Here are some maintenance tips to help you out:

Strip

When cleaning your mattress, strip it down so that you can check it for surface stains and soil. Use upholstery shampoo or a diluted mild soap to remove the dirt or stains. After cleaning it, let it dry completely before covering it up again.

Flip or Rotate

Every season, change the position of your mattress to avoid sags. Flip it over, rotate it by turning the foot so that it becomes the head. Doing this will allow the mattress to wear more evenly, thereby minimizing sags, because you won’t be sleeping on the same portion or side all year long. Contrasts in firmness and softness will also be minimized.

Give it Some Sun

The sun possesses the power to disinfect. Locating your bed where it can receive direct sunlight in your room will help remove germs and bacteria. When spot cleaning, be sure to expose the mattress to the sun for a while before turning it over.

Change Sheets

Dust mites evolve from dirt that collects on your mattress. To avoid mites, change your sheets regularly, once a week if possible. This way, the dirt that’s difficult to remove will not form a more fertile breeding ground. Vacuuming the mattress, meanwhile, is another way you can keep dust mites from collecting on your bed.

Use a Mattress Cover

A mattress cover is essential to protect your bed from dirt and dust mites. With a cover, you won’t have to worry about the entire mattress becoming dirty or stained. Instead, you can easily remove and replace the cover should you spill your morning coffee. There are also covers that fight off dust mites, so it’s better to use them for added protection.

Stores selling mattresses near San Diego can assure you of durability and quality. However, it’s still your responsibility to maintain and keep them clean. Doing so will help your mattress endure.
