Cleaning is an essential process within electronics manufacture and has been used for many years to remove potentially harmful contaminants during PCB manufacture.

Such contaminants include flux, solder and adhesive residues, and other more general contaminants such as dust and debris present from other manufacturing processes.

The purpose of cleaning, specifically within the rapidly expanding electronics industry, is to essentially improve product lifetime by ensuring good surface resistance and by preventing current leakage leading to PCB failure. This developing market sees modern and future electronics becoming smaller and smaller and the requirement for high performance and reliability is stronger than ever. In order to achieve good insulation resistance and ensure adequate adhesion of conformal coatings and encapsulation resins, the cleanliness of the electronic assemblies is essential.

There are many stages where cleaning is required; prior to stencilling and soldering in order to remove contaminants from the many previous production stages, after stencilling to remove excess solder paste/adhesive and after soldering to remove corrosive flux residues and any solder balls.

In industry today, many manufacturers are turning to ‘no clean’ processes, implying that cleaning is not required after soldering. In the ‘no clean’ process the solids content of the flux is lower than traditional types, however they still contain rosin and activator. Such residues, along with any other unwanted elements collected due to the missing cleaning stage, could cause issues with adhesion and possibly affect the performance of the protecting media applied, ie. Encapsulation Resins or Conformal Coating. It can therefore be stated that even with advances in new technologies, such as ‘no clean’ fluxes, cleaning is still an essential multi-stage process within the electronics industry.

Finally, there are also cleaning stages required for the removal of coatings and adhesives when re-work is necessary, for the cleaning of individual components and for maintenance of the production line.

Safewash Super

5 Litre - 25 Litre - 200 Litre

Product code: SWAS05L - SWAS25L - SWAS200L


The Safewash range consists of water based cleaning solvents, suitable for the cleaning of PCBs and production equipment. The Safewash products are water-based, non-flammable, 100% ozone friendly, biodegradable solvent blends designed to clean to well within the world's military cleanliness standards.(ANSI-J-001B/IPC TM-650).

SWAS removes all types of flux residues (RA, RMA, no-clean and water-soluble) quickly and efficiently, with minimal environmental effect using low cost, readily available cleaning equipment. It is ideally suited for the removal of very stubborn flux resides and no-clean fluxes, which can be extremely difficult to remove. SWAS will remove them to military cleanliness standards. It also has a lower odour than the other Safewash variants and is easy to rinse. For spray applications where foam generation may be a problem, an alternative Safewash should be used:


Key Properties:
  • SWAS is similar to SWAJ but with enhanced cleaning performance. Cleans flux residues and no-clean flux to military cleanliness standards.
  • Low odour, non-hazardous and for use in batch cleaning systems using ultrasons or spray-under-immersion,
