Packaged in PET bottles with a volume margin of 900 ml.
Milk bottles with a wide mouth are used for easy filling. the packaging is convenient and safe to use, securely closed with a screw cap.
The volume reserve allows you to pour water directly into the bottle and get the required volume concentration once. After etching the boards, we again pour the solution into the same bottle for storage and reuse.
Total, we get as in the famous advertisement: ".... just add water!".
Etching boards.
For etching, use glass or plastic containers such as a photographic cuvette. Place the board in the solution with the pattern facing up, the entire surface of the board should be filled with the solution.
The etching process is accelerated if the vessel is rocked or heated. Pickling produces toxic fumes, so work either in a well-ventilated area or outdoors. Periodically check the condition of the board by lifting it up for inspection with wooden or plastic sticks; metal tools and devices cannot be used for this purpose.
After making sure that the foil in unprotected areas has disappeared completely, stop the etching process.
Transfer, for example, with a clothespin, the board under running water and rinse thoroughly, then dry it at room temperature.
If you intend to use the solution, re-drain it into a tightly sealed container and store in a cool, dark place.
Please note that with repeated use, the effectiveness of the solution decreases.
