It is also not suitable for removing dried resists based on acrylics and to remove dried acrylic paints, which can be removed with an alkaline solution.
The detergent does not evaporate and remains active as long as it is on the plate. Therefore, when used correctly, but one quarter to one tenth of the amount is required compared to volatile detergents such as turpentine or benzene. In practice it is sufficient to add a few drops (small plates) or a dash (larger plates) detergent to the plate and distribute it. Then give it time to be absorbed and do its work. After removal of ink, etching grounds, etc. clean plates and tools with soap and water, dry thoroughly and immediately.
