MTBioinUS Cleaning Set - 1 Quart with 2 Nylon Brushes + 2" Plastic Putty Knife

We used this to clean a headstone over 100 years old. It worked great. At first I thought it didn't do well, but a couple of days later it had continued to work. It continues to work in the outdoor weather.

I used D2 to clean a 100+ year-old gravestone that was covered in various types of moss, lichen, rusty stains, etc.. I was pleased with the results I got from D2 along with some gentle use of the included brushes. The real surprise came a couple of weeks later when I stopped by and found that D2 had indeed worked as advertised. It had continued to remove stains and plant material, and the gravestone was amazingly clean and white.

I am very pleased with the cleaning ability of the product. However, it did kill the grass all around the area I was working on. Other than that, it worked pretty well with some elbow grease.

I used D2 on the 100 year old statue at my family’s gravesite and after only a month after applying the solution, it worked like magic… it was a slow change, but it was exciting to see the difference with every passing week. The statue continues to get brighter and brighter.This statue means a lot to my family, so I was a little bit nervous when the spray turned parts of it it orange initially, but with some quick internet research I was comforted by the company (and customers) all saying that the coloring is common and it fades away with time. They were correct. In just a month I’ve seen a noticeable difference, and there’s still more to go! Apparently it continues working it’s magic for about a year. I never imagined that this statue would turn white again. D2 is an amazing product. I will tell everyone about this product.

Needed to clean up some old headstones. On some the headstones, I sprayed and then scrubbed, and rinsed with water. Worked nicely.On the very old headstones, I sprayed plenty and just left them alone for a couple of months. That actually worked better than the shortcut scrub/rinse.

I bought these to clean headstones before Memorial Day this year, and let me tell you - it's unbelievable how well it works! One of the stones I was cleaning was the white military stone, and it had grown black mildew so thick on the stone it was getting a little difficult to read the inscription. We sprayed this on and left it a few minutes, then cleaned it with a soft brush attached to a cordless drill. AMAZING. I was a little panicked at first because the product seemed to turn the worst of the mildew an orangey color, which wasn't good. But the longer it sat on the stone, the orange came off (I think it was just part of the process) and left the lovely white stone looking brand new! I think it got even lighter over the next day. I was super proud of the job when it was done! I initially thought it was pricey...but nope. I'll buy more.

I bought this to clean a relative’s headstone. It was so nice to use that I ended up cleaning a few more stones around theirs. The kit was perfect and great quality items. I did end up going to my local hardware store to buy a container to spray water.

I used this to clean headstones. It worked fantastic! Sprayed it on, left, came back weeks later and it was like new headstones, clean! I actually started to use it on other peoples headstones that were neglected. Pricey but definitely worth it.
