1. Description of the PURAQLEEN

procedure (Cleaning with demineralized

water)

The high chemical-free cleaning power of pure water is the principle the Lehmann 

PURAQLEEN procedure for glass and façade cleaning is based on. Tap water is conduc-

ted through a mix-bed resin system there (granulate bottle). The minerals contained in 

tap water adhere to the granulate (mix-bed resin). The tap water is demineralized and 

fed to the pump as pure water and to the cleaning head afterwards. Pure water has 

not only excellent wetting capacities, but also dries without leaving stains and streaks 

even in strongest sunlight. Thus, a use of detergents can be omitted in many cases 

(exception: greasy, oily or very heavy pollutions).

1.2 Safety remark

Pure  water  (=  demineralized  water)  freezes  –  different  from  tap  water  –  already 

at +1°C. Thus, no cleaning works with demineralized water are allowed at outside 

air temperatures below +3 °C. The demineralization station and the mix-bed resin 

must be protected against temperatures below +1 °C and frost, because frost may 

damage the water-conducting parts of the cleaning system. Mix-bed resin must be 

stored frost-free and must be used only for cleaning works up to +50 °C maximum.
