There are molds and stains on my deck that I wanted to remove, so bought this product called 30 second cleaner. I think it's a scam, lol, cause first, it needs more than 30 seconds (around 5 minutes). Second, what are 30 seconds outdoor cleaner ingredients? is it just bleach? Well, it contains 5% Sodium Hypochlorite and 93% H2O. There are also 1.2% Proprietary ingredients, which idk what that is. Does anyone know what that is?
