Clean heating and cooling registers with soapy water and a soft brush.

Heating and cooling registers should be cleaned about once a year, but most people don’t think about them until they have to be removed for something like a painting project.

Begin by dunking them in soapy water. A gentle scrubbing with a soft brush is all it takes to remove the dust and mildew that build up on the louvers. Then rinse them with clean water and be sure they’re completely dry, including the gasket on the back, before you re-install them.

    Thanks so much for reminding us how to take care of our homes. I have a small 2 bedroom raised cottage in New Orleans and I am the one who does (or forgets to do) all the upkeep. These are wonderful reminders that are most often so simple if they are done at the time.

    Thank you for such a fun show and not sanitizing the goofs and you all having such a good time with each other. That is just as important as showing us how to care for our homes!

    Answer to other comment:
    Most registers need periodic cleaning. Air flow over them creates a static charge that makes dirt cling to them. A careful, close inspection, will reveal this. The same can be said of the duct work. I would recommended cleaning them yourself with a good shop vac with high efficiency filters and a brush that’s made for cleaning out duct work.
