I have a metal link screen suspended by metal rings from a steel rod
right in the front of my fireplace opening. Over the years, it has
become harder and harder to open and close the screen, although I can't
see any rust. If this wasn't a working fireplace, I would just
lubricate it, but most of the lubricants I have are shown as very
flammable on the label. The only exception is some ancient high
temperature grease that is so old there are no warnings on the label,
not even about causing cancer in California.
Should is risk it? It wouldn't actually be in contact with the flames,
but about a foot away. Or is there some other lubricant that would be
better suited? Hate to burn down my house experimenting.
Powdered graphite might do the trick.
Kano labs had some high temperature spray, but it's been
ages since I've seen that. You could sand the rod with emery
cloth, or steel wool. Might help.
Please let us know what turns out to work. My parents have a
fireplace screen. Same deal. Gets hard to open or close.
Spray it on when there is no fire in the fireplace, move the wire
screen back and forth several times, wait 24 hours before lighting the
fireplace. The flamability is most likely the propellant for the
spray so once it evaporates, you should be aok.
Which "it" do you reccomend? Silicone? WD?
Like you say, spray it between fires. My thought is that the
.000001 ounces of liquid you would spray on, won't hurt
anything. 24 hours is perhaps over cautious.
Pay a visit to Manny, Moe, and Jack. (Pep Boys, or similar). Buy a
tube of silicone spark plug boot release. Lube critical parts. Problem
solved. No hazardous sprays, no waiting for cure, low cost. After all,
if it works on the center spark plugs of your 350 Chevy, it will
easily shrug off the more modest fireplace heat.
This is what I use for a lot of things where I want the lube to
stick around in extreme conditions. I've been using it on all
sorts of things and found that those items don't need as much
attention anymore. It's rated for 300°F minimum. The national
chain auto parts stores carry it.
