Questions & Answers


Is this product "safe" to get on the glass of my house windows while cleaning mold and dirt off t...

Asked by Stacy September 15, 2020

I have found the cleaner to be quite safe. I have tried to minimize the amount that has gotten on non-mold surfaces but the liquid that has gotten on them has not caused any issues.

Will this damage the exterior of white aluminum gutters if manually diluted and applied with a brush?

Asked by Jc May 9, 2020

I apply it directly to the gutters from the pressure washer and it does clean them. It won’t harm your gutters, and it doesn’t harm plants either.

My washer doesnt have a detergent tank. Can this be used with a siphon tube?

Asked by Steve May 9, 2020

I do not know. I put it in a bucket with water and used a long handled brush to clean my siding. I then rinsed with a garden hose. It cleaned my siding very well. I would recommend the product.


Asked by PAULA April 4, 2020

I didn’t use a pressure washer.

Can this be applied with a 1-2 gallon pump sprayer? Then using a garden hose to wash it off?

Asked by Spyder March 23, 2020

I put the diluted solution in a bucket and applied with a brush and then rinsed off with a hose. Worked great. Brush really cleaned the siding well.

Do you have to put the suction hose straight into the concentrate bottle or can you mix in a 5 ga...

Asked by KyHoosier February 21, 2020

Put it in my pressure was tank only. From there the pressure washer pump took over.

Is it good on metal roofs Is it good on metal roofs

Asked by Jr November 22, 2019

This is a vinyl cleaner only!

Is it good on metal roofs

Asked by Jr November 22, 2019

This is for vinyl. On a metal roof, I would suggest Purple Power which is an awesome cleaner.

Does this product work with second story soft wash nozzles, using 3200 PSI pressure washer?

Asked by Rey July 14, 2019

It works with my pressure washer that has a tank for cleaning solutions, which does get sprayed on using the low pressure nozzle.

Is this product safe for pets?

Asked by Pepsi May 27, 2019

This outdoor cleaner does the Jo
I have owned the same home in Georgia for 20 years, after a mandatory move from Connecticut to Atlanta area. During my 20 years I have used at least 10 different powerwash brands. Some were Corrosive, some took care the algae & pollution, but left a residue. Some mixes were very bleach smelling. I personably like and trust the Simple Green product line. This product did a great job, no residue, no algae, no dirt. Like any exterior cleaning, spray on and let the product sit for 5 to 15 minutes. Next put sprayer on rinse,start spraying from the top to bottom. This product works well

Excellent Cleaner!
This Simple Green Cleaner works great! It is also safe for the plants, etc. Just follow the directions on the bottle, wet everything down first. Easy to apply with a pressure washer, and then rinse. Mildew falls off like magic. I am very impressed with how well it works. I really like the Simple Green Line of products and highly recommend this House and Siding Cleaner. No harsh odor either. A little goes a long way. The instructions say that if there is really no 'heavy dirt', you can cut it 50/50 with water. If you look at the pictures here, I did not use it full strength but cut it with about 30% water and what an amazing job it did! I was not able to reach this section of my house for about a year and a half. So I wanted to show this section especially, after a year and a half buildup of dirt and mildew. Product worked fantastic!

I didn't like it
I used this stuff without and with a pressure washer. The instructions ask you to spray it on then use a pressure washer. I sprayed it on and used a pressure washer and it did very little in regards to dirt removal. If you spray it on, then use a scrub broom or brush, it will work. So, this little experiment tells me the pressure washer does the work. In reality, a pressure washer will clean most anything without an additive soap.

Simple Green makes a great line of products for those of us who prefer to be a bit more gentle on the environment. The aroma is pleasant and it works as well as any other siding cleaner with a pressure washer. We used it on painted cedar siding and it took away a fair amount of Winter's dirt. For more stubborn areas spray and leave it for a few minutes before washing off. Concentrate goes a ways so it's an econmical way of Spring cleaning the exterior of you home and outside buildings. Much faster and easier than new paint.
