Bathtub mats are often considered a safety item, but if you’re not careful, they can be dangerous, too. Be cautious about what bath and body products you use in the shower; some things, like bath oils or body lotions, can leave the mat slippery or slick. Depending on the bath and shower products you use, you might need to give the mat a regular scrub down or run it through the washing machine, if your mat is machine washable.
When storing your bathtub mat, hang it up if possible. This will keep dust from settling on it if you’re not using it for a while, and keep it out of direct sunlight, which can often have a destructive effect on plastics, weakening them or fading them. If you notice that your mat is deteriorating in any way, discontinue use; make regular inspections part of your routine, and look for small tears, cracks, or powdering of the plastic.
