There have been a few users questioning the safety of HumminGuru cleaner, and we are happy to clarify and relieve the safety concerns that you may have.
The product, HumminGuru ultrasonic vinyl record cleaner, is designed in a manner to protect your vinyl records and the cleaning machine from damages due to possible overheating during operation. In general, it is recommended to start with warm water between 25˚C/77˚F to 35˚C/95˚F in the ultrasonic bath to result in optimal cleaning effectiveness. The ultrasonic activity may gradually increase the water temperature. In the interest of safety, there incorporated the thermal sensors in the HumminGuru machine to monitor the cleaning water temperature. When the water temperature reaches 55˚C / 131˚F or above, the machine will automatically stop and alert with a solid blue light.
If it happens, please drain and change the water to mitigate the heat, or simply let the water cool down. Allow the machine to cool down for 10-15 minutes before resuming the cleaning operation.
