A monthly wash with the right machine cleaner can make all the difference to your laundry, tackling hidden grime, limescale buildup, and nasty odours before they cause real problems. But not all washing machine cleaners go deep — some only freshen the drum, while others tackle the full system: seal, filter, pipes, and internal components.
This list ranks the Top 5 full-system deep cleaners available in the UK right now.
We’ve included the best overall performers—even though they may target different issues. These are the ones that clean what matters most in real-world machines.

Verdict
It can be a mine field trying to find the correct product to do the job you want. So we’ve tried to simplify it:
Go for a deep clean product like HG, Dr Beckmann, or Wpro if your machine is smelly, sluggish, or hasn’t been cleaned in a while.
Opt for a lighter descaler like Oust if you’re in a hard water area and want to prevent limescale.
Or choose Pro-Kleen if you want a solid all-rounder that tackles most issues without being overly harsh or too specialised.
That’s as simple as we can put it.
❓FAQs
Do I need to clean my washing machine every month?
If you use your machine regularly, a monthly deep clean is ideal to prevent buildup, odours, and mould. For lighter use, every 6–8 weeks may be enough.
Can I use descaler and deep cleaner together?
You shouldn’t use them at the same time unless the product specifically says so. Many deep cleaners already include descaling agents — check the label to avoid overlap.
