Why is washing machine dispenser draw mouldy?

A washing machine dispenser drawer can become mouldy due to the accumulation of detergent residue, fabric softener, and moisture. These conditions create a damp environment that promotes the growth of mildew and mould. To prevent this, it's essential to regularly clean the dispenser drawer and ensure it's left open to dry after each wash, minimizing moisture buildup. Additionally, using the appropriate amount of detergent can help reduce residue accumulation.
