A mop head is a filter. It collects soil from every floor it touches, and if it is put away damp it grows the smell that people blame on the floor. Cleaning it properly is a two-minute job that protects both the mop and the building.
Rinse, wash, dry head-down
Rinse the head in clean hot water after every use, wash it weekly with a laundry detergent or an alkaline cleaner, and dry it head-up so air moves through the fibres. Never store a mop head damp in a bucket: that is where the sour smell comes from.

The weekly wash
- Shake the head out, then rinse it under hot running water until the water runs clear.
- Wash it with laundry detergent or an alkaline cleaner: either in a bucket of hot water with agitation, or in a washing machine on a hot cycle, in a mesh bag so the fibres do not wrap the agitator.
- For a grey or black head, add a bleach-based sanitiser at label dilution and leave it for ten minutes before rinsing. Do not mix it with acid.
- Rinse thoroughly and dry head-up, outdoors or in a drying room, with air moving through the fibres.
Cotton, microfibre and flat mops
| Item | Type and use | Price |
|---|---|---|
| Edco Enduro mop head | Cotton commercial head, 400 g | A$14.00 |
| Sabco cotton mophead refill | Cotton refill, 400 g | A$15.00 |

Microfibre is different from cotton: it holds soil in the fibre and releases it on a hot wash, and it does not tolerate fabric softener, which clogs the fibre permanently. Wash microfibre separately, without softener, and dry it without heat where possible.
Why mop heads go grey or black
Two causes. The first is soil that has bonded and needs the bleach-based soak rather than more detergent. The second, more common in commercial settings, is a head that is being used on both wet floors and general dirt without a rinse, so the fibres are permanently loaded. Where a head goes black within a week of washing, the routine is the problem.
Colour coding and cross-contamination
In any facility with washrooms, kitchens and general areas, mop heads should be colour-coded by zone and washed separately. A single head that moves between a toilet floor and an office floor spreads bacteria and reputations at the same time. The washing routine is also the point at which the colour code is easiest to enforce: one wash load per colour.
When to replace
Replace a cotton head when the fibres are matted and it no longer releases water evenly, and a flat mop pad when the pile has flattened at the edges. On a commercial round, a replacement interval of six to eight weeks is normal for daily use; domestic heads last far longer because they are used less.
Drying and storage between shifts
The interval that matters most is the one nobody thinks about: between the end of a shift and the start of the next. A mop stored in a bucket of dirty water overnight is a bacterial culture by morning, and the smell it produces is what people describe as a dirty building.
The practical setup is a drying rack or a hook in a ventilated cupboard, with the heads hung so air moves through the fibres, and the buckets empty and upside down. In a commercial round, that means the last ten minutes of the shift are for the equipment rather than the floors — which is also the interval where the mop and bucket that go back in the van are worth checking.
Bucket water, and how often to change it
The mop head only gets as clean as the water it is rinsed in, and most floors are cleaned with water that should have been changed three rooms earlier. The practical rule for a commercial round is two buckets — one for solution, one for rinse water — and a change of the rinse bucket at every room boundary, or sooner if it turns grey.
For a double-bucket press wringer that means the head is rinsed in the second bucket and wrung before it goes back into the solution, so the working bucket stays clean all round. It is a slower method than a single bucket, and it is the reason the floors in a well-run building look different from the ones next door.
Questions we get asked most
- What is the best way to clean a dirty mop head?
- Rinse it hot first, then wash with laundry detergent or an alkaline cleaner, and dry head-up. Add a bleach-based soak for a grey or black head.
- How to make a mop head white again?
- A bleach-based sanitiser at label dilution, ten minutes, then a thorough rinse. If it stays grey, the fibre has absorbed the soil and the head is due for replacement.
- What should I soak mop heads in?
- Hot water with a laundry detergent for routine washing, or a diluted bleach sanitiser for whitening. Never mix bleach with an acid cleaner.
- Can you use vinegar to clean a mop head?
- It helps with odour and light mineral film, and it does not whiten or disinfect. A detergent wash plus a bleach soak does more with less effort.
- Can I wash mop heads in a washing machine?
- Yes, in a mesh bag on a hot cycle, separately from other laundry. Do not use fabric softener on microfibre.
