Ergonomic mats often come with instructions on how to clean and maintain the item. There are specific things though that you need to avoid when caring for the mats.
For one, anti-fatigue mats should be cleaned only with mild cleaning agents and water. Harsh brushes should not be used on the mats.
The mats should never be left exposed to direct sunlight as well. Let the mat dry properly after a clean-up.
To guarantee that you will have an ergonomic mat that lasts, always get a product that suits your purpose appropriately.
