Popular Toilet Rim Block FAQs

What do Toilet Rim Blocks do?

These block-shaped toilet cleaners come formulated to slowly dissolve in water, which in turn, cleans, fights toilet stains, and leaves your bathroom smelling fresh. Depending on the formulation, toilet rim blocks can also fight limescale deposits, keep cleaning your toilet in between use with the help of foaming action, and colour your toilet water.

What is the Best Toilet Rim Block?

Settling for the best toilet rim block is a matter of individual need and preference. If you are dealing with excessive limescale deposits that stain your toilet then you’ll want to go with a product that can help you fight this problem. Likewise, if your aim is to have a gleaming clean toilet that smells heavenly, then that should guide your selection.

Where Should Toilet Rim Blocks be Placed?

As implied, rim blocks come designed for placement under the rim of your toilet. Most come encased in a small basket/holder allowing for a hassle-free “hook and place” installation. Some are cage-less for in-cistern placement, while other “loose” rim block cleaners typically come with a hook to enable placement under the rim of your toilet.

How do You Use a Toilet Rim Block?

You don’t have to do much to start using some toilet blocks, except for placing it on your loo and allowing it to do its magic. Perhaps the only heavy-lifting involved is adjusting the unit’s placement in line with water flow, but besides that, there’s nothing more you’ll need to do. Each individual toilet block brand usually also comes with instructions to guide you on the installation and replacement process.

How Long do Toilet Rim Blocks Last?

Just about every rim block will give you anywhere between 200 up to 1,000 flushes-worth of use. Remember that they dissolve with each flush and that ultimately means that they are bound to run out at some point. Most brands also sell them in multi-block packs with two to four or even 12 pieces.
