Need help with discoloration on my Kenmore
I have a model 158.1941 Sears Kenmore sewing machine that is now 39 years old. It is a workhorse and has only needed repair once which was my fault for being in a hurry to finish a corduroy/shearling lining coat for my DH and cracked the bobbin case. Anyway, the side panel where the hand wheel is has turned yellow. That is the only part that has done this, all the rest is the cream color it was when I bought it.
Is there anyway to turn this back to it's original color? Can this part come off or do I need to clean it on the machine? It doesn't cause any problems but just bothers me.
Thanks for any advice you can give.
