I have spent the last year trying to figure out why clothes sometimes smell kind of musty. I bought a lakelands heated airer, I open windows more when drying, I couldn't figure it out. Then yesterday, having done a maintenance wash, I stuck my head in the machine and for some reason opened up the rubber seal inside the door (ours kind of folds over). Its FULL of mould 
It was my first maintenance wash (with soda crystals!), but I wash towels at 60 degrees so there are some hot washes, and I always leave the door open. I am so horrified and can't wash any more clothes till its gone: but there's quite a lot there. We only ever use liquid detergent which I now realise may be the problem. I tried scrubbing at it, and did another wash at 90 with vinegar, and it is having an effect, but I can't see it getting rid.
I can't replace the seal without telling the landlords and I don't really wan't to fork out myself and can't imagine them agreeing to replace. Googling online suggests some people have used dettol mould and mildew, which I already have in the bathroom.... if I put a little on a cloth, then wipe it away immediately, would that be ok? Could it at least shift the worst of it?
I obviously don't want the seal to dissolve but replacing it isn't an option and I feel like I've tried most other advise online.
