Where do you get leftovers in Pokemon White?
I guess it's Chlorine, or Bleach in the tap waterThe ways to keep it clean are: 1Dry the sink with dry towels, after using the tap water2The white stuff will be dissolved in the same element, the Bleach, so, use your Bleach to dissolve it, and wipe it out3You probably could use any kind of soap instead of the bleaches.
probably soap scumTry Comet, or Soft scrub.
It's calcium buildup aks lime scale from your waterBuy Lime Away, it's stronger than using vinegarIt's in the cleaning products aisle of the store in a bright green spray bottle.
Calcium is my best betI managed an Apartment Community that had it in EVERY unitWhen cleaning we would use an sos pad, dry it off and use Pledge polishIt would give it that shinny look and water beads off of it like was on a car.Sometimes we would have to use a screwdriver to chip it away at the bottom of the faucets and knobs!
Using the Dowsing Machine on Village BridgeIf you can't get there yet, beat the game firstAnother way is to use the ability PickUp, but the Pokemon with it has to be at least level 81 to even find Leftovers.
