I am going to refinish a patio door but noticed that the wood grain has weathered and turned grey. What is the best way to remove the grey out of the grain that is weathered? And how do you get into the nooks and crannies to get it sanded?
We recommend getting it cleaned with Krud Kutter Original Concentrate Cleaner. Spray it on the grain and then let the cleaner sit for about 30 seconds. Then give it a light pressure wash or scrub brush. Then, begin your normal prep work, sanding, etc.
