Seat Belt Webbing

[mightyatom]

Does anyone have any tips for re-vitalising seat belt webbing. The seat belt in my car are the originals but have been weathered a little. Although the webbing is still good, it is a bit dried and not as flexible as it should be. Is there some sort of conditioning cream or something I can use for this like you do with leather seats, or will moisturizer work ?

Any tips would be great as I don't want to spend the money to replace perfectly good seat belts but it would be nice to have them supple and flexible.

Thanks
