I have a question... I just purchased 4 singers recently and now I need to clean the wood and just wash the machines etc.... Some of them have a funky odor, probably from being in a basement. Anyone have a clue on what to use to wash them from head to toe with? Next will be working with each one to get it looking good but the bath is more important right now. I usually do a light bleach solution on things but kinda afraid to do that on these.. ????
