Your mattress looks clean. But that's where you rest your face every night.

You wash your sheets every week. And your mattress itself? You never really see it get clean, because what's in it sits deeper than a sheet can catch.

On average, a body loses sweat and skin flakes every night, which build up, night after night, in the fibres of your mattress. Over a year, you're talking about roughly one and a half kilos of sweat that has soaked in. Not visible. Usually not something you can smell. But it's there, every time you put your face on the pillow and breathe for eight hours above what's underneath you.

Washing a mattress cover, vacuuming, airing it out now and then: it feels like maintenance. And it is, on the surface. But sweat soaks into the fibres. Skin flakes are exactly what dust mites live on. Neither disappears by running a vacuum cleaner over it, however thoroughly.

Old assumption: vacuuming once a week is enough to keep your mattress hygienic.

Why that’s not true: a vacuum cleaner removes loose dust from the top layer, but sweat and skin flakes have soaked into the fibres underneath where no suction can reach. New reality: only steam that penetrates deep enough reaches the layer where the problem actually is.

Old assumption: no smell means no dirt. Why that’s not true: sweat and bacteria in the fibres often can’t be smelled until the build-up has been going on for years; the absence of odour says nothing about what is actually in your mattress.

New reality: hot steam that kills 99.9% of bacteria cleans whether or not you can smell anything.

Old assumption: if a mattress feels old or no longer fresh, you buy a new one.

Why that’s not true: what feels "worn out" is usually not material wear but built-up dirt that never came out a solvable problem that gets mistaken for something else

Old assumption: invisible dirt has no effect on your health. Why that’s not true: you lie with your face right above the spot where sweat, skin flakes and bacteria build up for eight hours a night and breathe above it all night long.

New reality: a mattress that is truly hygienically clean also means cleaner air with every breath you take at night.

Old assumption: if you already have a steam device, every steamer does the same thing. Why that’s not true: ordinary steamers leave moisture and loosened dirt behind on the surface and moisture is exactly the breeding ground on which bacteria grow again.

New reality: the Spot Cleaner PRO is designed to also pick up that moisture and dirt, so your mattress is left dry and clean instead of damp.

You wash your sheets every week. Time for what’s underneath to get the same treatment.
