- Neutralizing solution (such as baking soda and water)
Safety Precautions
Before proceeding, its vital to prioritize safety. Always wear protective gloves and eyewear when handling acids to prevent any accidental exposure. Furthermore, ensure that you are working in a well-ventilated area to avoid inhaling any harmful fumes.
Step-by-Step Guide to Acid Washing
With the necessary materials at hand, you can proceed with the acid washing process. Heres a step-by-step guide to help you through:
Step 1: Prepare Your Knife
Begin by thoroughly cleaning your folding knife to remove any dirt or oil. Use sandpaper or a scouring pad to lightly scuff the blades surface, allowing the acid to adhere better.
Step 2: Mask Off Areas
Use masking tape to cover any parts of the knife that you dont want to be affected by the acid, such as the handle or pivot area.
