HYGIENIX Disposable Pre-Soaked Toilet Cleaning Brush SetYour toilet brush holder is the dirtiest thing in your bathroom. "I never said it out loud, but putting a toilet brush back into a holder full of dirty water always bothered me. Since switching to HYGIENIX, I just scrub with the pre soaked head and toss it straight in the bin no drips, no smell, and my bathroom finally feels genuinely clean." Grinne O., Athlone There's standing water in that holder. Dirty water. Sitting there between every clean.
