While at his plot I noticed a stone that I used to demonstrate how to clean a tombstone with D2 biological solution. The 10 minute video can be found on YouTube by clicking on this link. In September 2014 a blog post was created on this process. However today I was very surprised. I have known for a long time that all tombstones are not created equal. Some stones cleanup better than others. But this stone really whitened and brightened over the fall through the early summer. The photos below will speak for themselves.
The above photo was taken before cleaning with D2.
The above photo was taken about one month after cleaning with D2.
The above photo was taken this morning; 8 months after cleaning.
