it is going to rust. This video is great and I beleive intended to clean a tank that will be used very soon. The oil coating he puts in will slow down the corrosion process but will not stop it. I have filled mine with ETHANOL FREE GAS after cleaning the way this gentleman states and have HAD NO PROBLEMS !!!. Also I would recommend (no I don't have any investment in this product) using Yamaha Ring Free in all your engines. Check it out on You Tube. I have had amazing results. No I don't work for any associated companies wit this product .... It just works. Keep the air out of those tanks and they won't rust. Thank you again for this helpful video.

Dry wall screws are pretty dang sharp - on an older, heavily rusted tank, I would be leary about using them for fear of them poking a hole in the tank when shaking them around.

I just tried this and it worked very well for my needs. Before the acid I filled the tank with drywall screws and made each of my 3 kids take turns shaking it for 5 minutes to break up the rust first. I then flushed it out with distilled water and added some gas mixed with oil to hopefully help coat the surface from rusting again. All in all it worked very well, thanks for the video!

I tried this cleaning technique on a really nasty rusty Harley-Davidson Sportster fuel tank, I filled it to the brim with the acid, I actually had to let it sit for four days before all the rust was dissolved, that’s how bad it was. However the result was spectacular! My advice is to siphon all the acid back into its original plastic jug with a cheap plastic siphon then flush with a garden hose. Just coating the inside with oil won’t prevent rust from returning. I recommend following up with a tank liner product immediately! Then your good to go. Word of caution: you need a good respirator because the fumes carry out to about a 15 foot radius. Also, you need good wrap around eye protection goggles and rubber gloves plus your garden hose handy! The reason why I used a siphon was to protect the paint job on the fuel tank and it’s much safer and cleaner transferring the acid back into the original container. Of course all of this is done OUTDOORS! Away from kids or critters.

Tank liners are a joke and don't last long, chip off and are harder to remove than rust. Just add a half ounce of 2 stroke oil every few tankfulls and you wont have a rust problem.

Thanks man i have project bike im going to try this on

I'm restoring an old Honda and had some hydrochloric acid in my shed. I just tried this process with a 40yo Honda tank and it cleaned up 99.9% of the rust within 20mins. I'll leave it to sit another 30mins and it will probably dissolve the rest to look perfect. It did however expose two pin holes which I'll lead solder. Use both sides of your brain, be careful, wear gloves and don't drink the stuff.

You absolutely do not want to breathe any of the fumes from this thing. Or get any of the smoke from it in your eyes.

Good stuff man, I'm going to try it if I can find any place that sells it.

Nicely done!

Just bought an ‘80 Garelli and I’m gonna do this on Monday.

Hello, the bottle of acid I have reads 20 degrees baume commercial [31.45%]. On the bottle it says to dilute acid with 4 parts water to remove rust from steel, followed by a thorough water rinse. What are your thoughts on diluting? It seems that you were using undiluted from the bottle but maybe your acid was not as concentrated as mine. I have approx 2 cups of acid in a very old bottle. Given the fact that you left it in a very short time in the tank maybe undiluted followed by a flush is the way to go. Also, I have an old kitchen scrub brush (pole style with metal stem and plastic brushes) which is near the end of its life cycle so I am using that to loosen/remove rust as much as possible before trying acid. I also am using a narrow beam flashlight to see down into the tank. That way I can see the before and after. Many thanks, David.

This worked perfectly. Mine ended up nearly spotless. All I did was tip the tank around to wash it in acid.

I’ve got to try this! I have an old 1958 David Bradley Roto Spader with a Briggs model 8B engine and the tank looks like it’s had old gas left in it for 60 yrs. Full of rust and the usual suspects. I tried vinegar and added some nuts and bolts to shake it around and got a lot of the chunks and rust out, but it takes too long and I can’t shake the thing for hours to get it done. A paint shaker would be great though. There’s still a lot of “surface” rust in the tank and it’s gotta go! Hope this does the trick because I’m ready to put this thing back together and see if it’ll run after it appears it’s not ran in at least 20 yrs!

Hi, I have a Harley 2 piece gas tank that is partially rusted inside. I shook loose the stuff that was jingling around inside and see that one of the half tank has substantial rust. The material which fell out was like a very thin film, almost like jelatine. I know these gas tanks come coated inside with some kinda material. I am worried perhaps the muriatic acid may destroy the rest of the lining? Any comments? Seems your process is fantastic way of cleaning out the tanks, just not sure if it can apply for me in this case. Cheers, Greg . . .

