Washing your patio cover – use a gentle cleanser – we suggest Blue Dawn dish soap, a very soft bristle brush & water, wash by hand or with soft brush.
We do not recommend using a pressure washer on your patio cover and can not warranty any chipping or damage that is a result of this action.
In the case of a spliced glass, we do not recommend additional water pressure in this area, please be careful and gentle when washing around any spliced areas.
There are many companies with experience and supplies meant for washing difficult areas – check out Shack Shine or Wash Me!
