Pablo, bleach did nothing on the mold in the stucco on my house... I tried it several times... now you being a vendor of boutique oil products will have heard me say I am not the type of people who buy expensive stuff when the regular cheap stuff works just as good, so when I tell you bleach wont work on everything but Wet and Forget does, trust me as I don't spend extra money on more expensive methods until the regular household laying around stuff does not work.... and the stuff I recommended is relatively cheap when compared to the results and how much faster the cleaning process becomes with it's use....
on top of that that 30 second cleaner I also recommended turns pressure washing a house from an all day affair to an hour or two. worth saying I pressure wash my house 2 or 3 times a year...
but Wet and Forget is good stuff, but it is a treatment with enzymes in it... and you wont see results the first day, you will see them a month later.... as well as the 30 second cleaner... that stuff kicks butt and is maybe 12 dollars a gallon.
