sieze up on you and not turn anymore? Like the metal Ateco and Wilton ones? Does anyone know how to "grease" it up again so it will turn easily? I know that just regular W-D 40 or cooking oil just makes it worse? I have 3 of them at work that can't be used anymore because they won't turn. Thanks for any help!

I haven't had it happen to me, but I would think that Pam would work like WD40 and it's food safe, the Pam is. Maybe someone else will know better, sorry.

Don't use pam. It I've heard it will get sticky. Although some people never had problems using it. Sorry I coudn't help.

how about vaseline.........

I would spray it with pam spray. I use pam spray to grease the door hinges here and the squeaky parts on the kids bikes, and haven't had any problems with stickiness. You can also get a silicone spray...I'm guessing it would come from Home Depot. My mom made candles and she had silicone spray for the molds but I remember her using it on cabinet hinges and the pantry track too.

You could also try vaseline.
