What to Consider When Choosing the Best Toilet Bowl Cleaner

Delivery Design

There are three main types of toilet bowl cleaners: gels, capsules, and cartridges.

  • Gel formulas demand some elbow-grease, as well as a toilet brush, which also must be sanitized regularly. Today’s reformulated gels are less harsh but just as effective as always (see the section on formulas below for more details).
  • Capsules offer a less labor-intensive cleaning agent: Simply drop in the tank or adhere to the rim of the toilet to clean and disinfect. Note that tank tablets often contain caustic chemicals (like bleach), capable of damaging the rubber seals inside your toilet over time. A better option is a gel-based capsule that adheres to the inside lip of the bowl.
  • Newer cartridge technology attaches directly to the flushing system and flow pipe. Installation is simple and there are many benefits, including less risk of damage, a deeper clean, and environmentally friendly ingredients.

Formula Factors

Toilet cleaners often arouse the concerns of homeowners who wish to limit their exposure to harsh chemicals. Take bleach, for example. Bleach is a common ingredient used in liquid and capsule toilet cleaners, and though it can kill germs and remove stains, it’s by no means a gentle cleanser. Alternatives to bleach include lactic acid and hydrogen peroxide (oxygen bleach).

Effective Lifespan

A gel cleaner is effective and thorough but must be used weekly to keep your toilet germ-free. Capsules minimize labor time, keeping toilet water sanitized for up to 12 weeks. Installing a cartridge system can keep your toilet germ-free and smelling sweet for up to three months.

Our Top Picks

BEST CARTRIDGE: Fluidmaster Flush ‘n Sparkle Automatic Toilet Bowl Cleaning System

Combining the latest technology with environmental friendliness, Fluidmaster’s toilet cleaning system is a winner on all fronts. Its easy-to-install cartridge injects cleaning solution directly into the overflow tube of the flush valve—a process that can prevent the sort of damage that bleach tablets can cause to toilet parts. Flush ‘n Sparkle cartridges last up to three months and while the new product is not yet graded by EWG for environmental standards, the product does come in a non-bleach version.

The Best Toilet Bowl Cleaner: Lysol Click Gel


BEST CAPSULES: Lysol Automatic Toilet Bowl Cleaner

Simply affix the applicator inside the bowl and the Lysol Automatic Toilet Bowl Cleaner dispenses continuous refreshing action for up to a month. Lysol claims this bleach-free product kills 99.9 percent of germs and viruses. EWG gives it a B grade for health and environmental factors, noting such concerns as artificial fragrance and the presence of sodium laureth sulfate, which poses certain health and safety risks if overused. The results speak for themselves, however. This easy-to-use toilet bowl cleaner does its job effectively, and its effects are long lasting.
