seat belt cleaning

I did this on a 70 charger i had ,worked excellent they came back like new beleive me.Roll them all up in ball buy enough varsol to go over the top , place them in a bucket , leave them four a couple of days take them out then pressure wash each one with a good degreaser to take away the smell and let the dry , sounds like a recipe i know, but it makes them as soft and clean as the belts in a new car .
