Who owns these washing machines and dryers? Are they common property, but you have to plug them into your unit’s power point in the laundry to use them?
If they are CP, who services them? Are these odours the result of the lint filters not being cleaned out regularly, or other lack of maintenance? If the filters are not being cleaned, this is also creating a well known fire risk.
Without intending to be flippant, perhaps you could take a bucket of hot water from your unit and put it into the washing machine. Most current detergents work quite well in cold or warm water anyway.
