Situation:
The "Sainte-Anne" cave was visited for about 170years with candles,torches and with carbide (acetylene) - lights. The soot of all these flames was deposited all over the cave and made everything black.
Last week-end we did a test to remove this soot ==> see this video

With such a result the Belgian caving community is planning a large scale cleaning action before the end of 2012 in this cave. We hope to clean as much as possible to make this cave shine again
Let this video encourage others to follow our example and let's clean-up some caves all around the globe.

Ps the test was done with pure water and with a little bit of presure in the can. Imagine what you can do when you use a "Kärcher" (pressure washer).
