Cleaning Aluminum Moulds

[ncbearman]

Hello all,

What is the best way to clean aluminum moulds without scarring. I purchased several that have been "laying around". Some have had mud daubers make homes in them. Thanks in advance for your help.

Hot water, dish soap, tooth brush.

I use Mean Green on aluminum molds , strong stuff & has never etched the surfaces.
