Product Description




Parts must be free of grease, alkalinity or acid when  Blue Black C-44 is applied. Parts must be thoroughly cleaned and deoxidized prior to blackening. Cleaner 104 is recommended for removing heavy oils and oxidation. Do not use petroleum-degreasing solvents that leave a residue on the surface. Rinse thoroughly with overflowing cold water to remove residual cleaners and dust. It is important that alkaline cleaners are completely rinsed off prior to blackening. 


IMPORTANT: Triple- S does NOT recommend using any sort of alcohol, solvent, acid or degreaser to clean parts prior to solution application. Cleaner 104 is a great cleaner to ready parts for Blue Black C-44 or even powdered cleaners such as Ajax or Comet can also be used. When bluing copper, be sure to use the cleaner in conjunction with a scotch-brite pad and apply medium-strength scrubbing to prepare the part then thoroughly rinse with fresh water. Cleaner 104 run off should be contained and disposed of as per local hazmat disposal laws.
