PreciClean P91

Amsonic PreciClean P91 is a liquid, highly alkaline and highly effective concentrate for the automatic cleaning of stubborn contaminations on soldering machines, apparatus, mechanical components etc. Amsonic PreciClean P91 doesn't corrode iron and steel, but check non-ferrous metals and aluminium alloys on their resistance.

Amsonic PreciClean P91 automatically removes stubborn contaminations such as burnt-on greases, oils, waxes, organic or inorganic traces as well as silicones.



Amsonic PreciClean P91 considerably reduces the surface tension of the cleaning solution and because of its good wetting performance, removes contamination easily. The excellent emulsifying and dispersing capabilities prevent removed particles from being redeposited. Special tensio-active surfactants guarantee an absolute rinsing after cleaning.

Amsonic PreciClean P91 is based on a phosphate-free formula. Instead of corrosive substances such as free chlorine, mild cleaning enhancers have been used to make the product safe for materials.

The most favourable dosage mainly depends on the hardness of the water and the contamination's stubbornness. For very strong deposits it can be applied at a higher concentration. A thorough rinsing after cleaning is necessary.

The recommended concentration for use is:
Dosage: 2-5%
Temperature: 60-80 °C
Exposure time: 3-10 min.
