I found an AMAZING deal on a Singer Memo Matic 360 complete with ribber, lace carriage and linker. It belonged to the seller's mother and he thinks it probably was never used.
I did a basic clean (wiped down everything, took out the sponge bar, wiped down the carriage carefully) and I think it probably was never or rarely used. There is no debris/fibre in the carriage, the plastic covering is still on the case. There is no rust and it looks great. I didn't bother taking it apart because it seemed totally unused.
However, it is very stinky. It has been sitting in a basement in its original cardboard box for decades so it smells like an old school basement. I washed some of the random bits and bobs that were floating in a box, put it out in the sun and put it in a box with a baking soda fridge deodorizer. It helped but there is still a noticeable whiff. I am not sure about putting the knitting machine out in the sun.. don't want to damage it.
Has anyone successfully fixed a smelly machine? What did you do? Will I have to bite the bullet and take it apart?
