Hello,
Timmy ...
... rubbing off the factory paint with mineral water is a labor intensive task (took me 30 minutes of heavy work once to rub off stubble from a pirate face--there must be a sanding-type tool that will do it better).
This is another one of those times that you are very fortunate that you live in the United States!
All you have to do is go to your local supermarket and visit the laundry aisle ...
Look for
Bar keepers Friend (powder).
see attachmentAfter you've made your purchase, and have taken your magic powder home, take your magic powder and your most challenging Klicky into the kitchen.
1. Put a little Bar Keepers Friend powder in the kitchen sink. Dampen your finger (drier is better than wetter).
2. Gently touch the little pile of powder with your damp finger.
3. Look at your finger. A small amount of powder should now be on the part of your finger that the police use to take your fingerprints ...
4. Gently rub the marking on the Klicky that you want to remove.
5. Be surprised and amazed at how easily the unwanted markings disappear.
NOTE: I can't stress the word "GENTLY" enough! It doesn't take very much pressure to remove the markings! (However, probably the only damage that you can do, by NOT being gentle, is to make your finger a little red.)
Have fun and all the best,
Richard
