I have read that some of you like triflow for a lubricant. I have a large 9 needle embroidery machine that has not been used in a while and it seems to be frozen up. Please tell me how you buy the triflow. Is it called lubricant-- how is it packaged-- spray, drip can or what? I have several other machines to fix and those of you who use this stuff seem to be having good luck with the triflow. Thanks for an answer.
