Whale oil and 3 in 1 are the hardest oils on sewing machines, and they used to use whale oil exclusively in the sew repair shops.
Muv has some very nice videos about cleaning the vintage machines HOW TO CLEAN UP and use a vintage sewing machine - videos by Muv and Fav grab some tea and enjoy!!!
I wielded my big sledge hammer
on the Touch and Sew I did slamm'er
I gave it a whack
and it sure did crack
and for sure it caused quite a clamor.
