The lid of a Nikor Professional tank I recently acquired has quite a lot of old chemical residue in it. I cleaned it as best I could with slightly damp paper towels, pushing them as far as I possible into the crevices, but I know there are internal areas I can't reach this way. Any ideas how I might go about removing the remaining disgust? Boiling water and bleach (not necessarily at the same time) come to mind - are there any other things I'm likely to have around the house that might do? I scratch-mix black-and-white chemistry so have all the usual chems in the closet.
