3. Setup
Before using the Gesswein Classic Ultrasonic Solution, ensure you have an appropriate ultrasonic cleaning machine and a clean, well-ventilated workspace.
- Prepare the Ultrasonic Cleaner: Ensure your ultrasonic cleaner is clean and free from previous cleaning solutions or debris.
- Ventilation: Work in a well-ventilated area to avoid inhaling any fumes, although the solution is designed to be environmentally safe.
- Safety Gear: Wear appropriate personal protective equipment (PPE) such as gloves and eye protection, especially when handling concentrates.
4. Operating Instructions
Follow these steps for optimal cleaning results:
- Mixing Ratio: The recommended mixing ratio is 35 parts water to 1 part solution (35:1). For example, to make 36 gallons of ready-to-use solution, you would use 1 gallon of Gesswein Classic Ultrasonic Solution and 35 gallons of water.
- Prepare the Solution: Carefully pour the required amount of water into the ultrasonic cleaner's tank. Then, add the appropriate amount of Gesswein Classic Ultrasonic Solution concentrate according to the 35:1 ratio.
- Stir (Optional): Gently stir the mixture to ensure even distribution of the concentrate, though ultrasonic action will also help mix it.
- Load Items: Place the items to be cleaned into the ultrasonic cleaner's basket. Ensure items are fully submerged in the solution but do not overload the basket.
- Set Cleaning Cycle: Refer to your ultrasonic cleaner's manual for recommended cleaning times. Start the ultrasonic cleaning cycle.
- Rinse Items: After the cleaning cycle is complete, carefully remove the items from the basket. Rinse them thoroughly with clean water to remove any residual solution and loosened debris.
- Dry Items: Dry the cleaned items using a soft, lint-free cloth or allow them to air dry.
5. Maintenance
Proper maintenance ensures the longevity of your cleaning solution and effective cleaning results.
- Solution Replacement: Replace the cleaning solution regularly, especially when it appears cloudy, discolored, or its cleaning effectiveness diminishes. The frequency depends on usage and the level of contamination.
- Tank Cleaning: Periodically clean the ultrasonic cleaner's tank according to the manufacturer's instructions to prevent buildup.
- Storage: Store the Gesswein Classic Ultrasonic Solution in its original container, tightly sealed, in a cool, dry place away from direct sunlight and extreme temperatures. Keep out of reach of children and pets.
