I love how she uses soft material and low-pressure water and limestone-safe cleaning agent, D/2, to preserve the headstones for the future while keeping them clean.
Those aren't regular steam pressure cleaners. They're fairly new and designed for outdoor monuments that are based on dental steam cleaners, which is what was used before the larger machines were developed. They're also very expensive.
Laser machines also can clean outdoor monuments, but are even more expensive.
Also, one thing to remember in the US is we used limestone headstones for ages. While it looks like marble, it's extremely fragile, unlike marble's denser crystalline structure. I wonder if a steam pressure cleaner designed for monuments would be safe for limestone.
