Sarah said to “create a mixture of warm water and washing-up liquid”.
“Gently lift the seal of the washing machine and use a clean cloth to wipe underneath the seal.
“Spend some time ensuring you remove all of the residue and moisture from the seal,” she added.
“If you want to be more thorough and get into every nook and cranny, add some white vinegar to a cotton bud.
“Then, use the cotton bud to clean all around the underneath of the seal, adding more vinegar as needed.
“After cleaning the seal, run a hot cycle to remove all of the remaining vinegar from the drum.”
