For spot stains use a fabric cleaner (303 Cleaner & Spot Remover).
1. Pull the belts from the retractor and gently close the door on the belt, clean and allow to air dry before opening the door and retracting the belt. Do not use bleach, strong detergents, or dye on the seat belts as this may severely weaken them and render them ineffective in a crash.
2. Once fabric is dry apply a fabric protection (303 High Tech Fabric Guard).
3. While you are cleaning the belts, take the opportunity to closely inspect them for damage and security of attachment. Ensure here are no cuts, tears or abrasions (you should always inspect for damage etc if they get caught by a closing door).
4. After a while the seat belt mechanism becomes slow and/or will not retract when released. This can be avoided by cleaning the upper anchor; as the seatbelt retracts it leaves behind a film of dirt, which builds up over time. Use compressed air to remove dust and then using a cotton bud and some Isopropyl alcohol (IPA) you can clean the seat belt anchor/retracting mechanism. Once clean add some Plexus Plastic Cleaner to provide lubrication.
Maintenance - clean seat belts with a 5:1 P21S Total Auto Wash / distilled water solution. Ensure they are thoroughly dried before use.
