A couple of handy tips:
- Rinse your scrubber out occasionally. The ink does transfer from the stamps to the scrubber, but it will stay with the scrubber until it's cleaned. Just occasionally works, depending on your use level. I do it about once a month.
- After cleaning your stamps, stamp the cleaned stamp on a piece of paper. This will help remove any cleaner. When you let the cleaner dry on the stamp, it can affect how well the stamp picks up ink next time you go to use it.
