Citric acid to clean latex mask

Hello, I was wondering the ratio between warm water and citric acid to clean a mask. I read it online before but can't remember where. I think it's a teaspoon acid to a cup of warm water, but not sure.
 
I've only done it with ammonia, but it should be the same. It's non critical. Bucket of water with a splash of chemical.
 
If you're using it to promote adhesion of new latex, the ratio isn't too crucial. Just keep it fairly thin and water-y.
What works for me? I apply with a brush and give it a good scrub and then apply it again letting it sit for a few minutes. Wash it off very thoroughly and apply the new latex. You should get a perfect bond. This only really works in small holes and gaps and in thin applications. Larger holes may be better suited to fill with propatch.

I realize some people like using products such as citric acid, harsh solvents, vinegar, etc. and believe it will increase paint adhesion. I've personally found that to not be the case, especially with stuff like Rubber Cement paints as they already chemically bite into the surface of the latex. In fact, if you apply something like citric acid and leave it on the cast before painting it can actually CAUSE delamination.

A good wash with warm soapy water is definitely all you need in my opinion. The less time spent handling chemicals the better IMO.


Again though, I stress this being all my opinion, and how I personally go about the stuff. YMMV certainly.. But I doubt by much. :)
