Ok so I got all excited about the earlier post about how to clean a washing machine, however I have a front loader and was wondering if anyone has some tips on that? Particularly keeping the water and mould from collecting in the door seal. I find within a few days of wiping it off I get this awful black slimy mould appearing on the plastic seal. It seems to be a bit of a design fault of my (and maybe all front loaders) that water collects here. Help me please!
