Washing & Cleaning

The special consistency of GRANDER water significantly reduces the susceptibility to germs and thus significantly reduces the need for detergents, cleaning agents and detergents with the same result.

reduces cleaning effort

The use of GRANDER water revitalization reduces lime deposits, rust formation, silting and sedimentation and thus massively reduces your cleaning effort.

At the same time, revitalized water naturally reduces the unpleasant odors associated with the use of detergents, cleaning agents and cleaning products.

minimizes residues

By reducing the use of detergents and cleaning agents and making them more effective, GRANDER water revitalization reduces harmful residues in textiles and on surfaces.

The use of revitalized water according to Johann Grander thus ensures a more pleasant room and living climate overall.

  • Many years of experience with GRANDER without water softening system

    Greetings Josef!  I found out more about GRANDER® based on a recommendation I received.  Since our water softening system was due to be replaced, we decided to install GRANDER® 13 years ago and not to utilize the water softening system any more.
