Has anyone every pulled out the detergent tray in a front loader? Don't like what you see? Washing machines if not cleaned regularly can end up with black mould and bacteria build up. I have a process on cleaning my machine that is super simple and chemical free. With the amount of washing I do I like to conduct this clean once a month. Necessary in my household)
I start by puling out my detergent dispensing tray and place it in warm soapy water (dishwashing liquid is fine). I use an old dish brush to give it a good scrub then let it soak. Alternatively you can put these in the top rack of the dishwasher, but I have never tried. I then use the same brush or an old tooth brush with washing up liquid or white vinegar to thoroughly clean the drawer area. You will be shocked at what you find!
Once this is clean and dry I place the drawer back in. Then add 1/2 a cup of white vinegar and 3 tablespoons of bicarb soda directly into the drum, and run it on a hot cycle. Once this is done wipe around the opening of the machine with a sponge and get rid of any marks or built up grime and you're done!
All of the above can be purchased at most supermarkets.
