scrape popcorn off steel pipe

We have a steel gas pipe running along our ceiling about 8'. The ceiling had popcorn removed but the steel pipe still has this coated on the pipe.
Now we have new dry wall hung with a clean finish, but with this ugly pipe coated in acoustic spray.
A contractor advised me to scrap it off and sand it with some sand paper to get most of it off. Then hit it with a can of spray so that it looks smooth and clean?
Can anyone else chime in on this process to get a cleaner look?

Use a wire brush on a drill. Will be a lot faster than sandpaper. Be sure to ware safety glasses as a lot of stuff will fly. Also if you have help a vacuum will help with dust.

Try spaying some water on it and wiping it off.

Can you give me an example of a wire brush, I see the wheel type, cup brush, knotted wire. Is there something you have used that has been most helpful? The pipe is 1 1/4", 8' long. I have an impact drill with a hex bit.
Thanks for your advice.

When was this acoustic originally sprayed on the ceiling? If it was before the late '70s it likely contains asbestos.

Yes, lots of water and let it soak in till it's all soft.

Regardless of what it is or could be...... wear a dust mask and be safe when removing it.

Prior to the early 80s popcorn could have asbestos. Asbestos is only harmful in dry powdering form - where you can inhale the dust. I would assume the contractor that removed the popcorn had it tested if the house is old enough.

If the popcorn wasn't painted - scrubbing with water will remove it. Often when it has paint on it you can scrape off the top and then get it to take water which will soften and remove it from the substrate.
