Some very good points made in this post… remember preservation is about doing no harm. It’s not fast and it’s very often not easy. If you are doing the fast and easy method you are doing something wrong.
🪦😵💫A grave mistake: Using a pressure washer to clean a headstone.
I have recently noticed that more gravestones in my local cemetery have been cleaned with a pressure washer. While they look great and provide instant gratification, let me tell you the downside of this method.
1. The psi is too harsh; it can erode the stone's surface, cause flaking, destroy carved details, and wear down the inscription.
2. Forcing water into small cracks can allow environmental elements, such as lichen, to grow inside the stone, causing your memorial to deteriorate faster from the inside out.
3. The Association for Gravestone Studies does not recommend this method.
When treated with care, I can achieve the same results without the risk. 🪦❤️
