Waste of money
Would Not RecommendI bought 2 gallons of this product to treat dark spots on my roof. I applied in the evening on an overcast 70° day making sure roof was thoroughly wet. As instructed, there was no rain in the forecast. I realized it wouldn’t work instantly but after waiting 3 months, I saw no difference in the stains on my roof. I actually had a small amount left and retreated the worst area. After waiting again I still saw no improvement.

Works Great for Me
Would Not RecommendDon't understand the bad reviews. I live in the woods with alot of shade and this stuff is a lifesaver. For years I struggled with pressure washing every year. Now, after the initial application, once every 2 years keeps my house siding looking new. Don't know what the others are doing wrong?? but I've been using this stuff for about 5 years now and love it,

Don’t waste your money. Use water and Clorox. Does a much better job.

The 6-12 month timeline is for very severe stains that have built up on a surface for a while. Most customers will start to see results a week or two...
