Instructions for making dewatering water

1. Solution Preparation : Dissolve 100 grams in 1 liter of warm water. This provides a suitable concentration for treating discolorations.
2. Application : Apply the oxalic acid solution to the discolored area and allow it to absorb. This can be repeated until the discoloration disappears.
3. Treatment of the Entire Surface : After removing the discoloration, treat the entire surface with the solution, not just the previously treated area. This helps in evenly restoring the appearance of the surface.
4. Rinsing : Rinse the treated surface thoroughly with clean water. This is essential to remove residues of oxalic acid and to neutralize the acid.
5. Safety measures : The use of personal protective equipment, such as gloves and goggles, is strongly recommended to prevent skin and eye irritation.
6. Other Considerations : Inform users that it is important to work in a well-ventilated area and to avoid direct contact with the skin and eyes.
