Time for the washing machine drum cleaning routine again — Dettol drum cleaner, 133 baht a bottle. Normally I pour a whole bottle in every 3-4 months. After the cycle, run it once more with plain water and the drum comes out clean and fresh-smelling. Works on both front-load machines (pour into the detergent and fabric softener compartment) and top-load machines (pour into the compartment or straight into the drum).
