It seems the rubber seal part of my washing machine is growing mold. I have noticed that often there is water still in the seal after washing. I am trying to dry it out the best I can but still the machine smells horribly. I also keep the door and the washing powder/liquid compartment open between washes, but this does not help either. The good part is that it seems the smell does not affect the clothes, but I really want to figure a way to remove the mold and also to prevent new from forming.
Removing the mold
First of all, check that you're washing machine is bleach tolerable. If it is then run an ordinary empty cycle with hot water and add around 1/2 cup of bleach, bleach is the most effective substance for removing those nasty spores. If your machine is not bleach tolerable then use a considerable amount of vinegar, just be sure to run a quick cycle afterwards to get rid of the smell. You may opt to simply scrub the seal manually with some bleach but running a cycle with some nice hot water will most definitely have a stronger chance of fighting the mold.
Next dab a diluted mixture of bleach into the remaining areas that the mold may be roaming and leave for 10 minutes before wiping down.
Don't always wash on low temperatures
Try to use detergents that contain bleach
Once you're clear of the mold, once a month put an empty boil wash on with some bleach/bleached detergent
The smell is a common result of the mold developed inside washing machines, once the spores have been eradicated then this will no longer be a problem. If there is still an odor omitting from your washing machine in the coming weeks then the spores may have spread deeper and it may be a good idea to remove the seal and scrub underneath.
Sodium bicarbonate and apple cider vinegar are excellent fabric softeners. It is not only that they break the mineral deposits on the clothes, they also have an antimicrobial effect.
It has been some seasons that I've replaced the rubber band. I make sure to collect the water that remains lodged whenever I notice it, but I can't sense any odor. It also used to be the case that loads which I've forgotten in the machine for a few hours would already have a noticeable odor as I hang the damp clothes, but I haven't noticed that either for quite some time.
