Zinsser Jomax 60101 House Cleaner and Mildew Remover, 1 Gallon - Home Siding Cleaner Concentrate - Safe for Outdoors

This product makes a great difference. When using bleach alone the final results is much less than when adding Jomax. I have used it in the shower as well as on the deck and the difference is notable. After pressure washing the deck, I sprayed with the jomax/bleach solution and the mold and mildew is gone and shows no sign of returning. The deck is ready for the stain.

This product does what it says. Really good cleaning power

I heard about this product on quite a few Home Improvement podcast so I decided to give it a try. I had tried the soap and bleach method before as you do it yourself for would normally like to try to do. Well I had results I had to do a lot of scrubbing and the bleach risk getting in the eyes are on plants and possibly killing them we're not something that I wanted to really deal with. I wanted something that would work with ease something I could spray on and then just rinse off. This was definitely the product for that all you have to do is get a sprayer put some in at the right deletion rate spray it on wait a little bit come back spray it off and 80% of the time it just takes one application. You may want to do a second application or there may be really hard set areas that may require a little bit of a brush but most of what you spray will definitely rinse right off with the surface clean and Clear of any Grime mold or mildew. Highly recommend this product definitely worth the price even though it's a little pricey it'll save you lots of time and labor.

This works so well. Mix according to directions, spray liberally, wait 5 minutes, and you're done. Used on my fence, aluminum patio roof and roof soffits. Such a good product and value. No scrubbing necessary.

Easy to use and no need to hire someone to power wash house once a year. And allows touch up during seasons

I've been using this product for several years to annually clean my houses' soffits, fascia & gutters. It does a nice job.

Use it every two years recommend it mix with bleach and water mold comes off I use pressure washer if used every 1-2 years pressure washer is optional ps also need a sprayer

Sprayed mixture of Jonas an Clorox on house with smart siding. Left on for about 10 minutes and sprayed off! Paint job looks freshly painted with no mildew!
