Can i use a wet qtip to clean spots on dry denim?

I have some small spots from snow/salt mix on my puma evisu's legs... im kinda new to dry denim and wasn't sure if that was going to leave faded spots after it dries. Thanks.

washing them works

I just don't want them to shrink! it took me awhile to get these to loosen up(puma evisu slim fit). Thats why i wanted to spot clean. I wasn't sure if it would

Let the spots fall off with the denim

I frequently get specks of dirt on the back of the legs when walking me dog. I have never done anything to clean these spots off; they simply wear away naturally.
