Why don't you give it a go with Vanish or the Labogens. You will have to do it a few times and then finish it off with the Suma
Whether you can tell the difference between this way and that Atomic cleaner you used earlier
The test for clean is you stick your head in after draining the water at the end and you smell nothing.
For years I used to get this mildew smell from my front loader when I did that. It was only after I hit the machine with 5 tub cleans in a row with mops and Vanish that it went away.
You don't need mops in the top loader btw. That is only for front loaders since the water does not reach higher in the tub otherwise.
Until machines are able to do it themselves.
There are LG dryers that claim to self-clean but when dissembled those claims don't quite hold up.
To clean these you have to disassemble the damn things otherwise they will die sooner than normal due to lint buildup and they cost a lot.
Need a better design here. But I don't think there is one in existence
