With the Glorix Active Blue Water Ocean toilet block, your toilet stays clean and fresh with every flush. The block produces blue water that not only smells great but also cleans effectively. You'll immediately see your toilet being cleaned. The formula creates foam and helps prevent limescale buildup. The block is up to three times more effective against limescale than conventional toilet blocks without blue water. This keeps your toilet clean longer, even between flushes. The holder is 100% recyclable, so you're also making an environmentally friendly choice. Simply place the block over the toilet rim, ensuring it works effectively with every flush.
