FAQs +
How long does each Sweet Lu block last?
Each block lasts up to 1,000 flushes or approximately 4 weeks, depending on flush frequency. A carton of 12 provides 12-48 weeks of continuous cleaning — typically 3-12 months for most facilities.
How do I install Sweet Lu?
Installation takes 10 seconds. Simply drop the blue block into your toilet cistern (away from the water inlet) and flush once to activate. No tools, clips, or plumbing knowledge required. It dissolves gradually and dispenses with every flush.
Is Sweet Lu safe for septic systems and modern toilets?
Yes. Sweet Lu is formulated to be septic-safe and compatible with all modern toilet cistern types, including low-flow and dual-flush toilets. It contains no harsh chemicals and won't damage plumbing, porcelain, or environmental systems.
How many toilets can a 12-pack supply?
A carton of 12 can supply 1-12 toilets depending on usage frequency. For a single busy toilet (high flush volume), expect 3-4 months. For multiple toilets (office, restaurant, facility), you'll cycle through the pack over 6-12 months. We recommend keeping 2 cartons in stock for commercial use.
Does Sweet Lu prevent hard-water stains and odours?
Yes on both counts. Sweet Lu prevents limescale, hard-water stains, and mineral buildup with every flush. Its deodorising formula eliminates odours at the source rather than masking them — delivering a consistently fresh-smelling bowl 24/7 without scrubbing.
