A good alkaline cleaning solution is prepared with 5-6 oz. SD ANODISE & CHROME STRIPPER added to one gallon, or 4.5 litres of water. This solution may be used at room temperature but the stripping time is slower. Heating the alkaline solution to a Temperature of 160ï F, considerably increases the rate of chrome removal. The brush plating technique is ideal for use with this solution, especially for decorative chrome plate removal. A typical set-up for stripping Chrome plate electrolyticly using SD ANODISE & CHROME STRIPPER solution is shown here.
The recommended procedure is as follows:
- Connect the piece to be stripped to anode (positive) connection of your power unit, and immerse work in Anodise & Chrome Stripper Solution
- Connect the GP Plates to the negative terminal of your power supply.
- Adjust current until a current density of 1/2 to 1 amp. Per. sq. in. is obtained. Maintain this current density for approximately five minutes.
- Remove work and inspect to see if all chrome has been removed. If not, repeat cycle as outlined previously.
- Water rinse work and clean work according to recommended CLEANING INSTRUCTIONS PRIOR TO PLATING (SEE MANUAL). The part is then ready for plating.
Note: The above procedure is recommended for the removal of heavy Chrome deposits (.00211 or over), which have been deposited over nickel.
CAUTION: EXCESSIVE STRIPPING ON THE BASE METAL AFTER CHROME HAS BEEN REMOVED IS NOT RECOMMENDED. THIS APPLIES PARTICULARLY TO HIGH CARBON STEELS. A PERIODIC FIVE MINUTE INSPECTION OF THE WORK SURFACE IS HIGHLY RECOMMENDED. (It is usually
better to leave the nickel plate intact, and plate over it with copper.)
