Any tips for removing investment residues post-casting?

I have just cast a large torus form which is hollow and has only small openings. The whole piece is full of investment, of course. I've tried using the ultrasonic but that hasn't done much. Normally the ultrasonic, a heated pickle and the sandblaster are what I use, but the sandlbaster won't get into the small openings on the piece and the other two methods have been fruitless.

What about tumbling in water only? Or hot water and a toothpick? Sounds like a hellish job.

 

That sounds like the one I was thinking of! It might just be that.

Power hose??? Maybe hold underwater and use your air compressor to blast it out?? When you figure it out let us know:))-ann

Actually, that sounds like a good idea. I wonder where I could get a pressure-washer.

I had a sculpture professor who had students take castings to the car wash to blast off investment...maybe this could work if the piece isn't too small overall.

I think it is too small for that! Thanks for the suggestion.

Worst-case scenario you could use an investment remover in an ultrasonic and a syringe. And last resort, each time you bring the investment to temp it loses more and more of its strength.

I am very curious as to what winds up working for you.-Sean

We use a water jet blaster. and if we can't we use warm water soak overnight, then poke it a bit to make sure the silt comes out.

 

Excellent. I will try the soaking as my piece is too small to take to the car wash!

Our jet wash is especially for plaster! It works just like a grit blaster, but with water. If you have no luck with the soaking and you're this way let us know. If not maybe a local casters will let you have a go on theirs!

 

You could try Gypsof, I have used it my self and it really works.  Mix up a solution and let your piece soak in it.  Pehaps you could combine it with the use of the ultrasonic?  Zero D is very friendly, and could answer any questions you may have about its use.

Fantastic, thanks. I will need to find a UK supplier of this.
