Soda blasting case question
 

In the past, I've soda blasted my 3.2 intake that was powder coated. It took a ton of media to complete, but was happy with the results leaving a nice, clean, natural looking aluminum.

Anyways, was wondering if soda will take the hard-coated corrosion off my cases with minimal effort?

Meaning, will it clean this corrosion at all? If so, will 1 - 50lb bag of soda do it? More?

I didn't neutralize the caustic chemicals in Easy-Off the first time I cleaned the cases, and the next day, it developed a thick layer of corrosion. The cases looked brand new the day I did it though. Very disappointed and was a learning lesson for sure!

See photo for reference.

Reason for the question is, is I have to drive 2 hours away to use my fathers blaster and would hate to waste my time and money if it can't be done reasonably.

Trying to plan ahead.

Whatcha say PP braintrust???? Anyone done this?

The outcome with soda is more dependent than glass on the pressure at the tip and the size of the tip and the cfm of the compressor. In my experience a little 3hp 9-10 cfm comp. will give marginal results. I have 8hp of compression (two comp in parallel going into one 60 gal tank) and I use a med tip gun from tptools and I run 110 psi to the gun. I get good results with that set up but it def. takes longer than with glass. Now I'm talking a siphon gun, the kind you see in a cabinet. If you are talking a pressure gun like is used outside with a pressurized tank that holds the media you will get better results than with a siphon gun. What size is your Dad's comp? 50 lb should do it.

There are a couple different grades of soda but boosted is right. It really comes down to cfm's I wouldn't even bother if you can't get a hold of a good compressor. Look in your area for someone who does dry ice blasting. It will run you $150 to $200 but well worth it if you can't find a worthy compressor.

Let's just say I have enough compressor to drive a small factory!

1 large body shop industrial horizontal-tank compressor daisy chained to 2 - 80 gallon tank with 2-stage compressors.

My dad's resto shop doesn't run out of air. :)

!!!

:eek:

If you have any soda left over you can use it as toothpaste..

I bet that JustTheTIPpy is thinking that blasting soda won't cut it with regard to cleaning my trap - probably need industrial bleach, or sulfuric acid, or both !!!

Lol

Rawknee I think you need to try some oven cleaner..

I think the oven cleaner might put itself right back in the can!!!

A buddy of mine has a older mag case engine he is about to rebuild. It has a little corrosion inside the case and grime that is baked on. Would it be safe to use soda or even dry ice on the inside of the case?

Those are the 2 best media's to use...

Make sure to flush the oil galleys well afterwards if using the soda.

will do

Do a search of 'vapor honing technologies' - it appears to be a great alternative to dry blasting...

^ gawd that looks great!

Those look brand new!

Looks like it's still an abrasive blasting though, so you don't get the benefit of not having any abrasive grit in your engine, which seems to be the point of soda blasting (?)

Exactly... my local vapour blasting plate declined to clean our engine case as it uses tiny glass beads and these would get inside oil galleries etc...
