Corian® is very easy to maintain, so you can walk on a Corian® staircase everyday in shoes without any problem. Dust is best removed from your Corian® stairs with a damp, soft cloth. Dry off with a soft cloth when you've finished. Are your Corian® stairs scratched? Small scratches may be caused by daily use. However, Corian® is a solid material and can therefore always be repaired.
