I just picked one up and it says:
So, how often do you wash these things? Is it true that these dusters can go for long period without wash and NOT scratch the car's finish? It seems to have a wax finish on the threads. Any suggestions how often I should wash the duster?The 'dirtier' it looks, the better it works...If you feel the need to wash the 'Original California Car Duster' for any reason, hand wash only using mild soap...
