Washing Machine Tub Cleaner Usage Guide: Smells Bad?

Have you opened your washing machine expecting fresh laundry, only to be hit by a musty, sour smell instead? If your clothes smell fine going in but come out with an odor, the problem usually isn't your detergent; it's what's building up inside the drum itself. A good washing machine tub cleaner is designed specifically to tackle this, and understanding why the smell happens makes it a lot easier to fix for good.

Why Washing Machines Start Smelling Bad in the First Place

Every wash cycle leaves behind small amounts of detergent residue, fabric softener buildup, and moisture in areas that don't fully dry between uses the drum seal, the detergent tray, and the inside of the drum itself. Front-load machines are especially prone to this because the door seal traps moisture after each cycle, creating a warm, damp environment where mould and bacteria can grow. Top-load machines aren't immune either leftover residue can build up along the drum's inner walls over time, even without a rubber door seal trapping moisture the same way. Left untreated, this buildup is what causes that musty smell to transfer onto otherwise clean laundry.

Signs Your Washing Machine Needs a Tub Clean

A musty or mouldy smell inside the drum, even when empty
Clothes smelling slightly off despite using enough detergent
Visible black or grey residue around the door seal or drum edges
A smell that lingers even after running an empty hot wash
Slower draining or a faint smell coming from the drain area

If any of these sound familiar, it's a sign residue has built up beyond what a normal wash cycle can clear on its own.

How Washing Machine Tub Cleaner Works

A washing machine tub cleaner is formulated to break down detergent film, fabric softener residue, and mould or bacterial buildup on the internal surfaces of the drum areas that regular detergent doesn't fully reach or clean during a standard cycle. Run through an empty cycle, the liquid works through the same wash mechanics as a normal load, but targets the internal drum walls, seals, and crevices rather than fabric. This is a different job from your machine's built-in "tub clean" cycle, which uses hot water and agitation but doesn't include a dedicated cleaning agent pairing the two together is usually far more effective than either alone.

Front Load vs Top Load: Does It Matter How You Use It?

The core process is similar across both machine types, but there are a few differences worth knowing:

Front load machines: pay extra attention to the door seal, since this is where moisture and residue collect most. Wipe it down after the cycle completes, and leave the door slightly open between washes to let it dry out.
Top load machines: buildup tends to concentrate along the drum's inner walls and agitator (if your model has one), so a full empty cycle with the cleaner is usually sufficient without extra manual wiping.

In both cases, always run the tub cleaner on the hottest available empty cycle for the best results.

How Often Should You Clean the Tub?

For most households, running a washing machine tub cleaner once a month is enough to prevent buildup from becoming a persistent odor issue. In humid climates, or if you frequently wash on cooler cycles (which don't kill bacteria as effectively as hot washes), every two to three weeks is a safer interval.

A Practical Tip From Real Use

A detail that's easy to miss: running the tub cleaner once doesn't undo months of buildup instantly, especially in machines that haven't been cleaned in a long time. If the smell persists after the first cycle, running it a second time within the same week rather than waiting a full month clears residual buildup far more effectively than a single cycle alone.

Frequently Asked Questions

Why does my washing machine smell even though I clean it regularly with detergent?

Regular detergent cleans clothes, not the internal drum surfaces. A dedicated tub cleaner targets residue and mould buildup that standard washing doesn't reach.

Is tub cleaner liquid different from my machine's built-in tub clean cycle?

Yes. The built-in cycle uses hot water and agitation, but doesn't include a cleaning agent. Using tub cleaner liquid alongside that cycle is more effective than the cycle alone.

How long does it take for the smell to go away after using tub cleaner?

Most machines smell noticeably fresher after a single cycle, but heavily built-up machines may need a second cycle within the same week to fully clear the odor.

Can I use tub cleaner liquid on both front load and top load machines?

Yes, the core cleaning process works for both, though front-load machines benefit from extra attention to the door seal after the cycle completes.
