OK, this is going to seem like a total newbie question, well, because it is (for this kind of thing anyway), but.....

Is it at all possible to process Colour film (either positive or negative) in B&W Chems (I am currently using Ilford LC-29)? What kind of results would I expect? Would it contiminate chems (such a Fixer), that I wish to keep and re-use for B&W processing?

Any advice would be great!
