Here's a thought. Get one of those really small zip lock containers, then a small air stone and air pump. Sink it in a corner and allow that to replace one of your water dishes (salt or plain). My bubbler has salt water and at times the glass inside the tank does get a salt build up. It wipes off easily, but if you don't want to bother with that use it for the plain water.
