How Often You Should Clean Your Toilet Tank?

Experts suggest cleaning your toilet tank twice a year to avoid mildew, rust, and grime—and to prevent a buildup of minerals that can damage the parts. If left unaddressed, not only can bad smells permeate the bathroom, but the toilet’s components might corrode and rust.

Using Vinegar to Clean the Toilet Tank:

From mildew to hard-to-tackle calcium deposits, vinegar is an inexpensive, natural cleaner that dissolves a range of bathroom offenders, including toilet tank rust. Choose a white vinegar (either distilled or the basic white vinegar will work) over a colored variety, as the latter could stain your toilet.

Maintaining Your Toilet Tank

To avoid nasty buildup and extensive cleaning sessions, consider using drop-in tablets to help maintain your toilet tank and prevent the formation of mildew, rust, and bacteria, making it a lot easier to clean the next time around. Look for tablets that are non-toxic and bleach free—the harsh chemicals found in some drop-ins have been known to cause corrode and cause damage to toilet tank parts.
