How Do You Clean a Mattress?
The best way to clean a mattress depends on what needs removing. For routine care, vacuuming the surface and allowing the mattress to air is usually enough. For a fresh spill or stain, deal with it quickly using as little moisture as possible.
Always check the mattress manufacturer's care instructions first. Different mattress constructions and covers can have different cleaning requirements, and some should never be soaked, steam cleaned or treated with household chemicals.
Mattress Cleaning: Quick Guide
1. Strip the Bed
Remove sheets, protectors and other bedding so you can access the entire mattress surface.
2. Vacuum
Use a suitable upholstery attachment to remove dust, hair and surface debris from both sides where practical.
3. Treat Marks
For stains, blot rather than scrub and use only a small amount of an appropriate cleaning solution.
4. Dry Completely
Allow the mattress to dry thoroughly before putting bedding back on. Moisture left inside can cause problems.
Before You Clean Your Mattress
Before reaching for a cleaning product, identify the mattress type and check its care instructions. The safest approach is generally to start with dry cleaning methods and only introduce moisture when the manufacturer's instructions allow it.
Check the Label
Look for washing, spot-cleaning, drying and cover-removal instructions before starting.
Remove Bedding
Wash sheets, pillowcases and protectors separately so the clean mattress does not immediately come into contact with dirty bedding.
Test First
If a cleaning product is permitted, test it on a small, inconspicuous area before treating a visible section.
How to Clean a Mattress Step by Step
Step 1: Remove All Bedding
Take off the fitted sheet, mattress protector and any other bedding. Wash washable items according to their individual care instructions.
Step 2: Vacuum the Mattress
Slowly vacuum the top, sides and accessible areas of the mattress using an upholstery attachment. Pay particular attention to seams, edges and other areas where dust can collect.
Step 3: Treat Stains Carefully
For a suitable stain treatment, apply a small amount to a cloth rather than saturating the mattress. Gently blot the affected area and avoid aggressive scrubbing, which can damage fabrics or push the stain deeper.
Step 4: Remove Excess Moisture
Use a clean, dry cloth to blot away as much moisture as possible. Do not pour cleaning solution directly onto the mattress unless the manufacturer's instructions specifically allow it.
Step 5: Allow It to Dry
Leave the mattress uncovered until it is completely dry. Good ventilation can help. Avoid putting sheets back on while the mattress is still damp.
Step 6: Replace the Protector
Once the mattress is fully dry, use a suitable mattress protector to help reduce future exposure to sweat, spills, dust and everyday marks.
Which Mattress Cleaning Method Should You Use?
| Method | Best For | Main Consideration |
|---|---|---|
| Vacuuming | Dust, hair and surface debris | Safest starting point for routine cleaning |
| Spot cleaning | Small spills and localised marks | Use minimal moisture and follow care instructions |
| Deodorising | Refreshing the surface | Do not rely on powders or fragrances to mask an underlying problem |
| Steam cleaning | Only where specifically permitted | Heat and moisture may damage some mattress constructions |
| Professional cleaning | More difficult or extensive cleaning requirements | Check that the service is suitable for your mattress type |
How to Deal With Common Mattress Stains
Sweat Marks
Regular washing of bedding and the use of a mattress protector can help prevent sweat from reaching the mattress. For existing marks, follow the manufacturer's spot-cleaning instructions.
Drink Spills
Act quickly. Blot the liquid with a dry cloth and avoid rubbing. Use only a suitable cleaning method for the mattress and make sure the affected area dries fully.
Urine
Remove bedding immediately, blot excess moisture and follow the mattress manufacturer's cleaning instructions. If the mattress has been heavily soaked, professional advice may be more appropriate.
Blood
Treat fresh marks promptly and avoid heat, which can make some protein-based stains harder to remove. Always check the manufacturer's cleaning guidance first.
What Not to Do When Cleaning a Mattress
- Do not soak the mattress.
- Do not pour cleaning products directly onto the mattress unless specifically instructed.
- Do not aggressively scrub stains.
- Do not use bleach or strong household chemicals unless the manufacturer explicitly recommends them.
- Do not put bedding back on while the mattress is damp.
- Do not steam clean a mattress unless its care instructions allow it.
- Do not remove a mattress cover if it is not designed to be removed.
Does Mattress Type Affect Cleaning?
Yes. The internal construction can affect how much moisture, heat and handling a mattress can safely tolerate.
| Mattress Type | Routine Care | Cleaning Priority |
|---|---|---|
| Memory Foam | Vacuum and spot clean where permitted | Avoid excessive moisture and allow thorough drying |
| Pocket Sprung | Vacuum and follow cover-care instructions | Protect the fabric and avoid unnecessary saturation |
| Hybrid | Vacuum and carefully spot clean if permitted | Follow the specific manufacturer's instructions |
| Latex | Keep dry and follow care instructions | Avoid soaking and unsuitable chemicals |
| Orthopaedic / Specialist | Follow the supplied care guidance | Manufacturer instructions should take priority |
How Often Should You Clean Your Mattress?
Weekly
Wash bedding regularly and check for spills, marks or other issues.
Every Few Months
Vacuum the mattress surface thoroughly and inspect the cover and seams.
After a Spill
Deal with liquid and stains as soon as possible rather than allowing them to dry into the fabric.
When Needed
Carry out additional cleaning if your mattress becomes visibly marked or develops an unwanted odour.
Do You Need a Mattress Protector?
A mattress protector is one of the simplest ways to reduce how often you need to clean the mattress itself. It creates a removable layer between the sleeper and mattress, helping protect against everyday moisture, spills and marks.
Unlike cleaning the mattress, washing a suitable protector is usually much easier because it is designed to be removed. Choose a protector that fits your mattress correctly and follow its washing instructions.
Should You Air Your Mattress?
Allowing a mattress to air can be useful after cleaning or when changing bedding. Removing the bedding temporarily allows air to circulate around the surface and helps any residual moisture evaporate.
The important point is that airing is not a substitute for cleaning. If there is a stain, spill or persistent odour, identify the cause and follow the appropriate cleaning or professional-care instructions.
