LESLIE: Now we’ve got Tracy in Hawaii who needs some help with gunk on sliding glass door. What’s going on with your sliding-door situation?

TRACY: The slider door has got – it’s got grit in it. And I had sprayed it with something. It was on sale. I don’t remember because I got rid of it. But it’s like real – it hardened, whatever it was. And it’s very hard to – I want to know if I can find something to loosen it. And then what should I use on it that won’t harden when I spray it, to make it easy?

TOM: Well, first of all, what I would do is I would get a really stiff brush and I would try to – I would brush those tracks to try to loosen up all of that gunk on sliding glass door that’s there and then get a vacuum to kind of suck it out of there so that you can kind of get the loose dirt out and the junk out of there. And then what I would spray it with is white lithium grease. It comes in a can, just like WD-40, but it’s not; it’s a little thicker and it stays around longer.

And another thing that you can think about doing is if you can take the door out of the tracks, it makes the whole thing easier. But it’s a bit of a tricky job because – depends on how your door is built. But generally, you can lift it right out of the track. It’ll make the whole thing easier to handle.

TRACY: OK. That sounds wonderful.

TOM: Good luck with that project, Tracy. Thanks so much for calling us at 888-MONEY-PIT.