Just wanted to give an update on my old Briggs and Stratton fuel tank, I used the stuff from Walmart which is weaker and I went 50/50 and soaked it for about 3 1/2 hours and it worked great. Thanks for this video.

I've got an old Jeep Gladiator pickup truck that has been sitting for a long time. I'm going to clean out the gas tank using one fo these methods but do I need to be worried about anything in my gas lines? I really don't want to screw up this motor.

I've used acid before to clean out my 1947 Ford 2N"s tank, it works quite well. But, first things first, safety equipment is a must. Chemical gloves, eye protection and preferably a respirator. Not using safety equipment is asking for it... Also if you have really bad deposits in your tank like some of mine, I recommend using bolts, nuts etc. to remove the big junk first. Then once that is done use the acid to remove the rest.

I used aquarium gravel in gas and shook it for quite a while. All the flakey and a lot of visible rust was removed. I figured Muratic Acid was the answer as I used it in my swimming pool. If you buy it in the pool section the charge you $20 for a gallon as folks with pools probably have too much money. Go the paint department and the same Muriatic Acid is a few bucks. Sure, rubber gloves are smart and goggles not a bad idea.

POR-15 or Kreem. I had a tank Kreem'd many years ago and it was fine the rest of the time I owned the bike. I am working on an old bike for a friend and I will be using this method and then POR-15 in the tank.

Kawasaki Vulcan he says in the video after cleaning the tank put oil in it then dump it out. I've been told the same thing to a mower tank I got.

nice - I just got a Honda ATC 185S - and the tank is a horrorshow inside! Would you recommend doing a bit of a shake-around with gravel/old bolts first, to remove the biggest flakes?

the acid should eat all of it off but it might help to knock some of the crud loose and dump out what you can just so the acid isnt having to eat through layers of crud it would definitely help cut down to cleaning time .

I cleaned my tiller gas tank with that acid, but I have a same problem t in a month, do you know what happened?

You can order it off E Bay, Muriatic Acid.

Gonna try it on my '72 SL 100 can't stop the rust I may coat it after

Wonder what the acid % was? I have been trying to get Lime Away to work, but it's not strong enough. It has sulfamic acid in it.

So...what about neutralizing the metal w/a mixture of baking soda and water prior to oiling (diesel fuel works good) and then rinsing w/gasoline. Not necessary?

That works too , i just didnt have any baking soda , rinsing with 2 cycle mixed gas works equally as well

how much oil do I put in the gas tank I have a 6.5 gallon tank needs cleaned out and can I leave the petcock on

@TheRandomMechanic

i would skip the water and oil step , i now rinse the tanks with 2 stroke gas , works alot better , if the petcock is aluminum you have to take it off or it will dissolve

Works Great thank you

I got a rust so bad in my 73's honda CB 450 tank, it caused a leak. I just cleaned it and seal it with metal resin from the outside of the tank. Will the acid messed up the seal I just made? Thank you

it shouldn't but if it does you could always just seal it again

how long do you leave the oil in for or do you just coat the tank and add gas after that ?

+Mike Traspena i just normally just coat the tank and pour it out then ad gas if i intend on using it right away if i am cleaning it and putting it on the shelf to use later il leave the oil in it

Once you get the rust out you MUST install a liner like Red Kote or the rust comes back instantly.Call a local radiator shop. Many will boil out your tank and install a permanent liner for around 25.00.Money well spent.

Tank liners dont last long and must be removed and that is 10 times harder than rust to remove.

hey man, any recommendations for the rubber plug-in where the petcock/fuel valve usually goes?

@TheRandomMechanic

usually i just run up to the hardware store like ace hardware and look at what types of plugs they have or if i dont feel like going i will take a piece of fuel line that fits tightly in the hole in the tank and jam a bolt in it

Great vid. How do you you get rid of all the cruddy acid afterwards?

@TheRandomMechanic

5 жыл бұрын

the acid is for cleaning swimming pools and driveways , you can find a spot out in the driveway to pour it out and hose it down to neutralize it , or you can just dump some baking soda in it to neutralize it and toss it in the trash

Good to know. Also, if it does flash rust would I have to do the whole process all over again?@@TheRandomMechanic
