How to Clean Vinyl Fencing
- 1). All you need to do is put a couple of squirts of the dish detergent into a bucket of water. Swish it around with your hand.
- 2). Dip the sponge into the water. Wipe the mold off of the vinyl fencing with the detergent solution. Repeat until it looks clean. Mine came off pretty easily!
- 3). After you are finished cleaning the mold off, rinse with a fresh bucket of plain water. You can wait another 6 months to a year until you need to do it again.
