Automatic tank cleaning tablets

These tablets drop into the cistern and dissolve slowly, releasing bleach-based cleaning agents with every flush. The sustained-release formula targets urine scale, limescale and rust stains without manual scrubbing. Each 20 g tablet works for about 15 days, and the 12-pack covers roughly six months of continuous treatment.

Suited for low-maintenance households

Homeowners who want a set-and-forget solution for daily bowl hygiene will benefit from the automatic dosing. Buyers who need instant stain removal or prefer to control the exact amount of cleaner per flush should look at liquid or gel alternatives.

Bleach-based sustained release

The active bleach ingredients create a protective film that prevents new deposits from adhering to porcelain. Neutral, dye-free formulation avoids damage to septic-system components and metal or plastic tank parts.

Questions about this item

Will the bleach-based tablets create strong fumes or extra heat in the bathroom if they run continuously?

The tablets release cleaning ingredients with each flush; you may notice a scent, but they produce no measurable heat or fumes beyond normal toilet use.

Does the toilet tank need any special fittings or a specific flush mechanism for the WP-01 tablets to work?

No special fittings are required; simply drop one 20 g tablet into a standard tank, wait 30 minutes for it to dissolve, then flush as usual.

Are the neutral, dye-free ingredients safe for older metal or plastic tank parts and septic systems?

Yes, the formula is designed not to damage any metal or plastic components and is safe for septic tanks.
