No. Definitely not! My machine never has any issues with mould and I could do without adding more chemicals to my environment. Also I’m not sure that typical disinfectants are very effective against that kind of mildew like stuff anyway.
Run your machine on a hot wash, full of towels once in a while and the problem simply doesn’t occur in my experience.
Also from what I can see some machines are more prone to it than others.
The other issue seems to be using cool / lukewarm washes and certain eco detergents that are practically food.
In terms of laundry hygiene, in normal residential laundry there aren’t any issues with bacteria or viruses that will survive a normal wash cycle. Hospital laundry is an entirely different issue due to the possible presence of high risks and systemically eliminating very hospital specific risks like Clostridium difficile (C. diff) and MSRA that are problematic in healthcare settings with lots of people around, many of whom may have weakened immunity.
As described above the usual approach is barrier washing machines. The machine is usually part of a wall between two rooms. One side is the “dirty” area and the other is the “clean area.” The two don’t get cross contaminated. Clothes / bed linen are loaded by staff wearing full PPE on one side. The machine completes a full cycle to sterilise them and they are taken out by staff on the other side who can then handle them as clean, processed linen - they can be tumble dried, ironed etc as normal clean laundry.
This machine is used in a lot of health care settings here where they’ve a need for local laundry:
You can install several side by side for bigger facilities but they’re an ideal size for handling a specific facility locally like a high risk ward or a care home. They also have cycles and chemicals for very specific risks.
They usually have other building precautions too like air pressure differentials, double air locked doors and a lot of staff protocols aims PPE etc
The data logging is a big deal for quality management as they can keep record of exactly how each cycle performed.
Automated bed and trolley washers, a bit like giant dishwashers, are also becoming a lot more common.
