Drugstore toilet block aimed at keeping the cistern and bowl cleaner with every flush. Bloo Toilet Blocks release foaming cleaning agents and a floral scent to keep bathrooms smelling fresher between cleans. Are they durable enough for regular household use and effective against limescale?

⚡ At a Glance
  • Cleaning Action: Foaming agents released from the cistern travel into the bowl on each flush
  • Best for: Households seeking low-maintenance loo hygiene with less frequent manual scrubbing
  • Not ideal for: People who prefer fragrance-free or chemical-free toilet cleaning options

Blocks sit in the cistern and activate with each flush to deliver cleaning foam and fragrance. An active ingredient helps limit limescale buildup over time.


Continuous bowl cleaning – with intensive foaming action from the cistern

Foaming agents dissolve slowly and are carried by the flush water from cistern to bowl, targeting surface deposits. The foam helps dislodge light soils where water reaches during the flush cycle.

Visible cleaning action reduces the need for daily manual scrubbing and keeps the bowl looking fresher between deeper cleans.

Reduced limescale formation – thanks to an active limescale inhibitor

A specified active ingredient interferes with mineral deposit formation on surfaces exposed to repeated flushing. Regular exposure to the active agent slows scale accumulation on the bowl and flush rim.

Less frequent heavy descaling is required, which makes maintenance easier in hard-water areas.

Long-lasting freshness – with up to 800 flushes per block

Formulation and block density are designed to release cleaning and fragrancing agents slowly over many flushes. Colour release offers a visual cue as the block dispenses its contents.

Extended lifespan means fewer replacements and steady freshness, reducing the effort needed to keep the bathroom smelling pleasant.
