To properly clean a mattress, you should start by taking off the mattress pad, foam, and/or covers. Each have specific instructions on how to clean them, so consult the product’s care instructions and clean accordingly. A handheld vacuum or canister vacuum with an upholstery attachment works best for the next step – vacuuming the mattress to remove any hair, dust, or dirt. Next, spot-treat stains. If you have a pillow-top mattress, it is recommended to use pet-odor remover or carpet cleaner. Sprinkle baking soda over the entire mattress once stains have been lifted. It’s best to let the baking soda sit for 24 hours to ensure cleanliness. Read more about the proper way to clean a mattress.
