Most households wash their sheets weekly but never think about cleaning the mattress underneath, even though it's spending every night in direct contact with your skin for years at a time.
What actually builds up in a mattress
Over time, mattresses accumulate dead skin cells, sweat, dust mites and their waste products, none of which are removed by a fitted sheet or mattress protector alone. This build-up happens gradually and invisibly, which is exactly why it's easy to overlook until allergy symptoms or an odour prompt a closer look.
The dust mite connection
Dust mites feed on dead skin cells and thrive in the warm, slightly humid environment a mattress provides overnight. Their waste is a well-documented allergy and asthma trigger, which is particularly relevant for households with young children or family members with respiratory sensitivities.
How often mattresses should be cleaned
A professional clean every 6 to 12 months is a reasonable baseline for most households, with more frequent cleaning worthwhile for allergy-prone family members, homes with pets that share the bed, or after any illness involving sweating or fever.
What professional mattress cleaning involves
Steam extraction cleaning penetrates deeper into the mattress surface than vacuuming alone, combined with a sanitising treatment that targets dust mites and bacteria specifically, rather than just addressing visible marks.
What it won't fix
Professional cleaning won't repair physical wear like sagging or lumps, and very old mattresses nearing the end of their functional lifespan may benefit more from replacement than repeated deep cleaning. We'll always be upfront if a mattress looks close to that point.
Simple maintenance between cleans
Using a washable mattress protector, airing the mattress out occasionally by removing bedding for a few hours, and vacuuming the surface periodically all help slow the build-up between professional cleans.
