Ecozone Forever Flush 2000 馬桶清潔塊 2入組

I have allergies so I usually dread anything scented near the bathroom, but these blocks are Allergy UK approved and haven't bothered me at all. The water stays blue and fresh for weeks, no scrubbing needed.

These actually last a full month in the tank instead of dissolving in a week like the cheap ones. The water stays blue right up until the block is gone, and no stains building up near the rim. Nice that it's allergy-friendly too since my kid has sensitive skin.

I've been dropping one of these in the cistern every few weeks and the bowl stays noticeably cleaner between scrubs. The blue water makes it easy to tell it's still working, and I like that it's allergy-approved since my skin reacts to harsh cleaners.
