• KOBAYASHI Toilet Cleansing BLUE is a "long-acting automatic toilet cleaner" designed for hassle-free toilet hygiene. Its key highlight is the blue-colored cleaning water released upon flushing—a visual indicator of effective cleaning. The slow-dissolving formula lasts up to 300 flushes (about 1 month of daily use), effectively removing limescale, urine stains, and dirt, while inhibiting common bacteria like E. coli. It emits a fresh, mild fragrance to mask unpleasant odors, leaving the bathroom smelling clean.
• The pH-balanced formula is gentle on ceramic toilets, pipes, and septic systems (excluding ultra-sensitive ones). Its compact, easy-to-use design requires no manual scrubbing or complex installation. Suitable for homes, offices, hotels, and other spaces with toilets, it simplifies daily cleaning routines and maintains long-term toilet freshness. Ideal for busy individuals seeking efficient, low-effort cleaning solutions.

1. Unpack: Open the packaging and take out one cleansing block; avoid touching with wet hands to prevent premature dissolution.
2.Install: Place the block in the toilet tank, away from the water inlet and flushing mechanism to ensure normal flushing.
3.Activate: Wait 10-15 minutes for the block to start dissolving; the first flush will release blue cleaning water.
4.Use: Each flush automatically cleans the toilet bowl, removes stains, and freshens the air with blue water.
5.Replace: When the block is fully dissolved or the blue color/fragrance fades (after ~300 flushes), replace with a new one.
