Q.I want to lighten the color of 15-year-old cedar paneling that has darkened with age. The wall paneling consists of 3/8x6-inch tongue-and-groove clear cedar installed over 1/2-inch drywall. I took a sample of the interior cedar and experimented with a bleaching method I often use outdoors. I applied a solution of diluted household bleach to the cedar, followed by flushing with ample amounts of water. The results were quite satisfactory, but the procedure obviously won’t work indoors.

A . Corresponding Editor Paul Fisette responds: I think that if your normal bleaching procedure accomplished what you want, then you should try to use a modified version of the same procedure indoors. First, wet-sponge the bleach solution (50/50 household bleach and warm water) onto the boards, and wait for the boards to lighten up. Then go over the boards lightly with a sponge that has been dampened with clean rinse water, instead of hosing the wall down. It would be a good idea to test this procedure in an inconspicuous corner of the room to be sure the result is satisfactory.
