In-tank toilet cleaning tablets

What they are
- Small tablets or cartridges placed in the toilet tank. They dissolve in water and release cleaning chemicals.

What they do
- Help prevent stains from minerals like calcium and lime, and mold.
- Keep the toilet bowl cleaner between scrubs.

Active ingredients
- Most tablets use chlorine bleach as the main cleaning chemical, but some use other active ingredients.

History
- Invented in 1978 by Flushco, Inc. and sold under the brand 2000 Flushes (now owned by WD-40 Company).
- Other brands, such as Scrubbing Bubbles, Clorox, and Ty-D-Bol, also offered their own in-tank tablets.

Pros and cons
- Pros: Easier maintenance, less scrubbing, and a cleaner-looking toilet.
- Cons: Bleach can damage rubber gaskets and steel parts; blue dye can hide mineral deposits. Many toilet manufacturers and plumbers discourage in-tank cleaners and some warranties may be voided if damage occurs.

What to consider
- Check your toilet’s warranty and follow product instructions.
- If in doubt, you can clean the toilet using other methods.
