How To Use Safety Pickle & The Importance Of Using Plastic Tweezers

SAFETY PICKLE DIRECTIONS FOR USE

Step 1

Heat 1 litre of tap water to approximately 50°C (122°F) in a container capable of resisting acids and caustic solutions (a chemical or polypropylene container is recommended, although glass, most glazed china and most plastics are fine). Many Kernowcraft customers use a slow cooker as their pickle bath which is great as it keeps the pickle warm and is protected with a lid. If you're going to do this, ensure there is no metal inside of the cooker which could contaminate the pickle.

Step 2

Add approximately 50g of the granules to the water (always add pickle to water, not water to pickle) and stir with a wooden spoon or spatula.

To mix a smaller amount, use 250ml of water (approximately 1 cup) and add 12.5g of crystals (approximately 2 level teaspoons).

Step 3

Immerse components to be deoxidised in the solution, which should be maintained at 50°C if possible (the heat speeds up the process but is not entirely necessary) and removed once all the oxides and flux residue is gone, your pieces would also be  fine to leave overnight. Once it's ready to take out, rinse with water.

You can use your safety pickle repeatedly over a number of weeks, depending how often you use it. The solution will start to go blue when it is exhausted and needs renewing. Instead of having to heat your pickle up for use every time you want to use it we have found it works fine when dropping hot pieces into the cold solution.

Always Wear Safety Goggles

Goggles or safety glasses should be worn and any splashes washed off immediately.

Fire fighting measures: Not considered flammable. Extinguishing media dependant on other constituents of fire. May give off sulphur dioxide fumes so wear breathing apparatus.

Spillage/disposal: No specific precautions required. Sweep up powder and collect in a suitable container.

Handling/storage: No specific precautions required but when handling, wear a protective mask, gloves, goggles and non-absorbent clothing.
