Your components are not all the same, and neither is the contamination you are dealing with. From light dust on a PCB to heavy grease packed into a connector, the right precision cleaning solution makes the difference between a clean repair and a failed one. Choose the strength that matches your application.
Medium Duty Electro Klene™
Our Medium Duty ElectroKlene™ is a moderate-strength cleaner that removes dirt, dust, light grease and oil from complex electronic assemblies during manufacturing, bench repair, and field service.
Heavy Duty Electro Klene™
For heavier residue, Heavy Duty Electro Klene™ removes heavy oil, grease, dust, dirt, and more from electrical and mechanical assemblies that are resistant to other solvents.
Multi-Purpose Flux Remover
Stoner’s Multi-Purpose Flux Remover rapidly removes rosin-based solder flux from solvent-resistant components with a high-pressure stream, giving repairs a factory-new appearance.
Multi-Purpose Freeze Spray
Stoner’s Multi-Purpose Freeze Spray quickly lowers component temperatures to -65°F to speed up repairs and save time when tracing circuit faults. Solidifies or freezes viscous and fluid materials.
GUST Spray Anyway 360° Duster
With the GUST Spray Anyway 360° Duster, liquid will never be expelled, regardless of the angle used when spraying. It works flawlessly every time, at any angle.
Rubber Parts Cleaner
Our Rubber Parts Cleaner removes gummy residue and correction fluids from belts, feed rollers, and all kinds of rubber components fast. And it won’t dry out rubber like other brands.
Isopropyl Alcohol
Critical Cleaning’s Isopropyl Alcohol is a solvent that’s fast-evaporating and leaves no residue. It’s 99.9% pure—without the 25% water content of some isopropyl alcohols.

Shop Precision CleanersFAQs About Precision Cleaners
Not sure which product is right for your application? Here are answers to the questions we hear most from maintenance technicians, engineers, and MRO teams.
Contact cleaners are formulated to remove oil, grease, dust, and dirt from connectors, relays, and electronic assemblies. A flux remover is specifically designed to strip rosin-based solder flux from PCBs and SMT components after soldering. Both leave no residue, but each targets a different type of contaminant.
Most products in the line are formulated as a non-flammable solvent, including Medium Duty Electro Klene, Heavy Duty Electro Klene, Multi-Purpose Flux Remover, and Multi-Purpose Freeze Spray. Always check the individual product label for full safety details before use.
The Plastic Surface Cleaner is the recommended plastic-safe precision cleaner for computer casings, printer housings, copiers, and similar hard surfaces. For assemblies with mixed materials, Medium Duty Electro Klene is also generally safe for most nearby plastics and coatings.
