Help please!! I would like any ideas on how to fix them to look good as inexpensively as possible. I have had three operations in the last 3 and 1/2 months and am legally disabled but I would like them to be presentable. The builder didn’t put any green board behind them so the rust is the result. Thank you for your time and consideration. I appreciate your help.

  • There is a product called Evapo-Rust. It's a non-toxic rust remover. After the rust is removed, you can repaint your registers, Elaine.

    You would need to sand or brush as much of the rust off. Prime with Kilz primer. Then paint your color. You can use blue painters tape and tape off the wall around them before you paint. My crew and I used regular house paint. Most clients wanted to match the wall color.

    Can you sand them and then paint them? That is what I would do.

    You might try a product called CLR,(calcium, lime, rust) to remove the rust. If that does not work, then I would go to a stiff wired brush, or steel wool, or sand paper. I have never used Evapo-Rust as Anne suggested. It must be a good product, Rustoleum rarely disappoints. Once cleaned up, prime and then paint. I like the idea of matching the register vents to the color of the walls.

    Mine looked bad so I sanded them and then applied several light coats of spray paint. Be sure to apply light coats you don't want this to run and look like a bad paint job. After sanding be sure to wipe the registers down well to remove any dust so you paint sticks well. I used cheap paint from walmart and they still look good (about 3 years later).

    Yep, as mentioned by others here, Rustoleum spray paint would make those look like new again!

    Spray paint I completely agree. It would be recommended to remove the rust first


    Rustoleum recommendations


    PREPARE:

    Always work in a well-ventilated area. Cover the floor and nearby items with a drop cloth. Lightly scuff any glossy surfaces and wipe clean with a lint-free cloth. Use Painter’s tape to hide any surfaces you don’t want to paint.


    PAINT:

    Using slow, back-and-forth motions, spray paint each item with several light coats of spray paint, making sure to overlap each stroke slightly. Apply 2-3 coats of spray paint, waiting a few minutes in between each coat.


    FINISH:

    Let spray paint dry for approximately 1 hour before handling.

    Tip: Use of 2X Ultra Cover Primer in White provides better paint coverage and color.

    Use a product called Navel Jelly it will dissolve the rust. Then get Rustoleum spray auto primer. When dry lightly sand. Then spray with Rustoleum Light even coats. You can use either a metallic or whatever color goes with your decor.

    I would take them off, clean the rust off. One method is to soak it in a plastic container with coke. I've used the generic cola from the dollar store to good effect. Then scrub them and sand or wire brush the remaining rust. Dry thoroughly before painting. I like Rustoleum products for painting metal.

      Glad to be of help! Give it time to soak. My husband used this recently to clean rust off a metal panel. He thought I was crazy when I told him to let it soak overnight, but, is a convert after trying it. He covered it with a garbage bag to keep it from evaporating while it did its thing.

  • You can paint them with heat proof rust safe paint. Just go to the hardware store and ask what you should use.

    Hi Elaine, I'm so sorry to hear about your ops. I hope you're recovering well. I found this video that will show you how to get rid of the rust on your heat registers - https://www.youtube.com/watch?v=FGOduNwX_Mg Hope it helps and get well soon.

    Hi Elaine: You can use Rust-Oleum spray paint for metal to paint the registers. Sand the rusted areas first. An easy way to sand is to get one of those metal bar-b-que brushes. It should fit into the openings. Good luck

    I've used a metal brush and rust remover. Then i use a spray paint primer and then spray paint for metal...they'll look brand new!

    Clean well, scuff with steel wool, then spray paint with RustOleum.

    Use rustolium on them that should work and get a small roller it’s easier.
