Granted, I do not even. For me, the wetting agent is in the cleaning solution for telescope mirrors. There is the best and safest, but also the most expensive choice. It is important that the cleaning takes place without dripping. This creates detergent per se, but I do not trust the recipes, since the producers think Rinse is a kind hand cosmetics. Moisturizing substances would in any case be fatal, and as for perfumes, I do not know what do with the highly reflective coatings. The recipe: a shot of pure wetting agents in double distilled water, about 20% pure isopropanol to. Could not be better.
