When was the last time you cleaned your mattress?
My mattress was discolored from my dark sheets and a few spills so I decided it was time for a thorough clean! Here's how to deep clean a mattress at home using baking soda and a few other common household items:

- Dish Soap
- Vacuum
- Towel
1. Strip the bed
Begin by stripping your bed of all comforters, pillows, and sheets. Throw them in the washing machine.
2. Vacuum the mattress
After that, vacuum the mattress.
After I vacuumed, I grabbed a scrub brush and went over the mattress one more time before proceeding to get into all of the grooves of the mattress - but this is an optional step.
3. Sprinkle baking soda
Next, grab a box of baking soda and sprinkle it onto the mattress. Use a scrub brush to set in the baking soda & cover the whole mattress. You may use 1-2 boxes depending on how big your mattress is.
Let the baking soda sit for at least 10 minutes. This will deodorize as well as soak up any oils that collect in the mattress over time.
4. Vacuum or scrub
After that, vacuum or use a scrub brush to remove the baking soda.
5. Make a clear dish soap solution
Grab a spray bottle and fill it with water. Add 1 tbsp of CLEAR dish soap. You will want to use clear instead of colored dish soap to ensure that you won't stain the mattress further.
Shake the spray bottle to mix the mixture.
6. Spray the mattress
Next, spray an even coat of the mixture on the mattress. Check for dry spots to make sure it's all covered. You want to make sure the mattress is covered as evenly as possible for an even deep clean & to avoid discoloration.
7. Spray water and hydrogen peroxide
After that, fill a spray bottle with half water and half hydrogen peroxide. Then, spray an even coat of that on the mattress as well.
8. Sprinkle more baking soda
Following that, sprinkle some more baking soda on the mattress and rub it into the two mixtures lightly with a white towel.
Again, make sure the towel you use is white so that no color will bleed onto the mattress.
9. Repeat (optional)
I then sprayed one more coat of the hydrogen peroxide mixture & one more sprinkle of baking soda to make sure it was all coated. But this is optional.
Let the mixture dry. This will take a few hours or overnight depending on how damp the mattress is.
10. Vacuum again
After drying, vacuum or scrub brush the mattress until there's no more residue.
Flip the mattress and repeat if necessary.
How to treat stains on a mattress
This mixture did the trick for my mattress, but if you have any tricky mattress stains you can mix 1/4 cup of hydrogen peroxide with 1 tbsp of dish soap and 1 tbsp of table salt. Spread on the stain and let sit. Scrape off excess with a WHITE rag dipped in hydrogen peroxide.
Finally, add your washed bedding back onto your bed! You can also add a mattress cover for extra protection.

Not a question, but it looks like a mattress pad wasn't being used, which would keep the sheet dye from rubbing off onto the mattress. After all the cleaning, one should really be used. Keeps a better layer between your sweat and the mattress, helping it to stay cleaner.

But mattress pad do not keep odors out completely! I appreciate a way to clean the mattresses in my house! Yes its a lot of work, but worth it if it helps keep the mattresses longer!

A good mattress pad will eliminate this project entirely. There are even waterproof mattress pads. Throwing the mattress pad into a big front loader machine will clean up sweat/stains easily.

would this work for a 4” memory foam topper?
Will this work on a memory foam mattress
Does this work on memory foam? My m f mattress has a fabric cover that's stained. (I eat in bed while watching tv.) No way can I pick up the mattress to get the cover off.
