What is Vinyl?
Vinyl is a plastic made from polyvinyl chloride (PVC). Vinyl is manufactured in different ways in a number of forms and in varying qualities for thousands of uses. A vinyl's topcoat holds in plasticizers, softening agents which keep vinyl supple.
Vinyl is a UV-sensitive material which degrades when exposed to sunlight. Maintaining the integrity of the topcoat and protecting against UV damage are the keys to keeping vinyl looking and performing "like new". 
Simple Cleaning
Keeping vinyl clean is an important part of routine maintenance. Dirt acts as an abrasive and can also wear out the thread in seams. Mildew grows on damp, dirty vinyl.
The recommended vinyl cleaning method:
-
Rinse with cool water.
-
Wash with soap (not detergent) and water using a soft cloth or sponge. For stubborn dirt, a soft bristle brush may be used.
-
Rinse thoroughly with water and allow to dry.
-
Avoid harsh cleaners, abrasives, petroleum distillates and alcohols.
Protecting Vinyl
Using the wrong vinyl "protectant" product is worse than using no vinyl treatment product at all! Avoid vinyl treatment products that contain any type of oil, have an oily or greasy feeling, contain petroleum distillates or leave a coating that dries like wax. If a product label says "flammable or contains petroleum distillates", do not use on vinyl.
