Best Washing Machine Cleaners (2026)

The best washing machine cleaners for odour, residue and maintenance — tablets that keep machines fresh.

Washing machines collect residue that manufacturers' regular cycle never removes — the film that makes a 'clean' washer smell. A monthly maintenance tablet run-through is the standard fix.

No machines were lab-tested by our team; claims come from manufacturer info and owner feedback.

    • Monthly simplicity
    • Descales + deodorises

Buying guide

Follow the label's run cycle — the tablet works when it works through an empty, hot cycle.

Address the root cause alongside: leaving the door open between loads is the #1 way to prevent recurrence.

A monthly schedule plus open-door practice is cheaper than a service call for a stinky machine.

How we picked

We compared washer maintenance products on effectiveness, dose format and value using manufacturer info and broad owner feedback. No lab testing was performed by our team.

Frequently asked questions

Why does my washer smell?

Residue and trapped moisture build the odour — a monthly tablet plus leaving the door open usually fixes it.

How often should I clean the machine?

Once a month is the standard recommendation, more often if odour is a current problem.

Liquid or tablet cleaner?

Tablets are the simplest low-mess option and easiest to schedule into a routine.
