'Clear instructions on how to clean and oil a vintage sewing machine. Make sure you watch Part 2 for the end result. Provided the machine is not rusty and not damaged this is a straightforward job you can do at home using very basic equipment. Use metal polish on all the steel and chrome, but take care not to get the metal polish on the japanned areas or decals. The decals can wear off if you use chemicals, so they are best cleaned with a little sewing machine oil on cotton wool. This is a Singer 28K dating from 1900, so it is worth the effort.'
I quote from Muv's video write up. I watched all 9 videos she took the time to make. Very good information and yes, you can consider what she does a nice deep clean. If the machine is totally rusted out that is a different matter. I seriously doubt if the average person wants to dis-assemble the entire machine all at once and put it in kerosene soak. This can be achieved in smaller segments and the kerosene or the rust remover can be 'painted' on multiple times until it frees up a section of machine at a time. Much easier to re-assemble.
With the aid of a good manual it can be done a section of machine at a time.
