Q. Help! Our male dog leaves yellow/greenish spots on our painted walls. These walls are a cream/whitish flat paint and I don't know what to use that will not take the paint off the wall. We live in an apartment and I need to remove the spots before we move.

A. Not sure if I can help here. If your dog has done this repeatedly in the same area, it may have penetrated the paint and may be in the wallboard. About the only thing I might recommend is making a disinfecting bleach solution (3/4 cup Clorox® Regular-Bleach per gallon of cool water) with a little liquid dishwasher detergent. Use a sponge or cloth to apply the solution to the affected area, wear gloves for extended contact, and rub over the area. Check for potential damage to the painted wall by applying a bit to a separate area and looking for paint transfer to the sponge/cloth. It may take more than one application.
