Quick Clean Felt Cleaner

Great deep cleaning for groups and stains - just be careful to wear goggles as the grit is very fine and don't want to get caught with splashing into your eyes

Used on several granite family headstones a few weeks before Memorial Day Weekend. Hands down the Best headstone cleaner I have ever used. Highly, highly recommend this product.

I wish it were a large bottle but it is one of the best products that you can use

This stuff works amazing on tombstones! Amazing!

It did okay but I may not have given it a good test yet.

I have used D2 in the past, but decided to try Endurance since it was a cheaper option. The tombstones were very old and covered in decades of grime that came off pretty easily. Endurance turned half of the stones orange and red, but this went away after a day or two. I will be buying and using this again.

This was first time trying Endurance cleaner. As soon as I received order I drove to a small rural cemetery near me. I used up the gallon in one hour. I sprayed 16 stones from the 1800's. I went every other evening to spray stones with water. Did not know the black stones were white n black marble underneath the black yuck. Today was day 9. I went with 2 gallons of water and sift scrub brushes. The amount of debris that came off with light scrubbing and rinsing with water was impressive. On day 3 the change was impressive enough that I ordered 4 more gallons before free shipping was over. If you want fast results, esp with low number of stones to clean D2 might be faster. But takes a lot of scrubbing, I would have gotten fewer stones done if I scrubbed them from day 1. Now my teenage grandsons are upset I did this without them.

I am very impressed with this product. I started by buying 4 gallons based on a recommendation from a friend. Next purchase was a 5-gallon bucket and most recently 10 gallons to get a 15% discount. I am the president of a cemetery association and have set a goal for this year to clean all of our 58 veterans' tombstones. Attached picture is one of my first attempts.

Had used a previously leading brand in the headstone cleaning world. Switched to Endurance after spraying and comparing stones head to head in a couple of experiments. Completely impressed with Endurance with the results (and cost!) not to mention the outstanding customer service through Atlas. Going to go back to previously cleaned stones to re-spray with Endurance for even better results. The photo attached is an almost 100 year old stone after 18 days. Looking forward to trying other stone cleaning products in the Endurance line.

I've been using this since it was released in June 2025. It's far more effective than D2 at getting something clean using the “spray and walk away” method. I used up my last D2 on a few stones that look like they were never actually sprayed compared to the ones sprayed with Endurance. The stones in the photos here were cleaned using all Atlas products (brushes, plastic scrapers, and Endurance). Atlas is great at what they do and everyone I've had contact with on their staff has been helpful. They know what they are doing and they clearly enjoy it too. Support a local CT business!
