I was given an old 153w102 singer machine last year it has set in my barn covered but unused, had set on someone's porch for 3or 4 years, I know it did work but I have not plugged it in, it needs new cord and cleaned and oiled, would liked to do this before I plug it in, it may not even work anymore because I don't know how to go about cleaning is, what would I use thanks
