Mud Removal from Calcite Flows and Stalagmite
Very obvious and quite easy, though rather tedious! Thought should be given to whether the cleaned area should be taped off or a route through marked with small arrows.
Water sprayer(s); sponges - at least 2, one for heavy soiling, the other for cleaning; brushes. The equipment in use in Torca La Vaca is shown here.
Work from the inside to the outside of the formation(s) so that dirty water is washed away from the objects. In Torca La Vaca there was a nearby source of clean cave water and the dirty washing water could be sponged up and squeezed out down rifts which connected with the active streamway below. Other situations may not be so amenable to removing the muddy water, eg muddy formations in dry passages.
