Best Automatic Toilet Cleaners of 2020

Edited by Sensible Digs
Effective toilet bowl cleaning starts here.

Household cleaning can be daunting — even more so when you lack the proper tools or products necessary to get the job done. Choosing the right products will simplify the task in hand. There is no exception when it comes to toilet bowl cleaning.

Statista tells us that the U.S. global household cleaners market value comes in at 31.19 billion USD (1). The popularity of toilet cleaners is rising at an approximate compound annual growth rate (CAGR) of 5% (2).

Yet, with so many available options, it can be a challenge to select the right product for your toilet. These are delicate installations and must have the proper care provided.

How to Find the Best Toilet Bowl Cleaner

There are many criteria to look out for when making this decision, such as:

Safety Is Important — Read the Warnings

Safety is a priority. Be sure to pay attention to the ingredients of the toilet bowl tablets you’re purchasing. Many are constructed of harsh and possibly toxic chemicals. TheOrganic Consumers Association warns of an increase in air pollution caused by these types of cleaning products (3).

A study was carried out by the Integrated Environmental Assessment and Management team. It found that 72% of polymers in U.S. household cleaning products contained “adequate environmental fate and hazard data” (4).

Look for a toilet bowl tablet that is free of chlorine bleach. This will usually be found in liquid or capsule toilet bowl cleaners. Going bleach-free will minimize the risk of harm to those with chlorine sensitivity. Seek kinder ingredients such as hydrogen peroxide or lactic acid.

Products marked with words such as “danger” and “hazard” will usually be most actively harmful, so watch out.

Eco-Friendly — Choose the Environment!

By choosing the right, eco-friendly products, you can help reduce the pollutants being emitted into the atmosphere. So, go eco-friendly.

Opt for tablets containing ingredients kind to the environment. This will both minimize harmful pollutants admitted into the air, and be suitable for those sensitive to harsh chemicals. Eco-friendly compounds are also more likely to be suitable for septic systems (5).

Design — What Will Work for You?

  • Gel formula: A gel formula coats the inside of the toilet bowl upon application. This will ease up rigid grime, allowing for a smoother removal of dirt.
  • Capsule form: Automatic toilet bowl cleaners can come in capsule form. Also known as drop-ins, they provide a swift solution for those who hate to get too close to that grime. Capsules are dropped into the toilet tank, cleaning and deodorizing the toilet.
  • Cartridge technology: If you’re looking for a less time-consuming cleaning agent, opt for a cleaner that uses cartridge technology. Installation is easy, and this design can last for months before a replacement is needed.

Top Tip

Be sure to read the product information before purchasing. Some emit a blue dye with each flush — a design that may please some and frustrate others.
