Zinsser 60104 Jomax House Cleaner and Mildew Killer, 1 Quart

Great product

This stuff really works! You don't even need a power washer ...just mix it up, then spray the green stuff ..let it sit about a minute and then use your garden hose to spray it off. On tougher spots you might have to spray again and let it sit a little longer, but it is amazing stuff! I've used this several times on several houses and it doesn't disappoint, Used on siding, walkways, stone paths ...it all works and doesn't seem to bother the plants and grass. You just can't be this stuff!!!

This is a great product and it works wonderfully

I was very unsure at the time of use but I followed the instructions and after a couple of days went back to look and the area I cleaned looks brand new.

Best thing for vinyl siding

i bleach it activates bleach to higher level. Not sure how it works but it works!

very good product.I use it every year on my house

Works great when you read the directions. Works great to remove algae from vinyl siding and reduces need to get on a ladder since it's an easy rinse with hose pressure.
