Now, I know the reaction most would probably have to anything Harbor Freight sells, but I've found that after applying an LSP, if the customer doesn't pick up their car right away, I may end up with a light layer of dust on the car. To remedy, I've been simply blowing it off or using a microfiber towel, but have been wanting a California duster type tool. While in HF the other day picking up some random tools for the house, I came across this:
Microfiber Exterior Car Duster
I picked it up as the price was too good not to (especially with the 20% off coupons I always get).
It seems to work great, is very soft and gentle on the car. However the instructions on the packaging says they recommend never washing it as the fibers have a wax on them already that aids in picking up dust.
That had me a little concerned that might also be leaving behind something on the vehicle that I don't want. Any cause for concern there? Are others using similar tools or should I ditch it?
