My UPVC front door mechanism is really stiff, just the mechanism as it's the same when it's open. It's never been great ad we had the stone done outside which threw up a lot of dust so it's even worse now. Reading some conflicting opinions about the correct type of lube to use, some say silicone, some say graphite, there's obviously a lot of dust in there already. Is there any way to clean it first without replacing, and any [more] opinions on what to lubricate it with once it's clean?
