Acetone or brake cleaner 17. Scale that can measure lbs, oz. Materials Needed: 1. Distilled water 2. 99% Sodium Hydroxide - 5lbs per 1 Gallon of distilled water 3. 99% Potassium Nitrate - 2.5lbs per gallon of distilled water 4. WD-40 Process: First add the distilled water then add the sodium hydroxide and stir the sodium until the exothermic reaction is complete and the solution clears. Always wear a respirator during the process. No aluminum can ever go into the solution. Then add the potassium nitrate while stirring the whole time. After the Potassium has been thoroughly mixed you can start the burner. Use the Thermometer to bring the temperature to 250 degrees Fahrenheit slowly. Some of the solution will burn off and evaporate during the process so you will have to add more distilled water. Poor the water down the side of the pot slowly to avoid and splashing or bursts. Once it starts to boil you are ready to add in the part. Make sure the Part is suspended in the solution with steel wire that has been degreased. Small parts do not need to be suspended so you will need a stainless steel frying basket to put into the solution. All the parts to be blued must be stripped and degreased before hand so you do not hot blue for a long durations. The faster you can do it the better. Means less blueing to evaporate and less time wearing the goggles and respirator. Do not touch the parts with bare hands after it has been degreased. Suspend the part in the solution for 5 - 8 mins. After take out and quench in hot water. After is has cooled down take it out and place it into wd-40 for 24 hours. Then the part comes out and you wipe all left over residue and oil off.

Please call you bailer facility to see where you can dispose of your solution. The Ph level is high and it must be disposed of properly and legally.
