Recently, while visiting my mother-in-laws home, which we now own since she has passed away, we noticed that several of the vents have brown spots, most likely rust, on them. It is likely a result of poor insulation on the duct work causing condensation.
My question is has anyone got a remedy for removing the spots.
- I tried Evaporust, which I’ve had great success with in the past on rusted tools and
- Oven cleaner - thinking the spots might be something else
I hear that you can use Kilz on them and then repaint them, but I didn’t want to do this just yet. In fact, I’m more inclined to just replace them entirely.
Of course, I have to address the duct work first.
