We had a 10 year old mattress we wanted to give away but it had a few stains on it and needed a good clean first.
I grabbed some baking soda (aka bi-carb soda or sodium bicarbonate) and white vinegar from the kitchen then got to work. The mattress was looking good as new in no time (well maybe an hour later). Watch the video to see how it's done.
