>>Mine looks really dirty now, but still works great. I give it a good shake before each use to dis-lodge any particles and ocassionally give it the once over with the vacuum.<<
Ive got a white M3 so I never noticed any streaking even when new. Do those strands of yarn just keep their ability to lift the dirt? Would anything good be accomplished by occasionally spraying some spay on carnauba lightly on the yarns and letting it dry?
Ive read provisos to, ' ... dont be fooled by imitations.. only use the wood handled ones...', etc, etc. Well, I have two; one is wood handled, and one plastic.. they BOTH say California Car Duster, or whatever, and they both have the same black plastic wrapped holder. I wind up using the plastic handled one for the lower car and wheels, and the wooden one the upper panels, and horizontal surfaces.. Arent they BOTH genuine cal dusters? Otherwise, they couldnt label them as such I would think.
