I started to clean my second little FW the other day. I unscrewed the plate that holds the thread on top of the machine and found what appears to be white grease.
I opened my other FW and it has oil.
The grease isn't in the motor. It on the wheels that turn the machine.
I'm assuming the grease is wrong. I need to know if it matters and do I have to clean it and which one do I clean?
