SEW-RETRO GreaseTM has been specially formulated with the proper melting point and lubricating qualities for vintage & antique sewing machines, including the Singer Featherweight 221 & 222K... some attachments need grease sometimes, too! SEW-RETRO GreaseTM is appropriate for any and all sewing machines with all-metal gears. (Do not use this lube with any plastic or nylon gears.)
Each SEW-RETRO GreaseTM comes with an instruction sheet for application as well as a port-cleaning tool so you can clean out the motor ports of the old grease. You can also use a Q-tip or hollow cotton swab (with both cotton swab ends cut off) as a replacement port-cleaning tool.
