Description
Ottosonic is a non-ammoniated ultrasonic cleaning concentrate formulated in California, USA. Environmentally safer and biodegradable when diluted, it delivers professional cleaning power for jewelry, instruments, and small machine parts. Formulated for jewelers who need performance without harsh ammonia fumes, Ottosonic leaves a bright, shiny finish with no rinsing required—just air-dry.
Highly economical at a 40:1 water-to-concentrate ratio, Ottosonic stretches further than most concentrates on the market. Increase the concentration for heavier residues such as polishing compound or investment buildup. From a 2 oz trial size to a 5-gallon shop supply, it scales to fit any bench operation.
