Your steam mop works hard to sanitize your floors, but it can’t do its job if it’s full of grime and mineral buildup. Ideally, you should give it a quick maintenance check after every use to keep your floors spotless and extend the machine’s lifespan.
Cleaning a cleaning tool might sound tedious, but it doesn’t take all day. With just a few simple steps, you can prevent mold, clogs, and bad odors.
Whether you own a Shark, Bissell, or another brand, the maintenance logic is generally the same. Here is the best way to keep your steam mop running like new.
Key Takeaways
- Empty the tank: Always unplug the unit and drain the water tank after every use to prevent mold and corrosion.
- Fight limescale: Use a 2:1 mix of water and white vinegar to clean the tank and dissolve mineral deposits.
- Wash the pads: Clean mop pads immediately after use to stop bacteria growth; never use fabric softener.
- Clear the nozzles: Use a paperclip or safety pin to clear mineral blockages if steam flow weakens.
How to Clean a Steam Mop
We have condensed the maintenance process into six straightforward steps. Follow this guide to ensure your mop sanitizes rather than spreads dirt.
- Time: 25 minutes
- Difficulty: Easy
1. Unplug Your Steam Mop
Safety comes first. Before doing any maintenance, unplug the unit from the power outlet. This is critical for models that automatically generate steam the moment they are plugged in.
Steam is water heated to over 200 degrees Fahrenheit. It effectively kills bacteria, but it can also scald your skin in seconds (1).
If you were just cleaning your floors, let the machine cool down for at least 15 to 20 minutes before taking it apart.
2. Empty the Water Tank
It is tempting to leave leftover water in the tank for next time, but you should avoid this habit. Standing water is the enemy of steam mops.
Leaving water inside can lead to corrosion in the boiler or pump system, significantly shortening the mop’s lifespan. Worse, warm and damp environments are perfect breeding grounds for mold (2).
If mold spores develop inside the tank, you will eventually be blasting them all over your “clean” floors. Empty the tank completely after every single use.
3. Clean the Water Tank
If your steam mop has a detachable water tank, this step is easy. Remove it and wipe down the interior with a clean cloth to remove any slick film or grime.
If you use tap water, you likely have limescale buildup. This looks like a white, crusty haze on the plastic or metal parts (3). The best way to combat this is white vinegar.
Vinegar is acidic and has antimicrobial properties, making it a perfect natural descaler (4).
To descale the tank:
- Mix a solution of one part white vinegar to two parts water.
- Swirl it around the tank or let it sit for a few hours if the buildup is heavy.
- Rinse thoroughly with water.
- Dry the exterior before reattaching it.
Take Note
Steam naturally kills pathogens like E. coli, MRSA, and Salmonella (5). Keeping the tank clean ensures the steam remains pure and effective for sanitizing surfaces for children and pets.
4. Clean the Nozzles
If your mop turns on but releases little to no steam, you likely have a clogged nozzle. This is common in homes with hard water, as calcium and magnesium deposits block the tiny steam jets.
To prevent this, we highly recommend using distilled or demineralized water rather than tap water. This simple switch can double the life of your machine.
To fix a clog:
- Remove the mop head to access the steam nozzle (usually located at the base).
- You may need a screwdriver to remove the base plate, common with Bissell models.
- Use a straightened paperclip or a thin safety pin to gently poke the nozzle hole.
- Twist the pin slightly to break up the mineral calcification.
Some brands, like Shark steam mops, occasionally provide a specific nozzle cleaning tool. If yours didn’t come with one, the paperclip method works perfectly.
5. Change or Wash the Mop Pads
Dirty pads just push grime around. We recommend washing your mop pad after every cleaning session. If you use disposable pads, throw them away immediately.
For reusable microfiber pads, you can toss them in the washing machine or wash them by hand.
Machine washing tips:
- Use a mild liquid detergent.
- Wash on a hot cycle (at least 160 degrees Fahrenheit) to kill microorganisms (6).
- Never use bleach or fabric softeners. Fabric softener coats the fibers and ruins their ability to absorb water and pick up dirt.
If you dry them in a dryer, use a low heat setting and skip the dryer sheet. Air drying is often the safest method to preserve the velcro and microfiber texture. Ensure they are 100% dry before storing them to prevent mildew smells.
6. Wipe Down the Exterior
Finally, give the entire unit a wipe-down. Dust and hair tend to cling to the base of the mop due to static and moisture.
Use a dry cloth to wipe the body, handle, and power cord. Check the area where the pad attaches for any trapped debris. Once it is clean and dry, store it upright in a cool, dry place.
FAQs
How Do You Maintain a Steam Cleaner?
The best maintenance is preventative. Always use distilled water instead of tap water to prevent mineral buildup. After every use, empty the water tank and wash the mop pads. If your manufacturer allows it, run a mix of distilled water and white vinegar through the system every few months to decalcify the internal pump.
How Often Do You Need to Descale a Steam Mop?
You should descale your steam mop every two to four weeks if you use tap water regularly. If you use distilled water, you may only need to descale it every few months. Watch for signs like sputtering steam or white residue on the floor, which indicate it is time to descale immediately.
How Do I Stop My Steam Mop From Smelling?
Smells usually come from bacteria trapped in the mop pads or mold in the tank. Wash your pads with hot water and detergent immediately after use, and never let wet pads sit on the machine. To fix a smelly tank, soak it with a vinegar and water solution to kill the mold spores.
What Cleaner Can You Use In a Steam Mop?
Most manufacturers advise against putting anything other than water in the tank. However, for descaling, white vinegar like Lucy’s Family-Owned Distilled Vinegar is effective. Never put floor waxes, essential oils, or bleach in the tank, as these can clog the steamer and release harmful fumes.
Can I Put Essential Oils in My Steam Mop?
No, you should generally not put essential oils directly into the water tank. Oils can gum up the internal mechanisms and damage the plastic tank. If you want a scent, put a few drops of oil on the mop pad itself, not in the water reservoir.
In Summary
If you want your floors to be truly clean, your tools need to be clean first. Getting into the habit of emptying the tank and washing the pad after every use takes less than five minutes, but it makes a massive difference in performance.
Remember to keep an eye on your steam flow. If it starts to sputter, grab some vinegar and a paperclip to clear those nozzles. With just a little bit of care, your steam mop will be blasting away bacteria for years to come.
