  • Your tank might get filled with dirt, dust, and debris. These nasty particles can reduce the usage benefits and longevity of your tank. Over time these particles can erode the inside such as the steel of the toilet tank.
  • Built-up mold in the toilet can make the bathroom smell nasty.
  • It’s hard to notice the rust rings, and bacterial growth that gets built up in the tank unless the user lifts the lid and looks inside. Rust will affect the operation of the toilet badly and bacteria will produce nasty odorous water that will end up in the bowl after every flush. 

How often Should I Have to Clean my Tank?
