Q. How can I remove rust on outdoor granite steps?
Mix 4 ounces oxalic acid in a quart of hot water and pour this on the granite and let dry. Or scrub with CLR (calcium, lime, rust).
Q. My ventilating fan on the roof has not leaked in years. But with the recent heavy snow, I got a quart of water on the attic floor. Can I prevent that?
If it is only a quart that came from the melting snow, just wipe it up and wait for the next.
Q. I have a gas fireplace. A few chips have fallen off the free-standing ceramic heat shield. Should I replace it?
If the shield is three-quarters or more intact, I think it is safe. Any less, replace it. If you have kept any of the chips, you can glue them back on with Super Glue.
