Does this have to be used in a pressure washer?

I have a garden hose attachment bottle that can be filled with a cleaner concentrate, and it will dilute the cleaner as it sprays. Will this product be effective in that type of sprayer?

No. On my porch I used it in a garden sprayer to get into tight places and it worked well,

Can I put this in a bucket and use a scrub brush to clean my siding?

I saw that using a pressure washer is recommended but can I just brush this on with a siding brush and get some decent results? I just need to clean the house good enough to satisfy the home owner's association and I cannot afford to buy a pressure washer. Also, even if I could afford one, I'm afraid to use a pressure washer as I have heard using one (if you don't know what you're doing, which I don't) can force water under the siding. I'm not asking for a guarantee, I'm just asking if I can use this product in a bucket without damaging my siding.
Asked by: nessun
A little dated but this might help someone else? Sure you can, just follow the dilution recommendations. Wet the siding first, then start at the BOTTOM of the house and work your way up. Don't start at the top and wash down, start at the bottom and work up. Use plenty of water to rinse, as your working up the side of the house use plenty of water to rinse the bottom that you already washed. I would also buy or borrow a spray tank applicator to spray on the wash then use your brush. If you just dip in the bucket you will be wasting a lot of wash. I use a pressure washer and in spots also do what I am telling you. I have a soap dispenser on my pressure washer but use a spray tank applicator to spray the wash on. I think it saves on the wash liquid you are using. Get yourself a telescopic extension pole for the brush, it makes washing so much easier reaching the high areas. If possible work on shady spots or on a cloudy day. Avoid the real hot sunny spots, it makes for a better end result. (at least I think).

can you use this also for sidewalks and driveway?

Asked by: geno53
You can but you will find Zep's Driveway and Concrete Pressure Wash right next to this on the shelf. That's what I use and it works great on my driveways.

can I use this product for cleaning pool screen enclosure from mold and dirt?

Asked by: Mishkin
The pressure wash concentrate is not corrosive and I don't know what effect it would have on mold by itself. It does loosen the bond between dirt and vinyl siding so probably would have the same effect on mold. Need to be very cautious in use of a pressure washer at full pressure because it can severely damage screening. I'd use soap setting on washer wand first and then lowest setting to rinse the soap off after letting the soap soak the mold and dirt for 5 or 10 minutes.

Rated 5 out of 5 by from Zep house and siding wash We have used other siding products in the past with not the greatest results. This time we tried Zep on our own home's vinyl siding and on our rental house regular siding. Neither house had been cleaned for 3 yrs and were very dirty with with moss, grime and mildew. Zep worked great with our power washer to easily clean siding with NO scrubbing on both houses. Sprayed it on and let it soak just a couple minutes, then washed all grime right off. We will be using this product exclusively to clean our siding in the future. Highly recommend it.

Rated 2 out of 5 by from Fair product For everyday grit and grime on Vinyl siding, this product works very well in a pressure washer. But, for mold and mildew on siding in the deep south, you will still need the tried and true Clorox bleach and water with a tablespoon of dishwashing detergent. I used this product in a much stronger ratio than was noted on the bottle and the mold and mildew resisted my efforts.

Rated 4 out of 5 by from Zep This product alone doesn't seem to do much but it makes the pressure washer clean more effectively and made the white of the fascia cleaner than just the power washer alone

My husband and I recently purchased our first home, and it definitely need some TLC. Previous owners hadn't done any up-keep inside or outside. One of our first tasks was pressure washing the outside of the house to get rid of years of built up dirt & grim. This concentrate did a phenomenal job! We had thought the house was a light yellow, turns out its more of a beige/cream color!

Rated 4 out of 5 by from Seems to help in the cleaning process We have a few surfaces of our house that have some algae growth and I thought this product would help. It does seem to loosen some of it although I don't know if the power washer itself really does the trick and this wasn't needed. I guess over time I will be able to tell, but for now the rating is based on ease of use with the power washer I bought.

An economical siding wash that gives a clean surface with out overloading the siding with chemicals. ZEP is the only brand that I have used that is effective at keeping away green mold for most of the year. Last year the siding was washed in early September, and was still mold free into July. Very pleased with this and all ZEP products I've used.
