Anybody use "Soda Blasting"?

[Farmer Dan]

Previous owner painted the heads on my Eldo black.  Tried getting it off with paint remover but that didn't work.  Been looking at getting a soda blaster, anybody know if that is a good idea for this application?  I know my sand blaster would clean it up but it would be too aggressive on cast aluminum.

 Coke or Pepsi?

I made one for $5 that I used to clean some carbs (used old baking soda from my fridge).
Worked great.








Not sure how it will work on paint, it is used when you don't want too aggressive of a media.


If you have a sand blaster, try some of the less course glass or walnut shell.

I plan to buy the HF Soda blaster to do my Guzzi motor in the next few weeks.

A soda blaster probably isn't going to remove the paint you're  talking about.

I have a 40# HF soda blaster, works well. A higher capacity one  I have also works but is more for heavier duty stuff.

A search of soda blaster on WG will show examples.

Use a blaster cabinet if you can, even the sida is abrasive and will go everywhere. Getting it out of where you don't want it can be a chore. Make sure you have a good compressor too.

If you aren't doing a lot of blasting, easier to have someone do it for you. If paint remover can't take it off, unlikely soda blasting will with good results.

Can't imagine this aircraft paint stripper won't do the job.
Stripped a 1996 Ural to bare steel with it.
I first handed the bike to the crew with the acid tanks that do a the cars for restoration.
Their stuff wouldn't remove the paint off 90% of the parts. They tried extra heat and time all too avail. Finally they told me to pick up my parts and there was no charge.

The Aircraft paint stripper did the job. It wasn't magic, but it did come clean and not bother the metal.

  That's because of the hammer forged wrought iron frame of the Ural.

Soda should remove the paint. Soda does not rely on force as much as the soda molecule fracturing on impact and the crystal shard scouring the surface.

I have converted my blast cabinet to use soda, but given how cheap soda media is and that it literally washes down the drain, I just run a simple Harbour Freight siphon spray gun with the feed hose forced into the bottom of a 5 gallon pail of bulk soda and the air inlet hooked up to my air compressor.

Soda blasting is used commercially to remove paint from cars and trucks, even painted fiberglass without damage to the substrate.

Soda is my preferred means of removing paint from pretty much anything and corrosion from aluminum and steel.
