Ask Lou: How to prevent moldy smell from vents, clean glass shower doors

Did you turn the air conditioner on in the middle of a heat wave just to find out that it’s making your house smell like mold? Are you unable to get your glass shower doors streak-free?

Home expert Lou Manfredini stopped in to TODAY Friday to answer some of your questions about common household problems.

From smells to squirrels to shower doors, your pesky house problems solved


Thomas O., a viewer from Oakforest, Illinois, wanted to know what to do about the moldy smell coming out of the air ducts when he turns his air conditioning on. With summer temperatures inspiring us to turn those air on high, this is a need-to-know hack.

Lou’s solution? Spray Healthful Home FOG-U Mold Odor Indoor Fogger into musty vents to eliminate any overpowering mold odors. He also suggested using the Healthful Home Mold Magnet for this common problem, as well as a cleaner for the unit’s coil to leave the vents smelling fresh.

Another viewer, Karen L. from Middleton, Wisconsin, wrote, “I was wondering if you know the best way to keep squirrels from getting into my car and eating the wires and nesting by the engine.” Karen has already tried moth balls and wants to know what else Lou would recommend.

Lou said that hanging a rodent repellent inside the engine compartment should do the trick. Some repellents emit an odor that keeps the rats and squirrels away, but is not offensive to humans or pets.
