BIO RAD PTC-200 Operation Manual page 34

If mild cleaning agents do not remove radioactivity, harsher cleaners may be used.
Users have suggested the detergent PCC-54 (Pierce Chemical Co., Rockford, Illinois;
Pierce Eurochemie B.V., Holland), Micro Cleaning Solution (Cole-Parmer, Niles, Illinois),
and Dow Bathroom Cleaner (available in supermarkets).
Caution: Harsh cleaning agents are corrosive to aluminum and must
never be used on bare aluminum blocks. Bio-Rad Alpha unit
blocks are anodized, so they have a protective coating of
aluminum oxide. Still, harsh agents (such as those above)
must be thoroughly rinsed away within a few minutes of
application, or the anodization will degrade.
