As a contractor I have to find something that works in some extreme circumstances. I have tried them all. Mold Armor 30 Second Jomax Zep and every other oddball brand of that makes extravagant promises on the label. And I keep returning to this Clorox product because hands-down it's the best.

Clotox Outdoor bleach is the best i have used to get rid of green algae and the really tough black algae that griws on expised concrete in Florida. I ysed a roller at first and it killed the green algae easily but i had to use a stiff brudh on a broom to scrub the bleech into the black crud. It even took a second application an s few spots since it had been there for a couple if years. It did a great job!! I am very satisifed with the tesults. I tried others and this worked the best. Give it a shot. Its not expensive. See picture of before and after

Used this on the north side of my house to remove the mold on my siding....each time it has removed all of the mold. Love this product! I wish they still made the bottle that connects to the hose. That made it so much easier! This is seriously the best product for my siding mold!

Pros Easy to Use, High Quality, Looks Great

My go to product for several cleaning jobs outside the home. I use this product for cleaning the driveway and sidewalks around my property. As well as cleaning the vinyl siding and the roof.....I have several trees around my home and clean up which is an ongoing job. I need a product that lasts as well as works and this fits the bill for me. It comes concentrated so it can be diluted to the strength you need depending on the job at hand. I also use the product in my drains in the home as well as my AC drain.

This stuff will cut mold and mildew from house siding in a heartbeat. I use it in a 1 gallon portable tank sprayer though and not in my pressure washer. Then use either a strong stream direct from the hose, or a rinse stream from the pressure washer to rinse. Works great.
