Every now and then, everyone should clean their mattress. I usually do mine every three months. This helps keep the dust mites away and keeps your mattress fresh and clean. When I saw this post on Pinterest to use baking soda, I instantly thought that it was not a necessary step to take. They want you to sprinkle your mattress with baking soda and then vacuum the mattress. Quite honestly, I think vacuuming does the job just fine. The only benefit of the baking soda would be if you have a really stinky mattress, otherwise vacuuming the mattress by itself will do the same job. Vacuuming will keep the dust mites and bed bugs away and keep your mattress nice and clean.
