Remove Paint from Stainless Steel Pot

All the Bulldogs I have seen are Ali. Great pots, well worth saving.

Have you got a compressor? Sand blasting removes all the paint with ease, sometimes chemical removal methods can leave a residue in the pores of the steel. Just wipe down with brake cleaner after to remove any loose particles.

"Sand" blasting might damage the surface, aluminum is soft. Might work with nut shell medium though.
Known as "media blasting." The modern media is rarely sand anymore.

Common is crushed walnut shell which you can buy in half a dozen grades.
It's even used as traction compound in genuine snow tires.

Besides the respiratory hazard inherent with sand blasting, companies had other suspicions.
There was an argument that the silica sand hit the iron surfaces (frames and engine blocks)
fast enough to combine >>> iron silicate. Which is very brittle and things were breaking.
I don't know if that turned out to be a myth or not.

I use a bit of sandblasting in my job.
Ultra fine Silica.
I also use sandblasting in my hobby ( car resto) and there I have different mediums. Silica is one of them.

Different machines though. The work machine is about 1/100 of the size.

Are you 'sure' it's paint ?
I have a set of aluminium pots that were use on birch fires. Tar burns on black and blacker yet over the years on these. Mine were used as dye baths and simmered for hours.
The thing is though that once the surface soot has been washed off then the black is stable. It's like the coating on old chip pans, which got thick and crusty and didn't go on fire or flake off. The only way to remove that was either elbow grease and brillo pads or to soak for 24 hours in washing soda. Folks just didn't bother, but emptied out the old dripping, cleaned the pot, added fresh blocks and cooked again.
My old dyebaths are definitely not smoothly coated, but the black isn't a problem.

Synthetics blasting media are more common here. Or they were before I left aviation metal work.

I presume you mean your work as a dentist? The most common abrasive media used by hygienists here seems to be baking soda.

Yes. I clean all crown and bridge work, using a sand blaster. Also if I need to recement a brown a bridge I use the sand blaster to remove the old cement.

Yep, I use a baking soda ( flavoured) to polish teeth after tartar removal.
I use a Swiss made system called AirFlow S2 made by EMS. Ship the powder from Switzerland too.

I had to buy a new unit recently. 7 K US when I unpacked it.
Ok if it lasts as well as the old unit. 11 years! Quality!
