Clean and disinfect your toilet bowl — as you remove unsightly limescale buildup — with Astonish cleaning tablets. Just drop into the toilet bowl. Let sit for about 20 minutes. Then flush. Or let it sit overnight for stubborn stains. Rings are gone and your bowl is sparkling clean. Also disinfects at the same time. So much easier than scrubbing and there's no blue water from tank additives. Includes 10 packaged tablets. A must in areas with hard water. Imported.
