Do you know that an average mattress contains 10,000 to 10,000,000 dust mites? Yes, it's true. Yes, it's gross. But there's a way to clean your mattress regularly. Dust mites live in pillows, bed covers, mattresses, upholstered furniture, carpeting, even clothing. One of their favourite place is a mattress. Vacuuming your mattresses every few weeks will help to control the dust mite population. Put approximately 1 cup of baking soda into a small mason jar and add 4 to 5 drops of Lavender essential oil (or your other favourite scent) and give it a shake. This would be enough to do half your king sized bed. Just quickly shake up another batch for the other side. Before you start, it's a good idea to strip off all your bed sheets and wash it in hot water (at least 130 degrees). This will kill the dust mites in your sheets and blankets. While your bed sheet is in the washing machine, pour enough baking soda through a sifter or strainer to lightly dust your mattress with it. Leave on for an hour or more, allowing it time to draw out dirt, moisture, and odor. Using the hose end of your vacuum and an upholstery attachment, thoroughly vacuum the mattress. Vacuum slowly so that you're using the vacuum suction efficiently to pull out as much debris from within the mattress as possible. The baking soda not only draws out moisture and dirt, but it also deodorises and leaves the mattress smelling fresh and clean. The Lavender oil helps calm stress and anxiety and promotes sleep.. Plus it just smells wonderful! Source: http://bit.ly/1w7BS0n
