- ReVive - Headstone, Gravestone and Monument Cleaner - Trusted by Professionals - (1-Gallon)

Initially I wasn't too impressed with the results after it first dried, but as they state, this product keeps working for up to a couple weeks and keeps getting cleaner! You can see from the images that initially it did make a difference, but the patio was still green, then I looked again after a couple weeks at it was all gone! I did this with just a hose with a spray handle on it, so no pressure washer. Rinsed it right into the grass and it didn't kill the grass at all but took care of all the moss and algae that grew on my patio. The best part is that this stuff actually kills the biological growth instead of just pressure washing it off, which is basically like mowing the grass since you're cutting the tops off but not actually breaking down the roots. That's how this stuff works and it will stay clean now! Fantastic product and highly recommend, but don't judge the final results for at least 10-14 days, it'll keep getting better!

This product cleaned up the gravestones with ease!

Good product. Cleaned the stone well. Easy to use.

WORKS GOOD BUT NOT A MIRACLE CLEANER.

This is a great product. My husband and I went to the gravesite and used it on a large gravestone that had algae or mold on it. It was embarrassing to have the family name on such a pitiful looking stone. This product worked wonders! I have told my friends about it and showed them the before and after photos I took. We carried water from a water spout nearby by and followed the instructions on the label. I think, I sawed a video about it and watched a demonstration. I was so thankful to see such good results.

Not cheap, but works well on stained & mossy gravestones and doesn't kill suurounding grass / plants

You have to let it sit for a while and then use z brush to scrub off the growth. Stains do not come off.

Gets much of the black stains off the grave stone. It seems to keep working after the cleaning to brighten the surface.
