What’s Actually Inside Your Mattress – And Why Cleaning It Matters

Most people wash their sheets regularly and assume their mattress is reasonably clean underneath. The reality is quite different – and for allergy sufferers or anyone who wakes up congested or with skin irritation, the mattress is often a significant contributing factor.

What Accumulates in a Mattress Over Time

Dust Mites A typical mattress that has never been professionally cleaned can harbour hundreds of thousands of dust mites. They feed on the shed human skin cells that accumulate in mattress materials over time and thrive in the warm, humid environment created by body heat and perspiration.
Dust mite waste particles are a leading cause of indoor allergy and asthma symptoms. They become airborne when the mattress is disturbed – when you turn over in your sleep, when you sit on the bed, when you change the sheets.

Body Oils and Perspiration The average person perspires during sleep. Over months and years, those body oils and moisture work into mattress materials, creating the yellowing and staining that appears on older mattresses. This moisture also creates conditions that support dust mite populations and, in some cases, mould.

Skin Cells Humans shed skin continuously. In eight hours of sleep, a significant amount of shed skin works through sheets and into mattress materials – where it becomes food for dust mites.

Pet Dander If pets sleep on or near the bed, dander accumulates in mattress materials the same way it does in upholstery and carpet.

Allergens from Previous Occupants In rental properties, condos, or homes where mattresses are reused, allergens from previous occupants – including pet dander from pets you’ve never owned – can persist in the mattress for years.

Why Regular Vacuuming Isn’t Enough

Vacuuming the mattress surface removes loose debris and some surface dust mites, but it doesn’t extract the contamination embedded in the mattress materials or neutralize the allergens from dust mite waste.
Hot water extraction reaches deeper into the mattress materials, removing embedded mites, their waste, body oils, and allergens at a level that surface vacuuming can’t achieve.

Signs Your Mattress Is Overdue for Cleaning:
• You wake up with congestion, sneezing, or itchy eyes that improve after you leave the bedroom
• Visible yellowing or staining on the mattress surface
• A stale or musty smell from the mattress
• You or a household member has diagnosed dust mite allergies
• The mattress has never been professionally cleaned
• Pets sleep on or near the bed

What Professional Mattress Cleaning Involves

At From Dark to Light, our mattress cleaning process includes:
Hot water extraction using professional equipment that reaches into the mattress materials to remove dust mites, their waste, body oils, and accumulated allergens.
Anti-allergen treatment that denatures the proteins in dust mite waste, neutralizing their allergenic properties even in residual particles that can’t be fully extracted.
Stain treatment for visible staining from body oils, perspiration, or spills.
Odour elimination for mattresses with musty or stale odours.

Most mattresses are dry within 2 to 4 hours. We recommend cleaning twice a year for households with allergy sufferers, and annually for everyone else.
