But hey, what if you're wondering, can you steam clean a mattress without a steam cleaner? Well, you can, but it might not be quite as effective. Still, with some good old bed steam cleaning, you can breathe new life into your mattress and say goodbye to all those hidden nasties.

Let's get steaming!

Can you steam clean a mattress


Connect your steam cleaner so the water can be heated. Open all the doors and windows in your room to let in the fresh air. If possible, take the mattress outside to be cleaned. Take your sheets and pillows to the laundry and wash them.


Now you can begin vacuuming your mattress. You can use an upholstery attachment, or you can use the vacuum without an attachment.

The majority of dust and debris will be removed from your mattress by vacuuming. Vacuum all crevices and dips in your mattress. If your mattress has a pattern, then you should follow it. Vacuum the sides and underside of the mattress as well.

Make sure you vacuum before steaming. Mould and mildew can grow in your mattress as a result of debris and dirt.


Steaming can now begin. Steam in sections, so you don't miss anything. Don't hover over any area for too long and steam in steady movements. It is important to note that a steam cleaner will make your mattress damp but never wet. Keep an eye on the amount of steam being released.

Steam the sides and underside of the mattress after you have finished steaming the first side. If you are steam cleaning to get rid of bed bugs, a temperature of at least 70-80° C is required. Of course, most steam cleaners can reach up to 100° C, so it should not be a problem.


Be sure to let your mattress dry completely before covering it. It may take up to three hours to dry. Try setting it below a fan if your room doesn't get much air or sunlight. You should set up your mattress outside to ensure it dries quickly.

By pressing down on different areas of your mattress, you can check if it is dry.


Use baking soda to deodorise and absorb any residual moisture from your mattress. Once all the moisture is absorbed, there will be fewer chances for odour.

To deodorise, sprinkle an even layer of baking soda onto your mattress. Leave it to work for 4-5 hours; the longer, the better. After a few hours, you can vacuum the soda. Here is a short instructional video on how to steam clean your mattress.
