What you see below might look like a clean, tidy bed. But it's got a secret lurking underneath…

…a dirty mattress.

Ok, so I never thought I'd be putting pictures of my stained mattress on the internet – but it's got a purpose, I promise. For our next to last Cleaning 101 series post, I thought I'd share how I occasionally clean my mattresses!

As you can see, it's not terribly dirty – but it could also use a good cleaning. Mattresses need to be taken care of every few months…not only do we all (yes, even you) sweat throughout the night, but you also shed skin and hair in tiny particles. Over time, that builds up in your bed.

As you're about to see, the process of learning how to clean a mattress can be really simple and quick!

How to Clean a Mattress

Step 1: Dust and vacuum.

The easiest (and quickest) way to freshen up your mattress is by giving it a quick vacuum.

We've had this vacuum for years now and it is a cleaning must-have for us. It gets used for little spills, dusting, and yes – even mattress cleaning.

Hop right up on the bed and vacuum it like you would the floor.

Next, sprinkle baking soda all over your bed. Lightly rub it in with your hands so it's not just sitting on top of the mattress. This will absorb a lot of the things that are making your bed stink.

Allow it to set for 10ish minutes, then vacuum up as much as you can. This is a quick way to freshen a mattress if you can't do the next step. I do this (and turn our mattress) every few months!

And don't forget your pillows! If you have pillows that have removable covers, take those off and wash them when you freshen your mattress. If not, throw the whole thing in the wash (or think about whether it's time to replace them).

Step 2: Deep Clean

This isn't something I do a whole lot (because, honestly, I'm not all that concerned about stains on my mattress – nobody ever sees it). However, it is nice to do this once a year or so to really get your mattress as clean as possible.

I talked about this beauty in my upholstery cleaning post a few weeks ago – it's another one of my favorite cleaning supplies. If you have kids or pets, you need this carpet/upholstery cleaner in your life.

As a carpet cleaner (and in so many other places in my home), I use this cleaner. It's available at Dollar Tree and it's one of my favorite cleaners of all time! I normally dilute it for everyday cleaning – I use it undiluted in the carpet cleaner.

If you have any urine stains, this is a great product to pretreat with. It has saved me from the worst pet accidents and works incredibly well on stains.

I'll also usually pretreat stains with regular foaming carpet cleaning (nothing special, any kind will do).

After allowing those to set in for a few minutes, let the upholstery cleaner do its magic. If I'm just spot treating, I'll use the smaller attachment (that comes with the carpet cleaner) to knock out little stains.

Usually though, I'll drag the whole thing up on the bed to clean. It honestly takes about as much time as spot cleaning, and with spot cleaning, you'll often find that the area around your spots is dirtier than you think (making for some funky looking reverse stains and dirt rings).

You'd clean it just like you clean carpet – once over with the wash function (using the Totally Awesome cleaner I mentioned above) and once over to rinse. As you clean, make sure you go back over without spraying a couple of times to suck out as much water out as possible (if you'd like to sleep in your bed tonight, that is ๐Ÿ˜‰).

It's incredibly effective at knocking out stains, as you can see above. This is only something I do maybe once a year though – it just takes awhile to dry, so it's not something I'd put on even the monthly cleaning schedule. If you do this, I highly recommend doing it in the morning so your mattress has plenty of time to dry throughout the day! Using fans to dry it also helps.

Step 3: Turn your mattress.

This is also a step I do every few months. If possible, turn your mattress both horizontally (so the head is now at the foot) and vertically (so the top is now on the bottom). Make sure your mattress is dry before turning top to bottom. Our mattress is only made to turn horizontally, so we do that to make sure weight and wear is distributed evenly.

And just like that, no more dirty hidden secret underneath! Learning how to clean a mattress can make a difference in smell, look, and just general maintenance of your mattress…we all want to get more miles out of our big investments, and this is a sure-fire way to do that.

  1. Can you clarify what type of mattress you have? Is it a regular one OR temperpedic/memory foam?

    1. We have the one on the site that’s called “Cool Gel 2.0 Mattress.”

  2. Hi Leslie,
    I do vacuum my mattresses from time to time, but I’ve never thought of taking the carpet cleaner to them. Thanks for the great idea! I do find that a great mattress cover goes a long ways towards keeping mattresses from getting icky. I love bamboo mattress covers, because they are awesome at protecting from spills and accidents, but they are breathable and quiet, unlike old school plastic covers. ๐Ÿ™‚
