The answer to 'how to care for fence' is to regularly inspect, clean, and maintain your fence to keep it in good condition. This includes checking for any damage or wear, cleaning the fence to remove dirt and debris, and applying a protective sealant or stain as needed.
Start by visually inspecting your fence every few months, looking for signs of wear such as loose boards, cracking, or rot. Clean the fence with a mild detergent and water, using a soft-bristle brush to remove any built-up grime. If you have a wooden fence, apply a wood sealant or stain every 1-2 years to protect the wood from weathering and decay. For metal or vinyl fences, wipe down with a mild cleaning solution to keep them looking their best.
