Q. My daughter lives in Germany, and owns a set of fine china she inherited from her grandmother. That establishes the fact that it is quite old. It is not bone china. Recently she called me and said the china has become moldy, under the glaze. She tried soaking it in straight bleach. It went away but came back. What can she do?

Apparently this is a common occurrence with antique china. I Googled “mold under glaze of china” and came up with a bonanza of suggestions. One of them is this: 1. Mix 1 part salt and 1 part vinegar into a liquid paste. 2. Apply to stain and allow it to sit for 20 minutes. Wash off and check stain. If it has reduced, repeat the treatment every 20 minutes until stain is gone.

Another treatment is to wash with a minimum 30 percent peroxide solution for 20 to 30 minutes. Thirty to 40 percent peroxide is sold in beauty supply stores. Q. I have some nice Melamine kitchen cabinets, easily washable with detergent and water. But simple washing does not take the slight stain from around the handles. What can I use on those stains?

Nothing is easy. For those stains, rub with Mr. Clean Magic Eraser. It will take some rubbing, but they will come clean because the eraser is very slightly abrasive.
