Try putting Aspirin in the machine to clean on normal wash. I use it all the timeBeen putting cleaning the kitchen equipment off for ages but the washing machine and the self-cleaning oven couldn't wait any longer. The washing machine ran for 90 minutes at 90°c and the oven at 250°c for 120 minutes. The smart meter exploded with delight and I cried.
Use a Paracetamol to clean an Iron (doesnt need all these fancy cleaning stuff)
Oh and I swear by white vinegar to help with general cleaning too
