As a roof and concrete cleaning specialist with many roof and driveway cleans behind us, I can truly say that these products work extremally effectively and perform exactly as per the guarantee by Pacific Northwest Green Cleaning Products Canada. We use these products on all of our jobs with confidence and great success. Organic & friendly to the environment with no danger to plant life the green alternative makes total sense.

After using two other products, I tried Roof Wash and was immediately very impressed. The results were evident a very short time after the product was applied, and has continued to improve as the dead algae and lichens get washed off by the rain. I applied to product on a five year old cedar shake roof and it has obviously extended the future life of the roof. I would like to try the Cedar Wash the next time I do the roof and look forward to seeing the results of that product.

Thanks.
