What is ultrasonic cleaning?
Ultrasonic cleaning is a highly effective precision cleaning method that uses high-frequency sound waves to create millions of microscopic cavitation bubbles in a liquid cleaning solution. These bubbles rapidly form and collapse, producing intense localized energy and micro-jets that lift and dislodge contaminants from surfaces - including grease, oil, dirt, and other residues. When paired with Simple Green products, this method delivers powerful cleaning performance without the need for corrosive chemicals.
Can Simple Green be used in ultrasonic cleaning machines?
Yes, all water-based Simple Green products are compatible with ultrasonic cleaning machines. However, they should not be used in machines running solvent-based solutions. Simple Green products work by reducing surface tension to penetrate, lift, encapsulate, and break down organic residues, preventing redepositing onto cleaned parts.
Which Simple Green products are best for ultrasonic cleaning of engine and transmission components?
Extreme Simple Green Aircraft and Precision Cleaner: Preferred in the aviation industry for multi-tank and bench ultrasonic machines. It effectively removes tough organic contaminants without harming sensitive surfaces.
Crystal Simple Green Industrial Cleaner & Degreaser: Pharmaceutical-compliant formula suitable for precision cleaning in medical device and pharmaceutical manufacturing. It leaves no residue and is safe for materials not prone to corrosion.
How long can the cleaning solution be reused?
Simple Green products can be reused until they lose their cleaning effectiveness, typically after several cleaning cycles. While a dirty solution may still clean effectively, many users prefer to replace the solution for optimal cleanliness.
What temperature range is recommended for ultrasonic cleaning with Simple Green?
Simple Green products perform best at temperatures up to 42°C (108°F). They can tolerate higher temperatures, up to 60°C (140°F), but only for very short periods of time. Prolonged exposure to heat will reduce cleaning efficiency.
What is the recommended rinse process after ultrasonic cleaning?
After cleaning, parts should be rinsed using deionized, softened, or fresh water, depending on industry requirements, to remove any remaining cleaning solution and residues.
