Every night I had the bathroom door quickly and to quickly make so that one did not need to hear this nasty squealing noise. Thanks to this wonderful Liqui Moly is now over: D. I've used it about 2 months ago and my door is still quiet. It must be said, this is a small bottle lasts well for many years. (If it's all about a door). I am very satisfied and will probably soon edit the creepy basement door so !.
