Lube a sticking vinyl window or door

Lubricate vinyl doors and windows
Sticky vinyl windows and doors? Try spraying dry lubricant on
the contact points and wiping it off with a rag. Don't use oil lubricants;
  they can attract dirt, and some can damage the vinyl.

By Alena Gust, a Field Editor from Deer Park, IL. She and her husband, Ray, refer to themselves as Mr. and Mrs. Fixit.

"When vinyl windows and doors don't operate smoothly, it's usually because gunk has built up in the channels. But sometimes even clean windows and doors can bind. Try spraying dry lubricant on the contact points and wiping it off with a rag. Don't use oil lubricants; they can attract dirt, and some can damage the vinyl. Pella recommends Teflon Dry Lubricant.
