I was talking to a fellow power washer and he said he tried olympic mildew check mixed with bleach with good results.

Anyone try mildew check?

Looks like an overpriced marketing scam, kind of like Jomax.

I've tried Jomax, and it doesn't do much.

I've never tried it Mike. I normally just stick to the basic chems for all my cleanings. I'm kinda like the old---If it ain't broke don't fix it , kinda guy!

Here is the MSDS Link http://www.pittsburghpaints.com/our_products/stains/mildew_check_multi_purpose_wash/index.htm

It has alcohol in it, and some benzene.

Stick with Apple Cider, LOL

I see, 5% alcohol...whoopie!! Talk about a rip-off, jeez.

There MAY be more going on ?
Not familiar with the other stuff in there ?

I think it's suppose to leave a coating behind that inhibits mildew - I tried it on one home and it didnt work.
