For the cleaning of terrazzo floors we use special grinding or
polishing machines for floors. Instead of abrasives we use nylon
pads in combination with water. The nylon pads are available in
different degrees of hardness. The use of a small amount of scouring
agent can be helpful. Because of the soft pads the scouring agent
doesn't scratch the surface. After the cleaning we treat the
terrazzo with a mixture of turpentine and linseed oil. It's very
important to remove the remains of the oil after the treatment
before it starts drying.
