Technicians Guideline

At Global Chemical Solution (GCS), precision, safety, and consistency define our success. Our technicians have developed and refined a specialized procedure for the GCS Black Banknote Cleaning Process, based on years of scientific research and field-tested expertise. This process is delicate and requires strict adherence to ensure effective results and protect the integrity of the currency.

It is not just advised—it is absolutely essential that every individual involved in the cleaning process follows these instructions meticulously. Failure to do so may result in:

• Irreversible damage to the banknotes
• Compromised chemical performance
• Wasted materials and financial loss
• A negative impact on our professional reputation

⚠️ Why Following Instructions Is Non-Negotiable

The cleaning of stained or blackened banknotes using SSD solutions, activation powders, and neutralizing agents involves a controlled chemical reaction. These substances must be applied with exact precision, in the correct sequence, and under safe conditions.

Even minor deviations in:

• Temperature
• Exposure time
• Dosage
• Rinsing techniques

can drastically affect the outcome and may render the currency unusable.
