Corrosives cleaning?

Dear Friends,

Regarding the danger of ammonia in bore-cleaners, I put a couple of steel welding rods of .0625" diameter in a bottle of Hoppe's Bench Rest Copper Solvent and in a bottle of Sweet's 7.62 Solvent (5% ammonia) on 8/2/01. Etching was soon visible on the Hoppe's rod and as of this date the rod has lost about .0003" of diameter. The Sweet's rod shows absolutely no etching or loss of diameter.

Has anyone else made any actual tests?

Regards,

Jack Owens
