Soda Blasting Electrical Parts-Fuse Block, etc.

Just wanted to share the results of a quick little experiment I tried last night.

My dash harness is in overall good shape, just very dirty with some corrosion, especially in the fuse block and plug ends, bulkhead too.

I have all new harnesses for the engine-forward but wanted to clean up everything else from the firewall-back to re-use if possible.

For the purpose of this quick test, i just used my small hand-held mini sand blaster and restricted the siphon pickup tube by slipping a plastic cap over it and drilling one very tiny hole in it (less than 1/16 inch).

I just grabbed a box of Baking Soda from the kitchen for the test.
Anyways, it worked really good! Didn't damage the plastic at all either. I just did one half of the backside of the fuse block for before & after comparison.
Thinking I might go buy a small blasting cabinet and set it up for this to contain the mess. Would be great for cleaning up all my door latches and lots of other small stuff as well.
I'm sure this is probably not new to many here but I tried searching for it with no good results so decided to make a thread about it.
If anyone has any tips or input that would be great. Hoping the idea of buying the small blasting cabinet to use with soda is a good one!
