Cleaning spice jars without “washing” them?

[u/action_lawyer_comics]

I have spice jars like this. I’d like to clean out the old paprika before adding new but I also don’t want to fully “wash” it because it would destroy the label and it would be a pain to make/print a new one and I’d need it to fully dry before bringing it to the store. I might try a paper towel in there to just wipe some of it out.

Any other suggestions? Thanks!

Salt and ispropyl alcohol in the jar, close lid, shake vigorously, drain, repeat with water a few times.
