1. Lysol Automatic Toilet Bowl Cleaning Click Gel

Best Eco-friendly Auto Toilet Bowl Cleaner

If you’re looking for a safe, sustainable option, then this Lysol cleaning click gel is for you. The brand leans towards an environmentally friendly outlook when designing their cleaning agents.

It predominantly uses the active ingredient hydrogen peroxide — a chemical combination of hydrogen and oxygen (3). This is known to be an eco-friendly and more organic option for sanitation.

Hydrogen peroxide is also safer than the harsh bleach chemicals used in many other cleaning agents. As such, this is a fitting product for those particularly sensitive to harsh, dangerous chemicals. It would also work for those with chlorine sensitivity.

If you’re also looking for a cleaning agent with a hygienic application, this is your best bet. The click gel design allows minimal contact with germs. You press the applicator onto the inside of the toilet bowl, and the gel is dispensed hands-free. Customers love that they can then discard the applicator after use, minimizing unwanted trash.

This product sanitizes the toilet bowl with every flush and emits a gentle, deodorizing lavender scent. One application will last a week.

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 (5).

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” (6).

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.

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.

Hands-Free Toilet Cleaning

Household hygiene is important. This is particularly the case with toilet systems. These can be an incubator for dangerous bacteria and other harmful microorganisms.

Less than 1 percent of germs can cause sickness, yet it’s still vital to maintain good household cleanliness (7). This will reduce the risk of germ dispersal.

Toilet systems are fragile, so when selecting an automatic toilet bowl cleaner, be sure to select wisely. Educate yourself on the safety policies of the brand you’re investing in and be sure to check the product’s ingredients. Is it an environmentally friendly product?

Note the design of the cleaning agent and ensure it’s compatible with your toilet system for a hassle-free toilet bowl cleaning solution.
