Walnut Shells for delicate blastingThese shells were excellent for my project. I was able to vacuum them up three times and screen them and remove the debris before reusing them before they were completely spent. They allowed me to blast materials without generating any additional heat or damage to the surface of item being blasted. Removal of paint and rust did take some patience but, remember working on delicate items it takes time and a lot of volume of air.

Removes Caked On Dirt and Grease.I had never used walnut shells as a blast medium before, but I decided to give it a try with a pickup truck restoration project that I'm working on.
I anticipated using it for paint removal, which I have not tried yet; but what it really worked great for was dirt and grease removal.
The walnut shells wouldn't work with my siphon outfit, so I had to drain the sand from my pressure blaster and load the walnut shells. That proved much better, but the shells, due to their size, kept clogging the 1/8 inch nozzle. It probably would work perfectly with a 3/16 nozzle, but I didn't have one handy.
At any rate, the shells did a great job of blasting 40 years of hardened grease and caked on dirt from the transmission, and left it looking like new, and I didn't have to worry about any grit getting into the transmission and harming it.
It took nearly an entire 50 pound bag to clean the transmission, but it certainly beat the alternative (scraping and wire brushing.)
I plan to purchase more walnut shells from Eastwood when it's time to clean the undercarriage and suspension of my project.

excellent buyThis media is great for cast iron,heavy aluminum and sheet metal.It doesn't create much dust so visibility is good if your blasting in a booth.And if you keep your pressure below 90psi you can reuse it multiple times.

Trying to use Eastwood's gun & pedal kit with #12 walnut shells. The air is dry. Pressure and volume are correct. Still, the media will not pass through the gun. It packs into the air passage inside the gun's handle. Is something more needed?

This media is way too coarse to run in the foot pedal, any of our cabinets or free standing blasters we sell.

Would walnut shell media be good for removing layers of paint off of cabinet doors and drawers? If so what pressure would I set my blaster on for walnut shells?
Asked by: Buster 24
12-20 grit Walnut shell is recommended for removing paint and carbon from ferrous metals.. It will work on wood but you test in an inconspicuous location first. Use at 80psi max.

Looking to remove the second/peeling layer of paint on a '65 TBird. Would Walnut shells be the safest media to use to remove the second layer of paint while protecting the original paint? Or would a chemical stripper be a better choice?

Besides the 'SpeedBlaster' that was recommended in another question, are any of your other Blasters able to handle this size media? A few projects I'll be handling are needing this non-marring/non-impact damaging type media, and I don't want to reload oft
Asked by: GHOSTRIDER
This is the only blaster we currently sell that can use the walnut shell.

Would walnut media be a good choice for cleaning smoke damaged wood joists and studs?
Asked by: bbazata
Walnut shells would be a good media for blasting your smoke damage, however, you will need a blaster that can handle that size media.

Does walnut work in cabinets (reuse) or does it break down with one use
Asked by: Randy
Our cabinets are designed to be used with media that is 60 grit or finer so 60 or a larger number. This walnut shell is a 12-20 grit mixture and is way too coarse to use in any of these units.
