Hand wash your PVC clothes in lukewarm water with a very small amount of liquid detergent (flakes can stick to the PVC), making sure you wash inside & outside of the PVC clothing. Rinse inside & out thoroughly in cool water until all soap has been removed.

Turn the PVC clothes inside out and hang to drip-dry. When the polyurethane inside is dry, turn it right way round & allow PVC outside to dry. Never put it in the dryer or use heat to speed up the drying process as heat can melt the PVC and the fumes from burning or smoking PVC are dangerous.

As long as the PVC clothing isn't soiled many people will just freshen the polyester inside out with a product similar to Fabreeze and wipe the PVC outside with a damp sponge.
