Folks- if you haven't tried this yet- please do. It is beyond simple. Don't scrub. Like you are putting moisturizer on your eyelid, like. I am beyond impressed what it has done to the worst looking machine I owned, and just worked over my Davis VF. The bed was so rough it was a challenge to sew with, and now it is quite smooth! Really, really fun! Now, if Glen could just tell us how to do this to our own wrinkles, instead of just our machines, he could make a million bucks! Laura
