[RASMB] Aluminum centerpiece cleaning recommendation?

[Cole, Richard A]

If you see aluminum oxide then the aluminum is corroded and weak. You will never get a good seal especially at the speeds you will be running at

Dear Niko- CsCl is readily soluble in water, so I suspect that what you are looking at is aluminum oxide, which is not soluble in any solvent. I am not sure that there is a way to remove it that does not involve abrasion. Best wishes, Tom From:

Dear all,



I want to use Aluminum centerpieces, but they appear to be crusted with CsCl. Could you please advise on a proper cleaning reagent to remove the crust? I have so far tried ultrasonications for 30 minutes in baths of water, EtOH, and 2% Hellmanex...



Your input would be gratefully appreciated!



Best,



Niko
