In Berlin, our colleague was called out due to problems with the floor cleaning of the Adapt Apartments training room. The floors were not getting properly clean with conventional cleaning. Therefore, a test cleaning with our alkaline intensive cleaner Erol G 490 and our acidic intensive cleaner Erolcid G 491 was carried out. The results are clearly visible on the small test area and both products are now used for special cleaning. In addition, there has been a changeover to Planta products for maintenance cleaning.
