How do I keep a black plastic clock from staining the wall black?

by Nikki

When we hung a clock with black plastic on back and picture frames with black plastic on back, they stained the wall black. What causes that and is there anything we can do to prevent it?

    I found this...Because I wondered the same for clock in my daughter's room-- "The problem she was describing is called ghosting, or thermal bridging, and though innocuous(harmless) it can be a nuisance. It is helpful to understand why this happens and what can be done to correct it. If you are out looking at houses to buy, you may very well see this. AND MORE If you burn candles or incense, soot may collect along the bottom edge of the frame and leave a blackmark. ... but when it's time to rearrange your space, you might find distracting discoloration in the space where the photos once hung. ... Wipe the wall with a clean, dry cloth before washing to remove any dust or loose dirt.

    Spray the backs with a clear polyurethane spray paint. Two light coats are better than one heavy coat.

    Don't let them touch the wall. Use those little clear bump pads that you buy on a card and are meant to keep the doors of your cabinets from banging into the frame -- you know the ones -- and place them on the backs of wall clocks, picture frames, etc. They will also keep these things from swinging when the doors on their shared wall slam shut.
