How often do you wash your drying towels?

So I have been wondering..how often does everyone wash the towel they use to dry their car..I have been washing mine after every car wash but been thinking..if I just washed the car and it was clean water drying it do I really need to wash it every time.

Generally speaking, I wash mine after every use.

Sometimes every other time but I wash my car often.

I wash all my towels the same day I use them. Prevents products from staying in the fibers too long

Every single time. If you don't, and you wipe it over a spot that didn't get washed well enough, it's going to pick that dirt up. If you don't wash it, the next time you go to use it you're going to grind that dirt back into the paint.

How about spray wax and QD towels which have only touched a clean car after being washed?

Still after every use - you need to clean out the QD and (particularly) the spray wax from the towels, which is easier if done sooner.

I guess my other thought is..since my car is not a DD and sits int he garage most of the time and when i do wash it it really isnt dirty but just has a layer of dust on it.
