I had the rather unpleasant job of washing bedding of a family member who had wet the bed - the bedding had been in a bag for 2 days before washing so smelled pretty awful.
I washed it on a 60 degree wash with a biological washing liquid pod in the machine and a cap of the Dettol laundry disinfectant stuff in the fabric conditioner drawer
I did it on a short wash - though that wash still took 1 hour as it was hot water. Took it out - seemed to smell OK - took it to the laundrette, dried it in the dryer at a medium heat. Took it out and when I smelled the dry bedding it still smelled quite bad.
I put it in a machine at the laundrette - again washed it on a 60 degree wash (in the laundrette the longest wash only lasts half an hour) - put a biological pod in the machine - this time dried on the highest heat.
Bedding still doesn't smell right - I've had to bag it up and go home and am now feeling guilty in case I've contaminated one of their dryers.
If it's smelling bad does that mean it's still full of bacteria after having washed twice on 60 degrees and dried on a high heat?
