The thin, fragile aluminized coating is on the very top-most surface--makers electro-deposit aluminium in a vacuum chamber only onto the very top-most surface of their thick glass mirror blank (the ground and polished spheric or parabolic surface). I'm extremely encouraged that you removed the mould so easily--thank you, great to see! However, this is not the optician recommended process used by most of us for cleaning coated surfaces. eg: I won't go through what's recommended, suffice to say, I saw no preliminary attempts to brush and blow abrasive debris off the aluminium surface before back-and-forth rubbing (abrasion/ grinding) began at 3:22. On a related issue--mould evolves millions of spores--just waiting to recreate this same issue all over. In your environment, have you noticed any recurrence?

I can't believe how easily you did I hope when I do exactly what you did to yours to mine it comes out that nice also nice presentation thank you

I also have an Astromaster 130EQ, and I'm still afraid to clean the mirror😅 does using wipes not damage the aluminum coating of the mirror sir?

Don't worry, if u watch carefully then u can see that the mirror is very thick. There's no way u can reach the coating while cleaning 🙏

@ngurah_usa You are right in your caution and concern re potential damage of coatings. Since 1985, most quality mirrors have used anti-refection coatings (only a matter of a few wavelengths of light in thickness) applied on top of the thin, reflective aluminised surface. Without appropriate training the risk of damage does exist.

Thank you for the cleaning instructions.

Can use water to clean

Yes, Just Distilled water and avoid using hard tap water. And a bit of lens cleaner for dslrs and slr cameras for killing the molds and a UV disinfectant lamp kills the spores including microbes that damage your lens coating.

Use a mix of water and rubbing alcohol. That's what is in the official user manual

@@Fiercefighter2 Use a mix of distilled or deionised water and technical grade isopropanol (not so-called 'rubbing alcohol' from a pharmacy), with a drop of clean liquid household detergent. Off the top of my head, a ratio of 60:40 distilled water to iso propyl alcohol should be great--look it up though.

You, and I, are not surprised... However, it was a great demonstration of the apparent ease with which mould can be removed from an astronomical mirror, without leaving obvious permanent damage to the mirror surface, caused only by the organism.
