When plastic furniture is stored outdoors, weathering elements build up on the plastic and cause a cloudy, oxidised film that is difficult to remove. You may be familiar with this when you or a guest sits down on a plastic chair and white chalky film transfers onto clothing. To remove this oxidisation, use cleaning ingredients that break apart the build-up without damaging the plastic furniture.
Fill a bucket with 1 gallon water, 3/4 cup bleach and 1 tbsp of either dish detergent or washing powder.
Rinse off the furniture with your garden hose.
Dip a nylon scrub brush into the cleaning mixture and scrub over your plastic furniture. Continue across all of the furniture and let the cleaning solution stand on the plastic for about 15 minutes.
Rinse the furniture once more with your garden hose and dry with a clean rag.
