Its not just sun damaged its oxidation from the air. I have pieces that have never seen sun light and stored in the basement for 30 years that turned yellow. Some pieces just oxidize quicker than others. also you need to make sure the pieces are all exposed to the sun with a shallow container, and let them sit for 3 hours in the sun, and check every hour, and flip them. I've been successful with white, gray, and blue with this process.

This is fantastic! Thanks for uploading! :D

Hey, this worked perfectly for me. I found it was helpful to do the process in a disposable metal oven dish. I am really pleased that it has worked so well as it was going to take me ages to replace a selection of 100+ white pieces that had gone a horrible tan color. This worked well, even for my severely yellowed pieces. It was complete after approximately x2 8-hour days in the sun at ~25 degrees C.

Good afternoon Alex, thank you for the tip. Best regards from a Portuguese guy living in Jersey.

How do these bricks look now. Just Saw An other video stating the decoloring Comes back worse after a few months.

So, it doesn't damage stickers, but what about white pieces that have printed things on? (I'm specifically thinking of the flags on the Saturn V)

Good stuff, definitely have a couple sets with plenty yellowing. So does it work on the colored brick if you stay indoors?

so you can do stickers and printed part's? also i saw another guy do this but he also only put them in the sun for five hours and put gray ones in the sun

Hi, Does it matter on the temperature of the day? is winter sun as good as summer?

Hi, So for the grey parts, I should leave them on the peroxyde with NO sun then? I have two of those huge 90's castles all gone grey-yellow :(. Thanks!

Cool , I did a similar process but in a low strength jell form brushed on for some of my model trains and retro consoles...

Awesome technique. As I was working on my Lego airport, I noticed some of my white bricks were looking a bit yellow. Now I know what to do. I was thinking maybe soak them in vinegar, but that might actually damage them more than the hydrogen peroxide would.

Does this work on printed pieces as well? I have some clone troopers that could really use some whitening

thank you so much man! :D

I just brought a load of white bricks off eBay and 50% of them are discoloured! (No wonder they were cheap) I will use this technique, problem is I live in Britain and it’s always cloudy, who knows when the sun will come out. Thank you for your tip.

I do this sometimes with the old grey ones. In that case it put grey ones together with discolored white ones and check the results on a daily basis. When I see that the hydrogen peroxide has done its job with the whites, I put them all out. Cannot say that this does not result in some excess bleaching of the grey ones; it probably dies. But for me the result is fine.

Question: does each piece have to be in direct contact with the sun? Like if I put 50 pieces out and some are submerged under other pieces, will it still work for those pieces? And will the undersides of the pieces be fixed or do I need to be continually stirring the pieces up?

I'm putting in all my bricks(except black) from my Lego 7727,7730, and 7760, even the ones that don't look discolored, to make sure none aren't yellowed, but would that mess them up? Thanks

Some of them do turn yellow again, but it takes a few years. You can just do the hydrogen peroxide process again if it happens. I did a batch a year ago and most of them are still almost as white as new. The main exception is a big ship piece that was horribly yellowed prior to treatment and probably should have gone longer. It is still leagues better than it was before, though. I don’t know much about how the process affects brittleness, but I think brittle parts is a problem with older Lego in general.

can you use UV lights instead of the sun?

Hey Alex, I have a few things to say/ask. 1: Nice video! 2: What did you do with that leftover Hydrogen Peroxide? (The one in the cup after some of it evaporated) Can you like use that again on different bricks and add just a little bit of Hydrogen Peroxide or do you have to remove the whole substance and fill it again (because by my calculations you could almost fill two cups if you kept throwing it away) 3: Would any Hydrogen Peroxide work or does a specific type of Hydrogen Peroxide work? (They're all the same but the concentration is a little different) Thank you! The one I found is called "Heritage Products Hydrogen Peroxide Mouthwash" Not sure if that will work but I don't want to take the risk because it is kind of expensive in my country. I need to revive some of my white bricks xD

Excellent video! One question, I was under the impression that the bricks needed the sun exposure (with the HP), in order for it to work. Your bricks seem so packed in there, they are obviously not all getting direct exposure. Is it a chemical reaction with the sun and the HP that then reacts on the brick surface? I hope I'm explaining it well. I would love to pack as many bricks in as I can, but I didn't think that would work.

This solution will actually not only make your lego bricks look better but it will also prevent your bricks from becoming brittle. Plastics with bromine will yellow over time when it comes into contact with UV Light (not only from the sun but also florescent lights too). The yellowing is essentially a chemical reaction to UV Light. This chemical reaction makes plastic more brittle over time in addition to it yellowing. The solution in this video reverses that chemical reaction. It is however not permanent. If your lego is in a room with a lot of direct sunlight or florescent lights, it will yellow again over time. People also use this same solution for other plastics such as those found on electronics equipment.

Question: does this method damage the print on a lego piece.

I did some research on this, and there's another product called retr0bright which also uses hydrogen peroxide as the main ingredient, however it also uses an oxiclean product, xanthan gum, and glycerin. It is designed for this exact same process however it also works on grey. I read on a lego blog that someone tried using just hydrogen peroxide for 24 hours and it didn't have effect on their parts (they did not specify what color). Does the hydrogen peroxide bring your white bricks to the same color as if it is new? Or is it still slightly damaged. Also, what's the shortest amount of time that you did this and the bricks were fully restored? I would appreciate very much if you could reply.

Don't try this with yellow bricks. They will become light yellow or beige. :D If the sun does not shine for a while, heat helps too. Simply place the container with hydrogen peroxide and Lego Bricks on a radiator/heater. After a few days the bricks are nice and white again. A closed container works better than an open one because of the atmosphere that forms in the container.

I have a grow light which is UV and used that inside and worked much faster as there was no night.
