Third tip – Although many in the fence industry believe that pressure washing and scrubbing the fence can get a deeper clean, it can actually damage the wood surface. Most DIY websites and fence companies will recommend pressure washing the fence to clean it. What they don’t tell you is when the individual uses a very high setting to “pressure wash” the fence and what will happen.
High pressure to clean wooden fences will cause splinters, the fibers in the wood become very rough and when it is time to stain, the stain will Not adhere to the wood properly. We call this scarring.
If proper pressure is used with a power washer no scarring will occur. The best psi for cleaning a fence is 40-60psi. Fence Makeovers has over 20 years experience with cleaning wooden fences.
