How we chose washing machine cleaner tablets

The best washing machine cleaner tablets fit your washer, the kind of buildup you want to address and the schedule you can keep. We compared tablet count, stated cleaning focus, washer compatibility and use directions.

A larger count may reduce how often you need to restock, but it does not mean the tablets suit every washer or cleaning need. Check the washer manual and product instructions, especially for the right cycle and how often to clean.

Affresh Washing Machine Cleaner, washing machine cleaning tablets
9.7/10Our score
  • Time-release cleaning action
  • One tablet once a month
  • For front-load, top-load and HE washers
  • EPA Safer Choice Certified

See it on Amazon

Pros

  • Monthly use
  • Compatible with all washer types
  • EPA Safer Choice Certified

Cons

  • Not designed specifically for pet hair

Affresh is the easiest fit if you want a clear monthly schedule. The brand says its time-release tablet works through the wash cycle to help power away grime, bacteria and soap scum from internal washer parts.

The tablet is intended for front-load, top-load and HE machines. Affresh also says it is EPA Safer Choice Certified and septic safe, which may help narrow choices for households with those priorities.

Use one tablet once a month according to the brand's directions. If you clean more often because of heavy use or odor, check your washer manual before changing the routine.

ACTIVE Washing Machine Cleaner for Pet Owners: Best for pet hair and odors

ACTIVE Washing Machine Cleaner for Pet Owners, washing machine cleaning tablets
9.7/10Our score

Pros

  • Pet-focused formula
  • Use in an empty washer
  • Septic safe

Cons

  • Twice-monthly routine

ACTIVE's pet-focused tablets are designed for hair buildup, sludge, oil, soap and odor-causing grime. That focus makes this the most targeted choice here for a household that washes pet bedding or clothing often.

ACTIVE recommends placing a tablet in the empty washer, then choosing the Clean Washer cycle or a regular hot-water cycle. Its instructions call for use twice a month, so factor that schedule into how long the pack will last.

The formula is described as using an enzyme blend and as safe for septic systems, HE machines, front-loaders and top-loaders. For other options built around fur, see our best washing machine cleaner for pet owners.

A 24-tablet count is useful if you want a full year of monthly maintenance on hand. The product is unscented, so it may suit people who prefer washer care without an added fragrance.

Choose this option when descaling is part of your goal. If your concern is a specific washer design, compare our best top load washing machine cleaner and best HE washing machine cleaner guides.

  • Oxygen-based formula
  • Targets limescale and residue
  • For HE, front-load and top-load washers

See it on Amazon

Pros

  • 25-tablet supply
  • Targets mineral deposits and residue
  • Simple drum placement

Cons

  • No pet-specific formula

Its directions are simple: put one tablet in the empty drum and run a normal or hot cycle. True Fresh says the tablets work with HE, front-load and top-load washers and are septic safe.

The 25-tablet count gives you a little more than a year of monthly use. That can be convenient if you prefer buying washer supplies less often.

ACTIVE Washing Machine And Dishwasher Cleaning Tablets: Best for two appliances

ACTIVE Washing Machine And Dishwasher Cleaning Tablets, washing machine cleaning tablets
9.2/10Our score
  • 48 tablets for washer and dishwasher cleaning
  • Targets odor and normal buildup
  • For HE and standard washers
  • Washer tablet goes in empty drum

This bundle includes separate cleaning tablets for washing machines and dishwashers. The washer tablets go directly into an empty drum.

See it on Amazon

Pros

  • Covers two appliance types
  • Targets scale and grime
  • Washer tablets use a simple cycle

Cons

  • Requires storing two kinds of appliance tablets

This ACTIVE bundle is for households that want separate tablets for a washing machine and dishwasher. Its washer tablets target odor and normal buildup, including hard-water scale, grime and grease.

For washer cleaning, ACTIVE says to place one tablet directly in the drum and run a normal cycle with hot water. If the washer has a Clean Washer cycle, the brand recommends that setting, followed by wiping the drum, seal and detergent drawer.

Keep the two appliance uses straight: the washer tablet goes in the drum, while the dishwasher tablet goes in the detergent tray. This pack makes sense when you need both types of cleaner, rather than only washer tablets.

  • No chlorine bleach or artificial dyes

Pros

  • No chlorine bleach or artificial dyes
  • Targets scale and odor
  • For several washer types

Cons

  • Smaller pack than most picks here

THE CLEAN PEOPLE highlights a formula without phosphates, parabens, phthalates, chlorine bleach, artificial dyes or ammonia. The tablets are intended to address odor, grime and scale in front-load, top-load and HE washers.

The 10-tablet pack is smaller than most options in this roundup. That can suit a buyer who wants to try a tablet cleaner without storing a large supply, though you may need to restock sooner.

The brand also describes the product as vegan and cruelty free. If your main concern is mold or mildew, choose a cleaner based on that specific focus and keep the washer's own maintenance steps in mind.

What should you compare before buying cleaner tablets?

Compare washer compatibility, cleaning focus and the recommended routine before choosing washing machine tablets cleaner options. A tablet that targets mineral buildup may not be the best match for pet hair or drain odors.

Start with the washer manual for the approved cleaning cycle and any cautions about cleaners. Then look at whether the product is meant for an empty drum, how often it should be used and whether its septic guidance fits your household.

Which washing machine cleaner tablets suit your washer type?

Choose tablets that say they work with your washer style, and confirm the correct cycle in the manual. Affresh, ACTIVE Descaler 24 Pack and True Fresh each state compatibility with front-load, top-load and HE machines.

Front-load washers have door seals that need separate care, while top-load models differ in tub and agitator design. A cleaning tablet handles an empty-machine cycle, but it does not replace wiping accessible areas or maintaining filters as your washer maker directs.

For more detail on front-load choices, read our best front load washer cleaning tablets guide. You can also compare best washing machine cleaner for LG and best washing machine cleaner for Whirlpool options.

Do tablets address odor, scale or pet residue?

Match the tablet's stated focus to the residue you want to address. ACTIVE's pet formula and SHIMMERIX target pet-related buildup, while ACTIVE Descaler and True Fresh call out mineral or limescale deposits.

Odor can come from residue in different washer areas, so no single tablet replaces routine care of the drum, seal, drawer and filter. For a brand-specific comparison, see our Tide washing machine cleaner reviews.

If you're deciding how cleaners work, our guide explains what washing machine cleaner is made of. A separate overview of how a washing machine cleans clothes can help distinguish washer maintenance from detergent's role in a normal load.

How do you use washing machine cleaning tablets?

Use the tablet in an empty washer and follow the specific cycle and frequency instructions. Several products here direct you to place the tablet in the drum, then run a Clean Washer, normal or hot cycle.

Don't put a washer cleaner in the detergent drawer unless its instructions say to do so. After the cycle, wipe away loosened residue if the product directions call for it, and leave the washer open to dry when your manual recommends that practice.

Loading laundry correctly also helps routine wash cycles work as intended. See How to Load a Washing Machine Without Overloading It for care guidance.

Which washing machine cleaner tablets should you choose?

Choose Affresh for a simple monthly routine, ACTIVE Pet Owners for pet-related buildup, or Green Gobbler when hoses and drains are a priority. For year-round descaling, compare ACTIVE Descaler 24 Pack with True Fresh's 25-tablet supply.

The best washing machine cleaner tablets are the ones that fit your washer, target the buildup you care about and match a routine you'll follow. Check your washer manual and the cleaner's directions before the first cycle.
