You should clean dirt and grime to prevent buildup and discolouration and to maintain your fence’s appearance.
You will need to be more careful about mold, mildew and algae and prevent these from forming on your fence.
Mold, mildew and algae all can damage the integrity of your fence as it causes the wood to rot.
Even though pressure washing can be done to fences with a lower PSI, but we prefer to use softwashing method for better results.
