Cleaner Tablets for Toilet Bowls

Metra CN-US-004-1 tablets dissolve quickly in the bowl to remove grime, mineral deposits and limescale rings. The effervescent action lifts stains so the surface looks freshly scrubbed after each use. A 24 pack supplies up to 12 months of weekly maintenance.

Households with Hard Water and Septic Systems

These tablets suit homes where hard water causes stubborn limescale and where septic-safe cleaning is required. The formula freshens and deodorises while helping prevent new buildup between deep cleans. Buyers who want more storage or a different cleaning format should look at something else.

24 Tablets per Pack

The pack contains 24 tablets, providing a full year of cleaning when used at roughly two tablets per month. This count determines how long the supply lasts before reordering. No other quantity is included in this product.

Questions about this item

How often do the Metra CN-US-004-1 tablets need to be replaced?

Each tablet dissolves during a cleaning cycle; the 24-count pack is designed for roughly two tablets per month, giving up to 12 months of use before a new pack is required.

What stops the tablets from working continuously in the bowl?

The effervescent formula acts only while the tablet dissolves; once the fizzing stops the active ingredients are spent, so the next cleaning session needs a fresh tablet.

Does the product generate heat, noise or extra power draw while it sits in the tank all day?

No, the tablets are passive chemical cleaners — they produce no heat, make no noise and consume no electricity while stored or during the dissolve cycle.
