Things To Consider When Buying A Toilet Bowl Cleaner

When you are in the market to buy a toilet bowl cleaner to get rid of the ugly stains and rings, you will come across many options. If the different brands and models confuse you, here are a few important things that you need to consider:


Just like any other cleaning product, the toilet bowls cleaners also comprise of harsh chemical ingredients such as bleach etc. Although they are good at removing the tough stains and kill germs and bacteria, they are harmful for your kids and pets.

On one hand, there are traditional cleaners comprising of liquids and gels that you apply on the stains and then scrub off with a brush. Some may not need scrubbing. Another style is using pods and discs that you can flush or hand-clean.

Special needs

If you get very hard water in your area resulting in stubborn stains or there are neglected buildups to take care of, then you will need products designed for special needs. Look for cleaners that are powerful enough to meet your specific needs.
