Best For pet: Wet Forget deck wash

Buy on Amazon

Not everyone likes to purchase wash for their regular usage, but the wet forget deck wash would be an anomoly. It is a must for mold and alge. It does not rain inside, so you would see no removal of existing mold and stains with this product. The concrete telescope pad is nearly white on the treated half, and still ugly, stained and dark-looking on the other half. A light bleach solution and/or simple soap and water and proper drying are a much safer indoor alternative.

The real shocker is how well it cleaned off the stone pavers. It is supposed to be non-toxic to plants. They also encourage you to reapply as you want this stuff working for you throughout the rest of the year. It doesn't have a strong smell.
