Cleaning Delivery Bags

How does everyone clean the delivery bags?
And how often do you do it?

We buy cheap nylon bags and when they get too dirty we just throw them away and get new ones. I’ve tried to wash them in the past, but didn’t really do much.

We turn ours inside out everynight to let the moisture dry up/escape. It’s worked well for us.

After 18-30 months we just replace them.
