Cleaning Chemicals for Electrical & Electronics Manufacturing
Electronics cleaning is judged by what is left behind rather than what came off. Flux residue, ionic contamination and cleaner films all cause failures that appear weeks later as leakage or migration. Power Clean supplies neutral-pH aqueous chemistry for copper, brass and aluminium assemblies, plus non-chlorinated solvent options for equipment that cannot see water.
The short answer
Electrical and electronics cleaning needs low-residue, neutral-pH chemistry: alkaline cleaners tarnish copper and leach zinc from brass, and any ionic residue left between fine-pitch conductors attracts moisture and causes surface leakage. Non-chlorinated safety solvents cover equipment that cannot be wetted.

The Electrical & Electronics Failure Modes
These are the problems we are called in for most often in this sector — and what causes each one.
Copper tarnishes, brass dezincifies
Alkaline chemistry discolours copper and selectively leaches zinc out of brass, turning it pink. Neutral-pH cleaning keeps both at their original colour and composition.
Ionic residue causes latent failure
Flux activators and cleaner salts left between conductors are hygroscopic. They draw moisture, create a leakage path, and can drive electrochemical migration long after the board passed test.
Equipment that cannot be wetted
Motors, switchgear and assembled control gear cannot go in a tank. A high-flash, non-chlorinated safety solvent cleans by dissolution and flashes off dry.
Material compatibility
Component markings, plastics, elastomers and conformal coatings all have chemical limits. A cleaner that is excellent on metal can destroy legends and seals.

Electrical & Electronics Cleaning — FAQ
What cleaner is safe for brass and copper parts?
A neutral-pH cleaner in the 7–9 range. Alkaline chemistry tarnishes copper and selectively leaches zinc from brass, leaving a pink, weakened surface. Power Clean NF-14 is formulated for non-ferrous work.
Do no-clean fluxes really need cleaning?
Often yes. The no-clean assumption breaks down under conformal coating, in high-humidity environments, in high-voltage designs, and wherever the assembly must pass an ionic-contamination test. In those cases the residue must be removed.
How do you clean equipment that cannot be immersed?
With a high-flash, non-chlorinated safety solvent. It dissolves the soil and evaporates without residue, so it works on motors, switchgear and assembled machinery where there is no tank, heat or rinse stage available.
