My wife and my sister wanted to do a project for the community, especially with Memorial Day coming up. My wife purchase a small sprayer bottle to use as a “trial-sample”. We haven’t used it long but saw immediate effects on the headstones that we used it on. So far, we have only scratched the surface of the veterans’ headstones and have posted pictures on facebook. The community is going wild over the short-term results and we will continue to update with the continual long-term results.

I have used this to clean statues around town that had many years – decades of pollution and lichens. The results are a amazing and did not harm adjacent plants. I applied as directed and scrubbed moderetly. The results were fast. I did lightly apply additional cleaner and over the next week or so it continues to clean. Highly recommend.

I’ve used D2 Biological Solution on 50+ monuments in my old cemetery while I was their sexton, & all I can say is, WOW what a difference. I would highly recommend this product if you were cleaning your families headstones or taking up the business of doing the same. It’s an amazing product.

Used it to clean a former President and First Lady gravestones. Danby White marble. North sides were entirely green. Now, more white than they have been in decades.
I would caution that white marble will turn an orange color when used. As if someone poured rusty water over it. Don’t panic, if you scrub, it’ll go away quickly. If you spray and walk away, it might take a day or two. Great results though!

Purchased this product and it never arrived through no fault of LimeWorks. Called customer service and talked to a friendly voice who apologized for the item not being delivered, even though it was not their fault, and immediately started the process of sending me the item again. Many companies have quality products but few have outstanding customer services like LimeWorks. Thank you.

Very easy to use did a great job of cleaning the granite tombstones but if they haven’t been done in awhile I suggest a second application use alot of elbow grease when scrubbing.

I know the shipping cost probably can’t change much, but it’s half the cost of the product.
I look forward to using it and seeing if it works well.
Thanks.

Delivery was fast. But, must have been banged around, because the package was wet on one side. So, some obviously leaked, but not much.

D2 is a miracle. I clean abandoned veteran headstones, and this solution is a godsend. It safely and effectively cleans the stones and leaves them standing with dignity. And the time that it arrives at my home from the time I place the order is perfect, so much faster than I expected. I love D2, and I will only order from Limeworks when I need more! Thank you!!!!
