Comprehensive FAQ Section

Q1: What is the best solvent for ultrasonic cleaner use with jewelry?
A1: For jewelry, the Calyptus Ultrasonic Jewelry Cleaning Solution Concentrate (Product 9) is highly recommended. It’s plant-based, non-toxic, and specifically designed to safely clean delicate items like jewelry and eyeglasses without harsh chemicals.

Q2: Can I use regular dish soap as the best solvent for ultrasonic cleaner?
A2: While some people use dish soap for light cleaning, it’s generally not recommended as the primary best solvent for ultrasonic cleaner. Dish soap can create excessive foam, reduce the effectiveness of cavitation, and may not adequately break down specific types of grime like carbon or rust. Specialized ultrasonic cleaning solutions are formulated to optimize cavitation and provide superior cleaning without damaging your machine or items.

Q3: How much concentrate should I use when mixing an ultrasonic cleaner solution?
A3: Always follow the manufacturer’s specific dilution instructions. For example, some solutions like the unnamed 32oz Gun Cleaner (Product 8) use a 1:250 ratio, while others like Durabasics (Product 6) might be 1:5. Using the correct ratio ensures optimal cleaning performance and prolongs the life of your solution.

Q4: Are ultrasonic cleaning solvents safe for all metals and plastics?
A4: Most specialized ultrasonic cleaning solvents are designed to be safe for a wide range of common metals like aluminum, brass, and steel. However, some solvents are not suitable for certain coatings (e.g., Cerakote) or very delicate materials. Always check the product description for compatibility. Solutions like CREWORKS (Product 10) are specifically formulated to be safe for plastics and delicate electronics, making them more versatile for mixed-material assemblies.

Q5: How often should I change the cleaning solution in my ultrasonic cleaner?
A5: You should change your cleaning solution when it becomes visibly dirty, cloudy, or if its cleaning effectiveness noticeably decreases. The frequency depends on how often you use your cleaner and how heavily soiled the items are. Using a fresh solution ensures the best cleaning results.

Q6: Can I heat the ultrasonic cleaning solution for better results?
A6: Yes, many ultrasonic cleaners have a heating function, and using warm or hot water (within the solution’s recommended temperature range) can significantly improve cleaning efficiency, especially for removing oils, greases, and heavy grime. Some solvents, like Lucas Oil (Product 3), are even formulated to be safer and more effective in heated units.

Q7: What is the best solvent for ultrasonic cleaner when dealing with heavy carbon buildup on engine parts?
