Other suggestions from Mrs Hinch fans included replacing the toilet brush every few months, using Zoflora or opting for a silicone toilet brush which is easier to clean.
Sophie Eleanor Jones said: “I put Zoflora in the toilet brush holder and change brushed every few months!”
Amanda Jane wrote: “Dilute bleach in the holder and buy new every two months.”
Lindsay Louise commented: “Clean in bleach every week.
“But throw away every three months and get a new one as they’re not expensive.”
