Plastic objects and surfaces often collect dust, dirt and grime, which can stain and discolor plastic. Cleaning plastic is necessary to kill germs, remove grime and improve the overall appearance of plastic objects. Bleach is a pesticide used to kill bacteria, whiten materials and sanitize many objects. This disinfectant can be used along with soap solutions to clean and sanitize plastic items and surfaces. Cleaning with bleach can also help whiten yellow plastic objects.
Apply anti-bacterial liquid dish soap to a clean rag. Dampen the rag with warm water.
Rub the rag over the plastic. Scrub the plastic with the rag until the object is clean.
Pour 1 gallon of cold water into a bucket. Add 1/4 cup of household liquid chlorine bleach to the water.
Dip the plastic object into the bleach solution. If the plastic item is too big to dip into the bucket, dampen a clean rag in the bleach solution and wipe the object with the rag.
Allow the object to air-dry.
