Q. We have a fridge that is tightly wedged between a countertop and a room dividing wall. There is about a ½-inch space next to the wall, and zero clearance against the waist-high countertop. There is plenty of room in the back .

Mold is growing on the wall that is ½-inch away from the fridge. We’ve pulled it out a couple of times and cleaned, but it is an ongoing problem and is destroying the paint and wallboard. Can we clean the wall again and put some kind of mold-proof surface on it to prevent further problems? Or should we buy a smaller fridge and slide it into the space, with a newly repaired wall?
