Be warned, I did this after seeing a thread on mn and my washing machine broke. It went into one at the sudden shock of being asked to do a hot wash and then in my frustration I ripped the door handle off. Should you need it I can recommend a company that do next day delivery of washing machines and will deliver on a Sunday.
You can get limescale removers that can be used in your washing machine too.But need to check the packaging.There are also specialist washing machine cleaners but I forget the names.Obviously don"t use at the same time as washing soda!
I did this last week - there must be nothing good on telly at the moment or something?!
My wash was 1. a boil wash with half a bag of soda crystals (green bag from Waitrose cleaning aisle) 2. Scrubbed out gunky drawer with toothbrush and a bit of fairy liquid, plus boiling water from kettle 3. Wiped around the rubber seal with a cloth then more digging with a toothbrush, really gross and pulled out old hairpins and lots of black grot, so followed with 4. A 60 wash with vinegar in the drawer 5. Wiped out the inside and the door with a wet cloth to get any remaining bits of black gunk from door before using it for a normal wash.
I also tried to open up the bottom of the machine but it was all screwed too tight. My above plan got rid of the 'fusty' smell that had developed while we had been away on holiday anyway.
