By walking the Reinstreifer surface dirt is wiped off from the sole of the shoes and falls in the space between the profiles. Due to the sling-free needle felt and the sole boost the Reinstreifer surface is able to regenerate itself.
But well-done maintenance will pay off:
Vacuum the Reinstreifer surface in regular intervals and clean the mat bed. Therefore roll up the Reinstreifer up to its half and sweep or vacuum the ground. In case of extreme dirt you can also use a high-pressure water blaster. 100 bare water pressure is no problem for the needle felt.
