Bathmats can become a breeding ground for bacteria such as mildew and mould if they are not cleaned regularly.
The typical location of bathmats make it difficult for them to properly dry off and circulate air, so it is easy to see how bacteria can form on them. To combat the issue, bathmats should be cleaned at least once a week, or potentially more depending how often they are used.
