Soda Blasting-A Less Messy Alternative To Sandblasting?
Posted by: UGLYTRUK ()

I need to sandblast the battery tray area on my 62 Spyder, and the inner rear fenders on my 65 Monza. Obviously sandblasting makes a huge sandy mess, I just did the windshield frame on my 1984 Suburban, whadamess. Is soda blasting just less abrasive and you end up with a baking soda mess?

Yes, but the soda you can wash away with water.....

May not penetrate the paint they used on the battery tray, if there is any left

Today We had a hard time getting the gloss black paint off the headlight mounts. We had to scrape it first to remove the top layer then bead blast went fairly easily at 100 psi and 11 cfm.

I found soda blasting to work well for getting carbon off the tops of pistons. However, like Al said, I don't know if it'd be abrasive enough for the battery tray. Only one way to find out!

I have a medium sized pressurized "Sandy Jet(?) sandblaster. Do I just use the soda instead of sand? My nozzle is maybe 3/16". And there is zero paint in the battery tray area, just light to medium rust. Presumably the soda is far less abrasive then the sand/black beauty product I use. It resembles beach sand, rather fine. I buy it at Tractor Supply.

I had to buy a soda blaster setup. Different nozzle due to media difference. You would have find a way to slow down the delivery of the powder. Most sandblsster guns are 15 cfm, which would use up your soda fast.

The HF unit I bought (with 20% off coupon) has an adjustable nozzle from 0 to 8.5 cfm. It worked great cleaning the Mouse House 110 engine.

You may find that for an equivalent amount of cleaning, that simply turning down the pressure for the nozzle and using sand ends up with less mess than higher pressure and soda (or some other lighter media), as you might not have to keep going over the same area with the heavier sand. Years ago, I sand blasted part of my rear fender on my "other" Spyder using a aircraft mechanic's sandblaster, and he did turn the pressure way down. It took hardly anytime at all to strip the rust with NO warping and the mess was minimal. I was surprised at how easy and quick it was to do it like that, and how little mess there was afterwards. Something to think about!

I have 2 blasting cabs, big one at the ranch has coarse grit for heavy rusted steel parts and the soda blast cab is for delicate aluminum parts, work great for carbs, even the floats shine, I blast all the aluminum Corvair stuff in the soda, engine cases and PG trans cases.

I have "turned down" the sandblaster as my small air compressor runs out of air. I guess I'll have to try the soda blasting. Do I need a different nozzle? Does it not cake? In the tank...

You need a compressor that can deliver. A 4.0 cfm compressor will disappoint as it will not do the job as it can't keep up. A 8.5 will be adequate in most cases. Tank size is also a factor. 15 gallon not do any good blasting. 29 gallon or better.

Find someone with a big compressor who can help out, if you don't want to invest in the right compressor.

Or be very patient and do small blasts and let compressor catch up each time you blast.

I just recently sandblasted the area in the far rear inner fender area on the LM. It's to tight to grind anything there. Used a hopper type HF gun with their 80 grit glass. Considering it was in my shop on the lift the mess was manageable. Worked pretty good as well. Photos of after sanding and grinding, rust paint and final rocker schutz.

It is wonder what tarps can do to corral sand when you are blasting outside a cabinet.

I use a 12 x 18 tarp and fence posts to make a container to put my work in along with the 5 gallon sand bucket and blast gun. Hose is draped in and attached to one of the fence posts. When I run low on sand, I use a street broom to sweep it up. Then I screen it back into the bucket. Only added equipment is a full face mask and breathing mask.

I have a soda blaster. I blast in in back yard. The trouble with soda is that the resulting dust cloud drifts a long way. I have to watch the wind direction and be sure the wind isn't going to blow the soda dust towards the neighbors behind us. When I do soda blast, my truck 150 feet away will get coated with soda dust. The garage next to where I blast of course is coated and I have to pressure wash it afterwards. Soda is much messier (dustier) than sand.
