How to Fix Oxidized Vinyl

Vinyl siding is generally cost-effective and requires less maintenance than wood, but that doesn't mean it requires no maintenance at all. Acid rain and UV radiation from the sun combine to cause oxidation on the vinyl, resulting in a faded, chalky appearance over time. The sooner the oxidation is dealt with, the simpler it is to remove. Repairing the oxidized vinyl requires a vigorous cleaning process to both remove the oxidation and to restore the vinyl's appearance.

Things You'll Need

Garden hose
Pressure attachment

Liquid dish soap
Sponge or soft brush

Instructions

- 1
  Rinse off the vinyl with a garden hose and a pressure attachment. Avoid pressure washers because they supply too much force and may damage the material, while a garden hose won't. Aim the nozzle at a downward angle so water doesn't seep up and under the siding.

  Mix several drops of liquid dish soap into a gallon of hot water. Apply the solution to the wet siding with a sponge or nylon scrub brush. Start at the bottom and work your way up the siding. This helps eliminate the oxidation. Avoid using a metal brush, because it scratches the vinyl.

  Rinse off the siding again with water once you've scrubbed it with the detergent. Repeat the steps until all the oxidation is removed and the vinyl is restored.
