Scrubbing Bubbles Toilet Cleaning Gel makes a great bathroom cleaner by preventing the build-up of lime scale and toilet rings. Simply use the dispenser to stamp a gel disc onto the inside of your toilet bowl. The discrete gel disc sits just under the rim. There's no need to touch the disc or the bowl with your hand, making Scrubbing Bubbles Toilet Cleaning Gel less icky than traditional clip-on toilet bowl cleaners. This unique toilet bowl cleaner gradually dissolves with each flush, allowing a controlled release of cleaning solution and fragrance. Each disc lasts up to 7 days, for a 24/7 continuous clean and it leaves no residue behind. Your toilet bowl will remain cleaner for longer. One disposable, easy-to-use dispenser. One gel holder (gel holder contains 6 gel discs).
