Everyday Cleaning: Most of our mats are washable at 30°C (as indicated in product description) and can either be vacuumed or swept clean with a broom. We recommend on certain mats that a periodic shampooing is beneficial. Stain Removal: Usually a sponge or a cloth with hot soapy water will be sufficient enough for the removal of most stains – for tougher stains such as grease or oil we recommend you to use a dry cleaning product in small amounts. Storage: NBB Matting advises that mats should be laid flat for long term storage. Be careful not to ‘crush’ the matting pile by placing heavy items on top of the mat. Drying: Once your mat has been washed, place it in an inclined position to drain and air dry.
