chewing gum can be removed from all floor surfaces just with pure water with our high pressure cleaners. the specially developed chewing gum nozzle takes approx. 2 seconds to remove each chewing gum spot completely. the disadvantage is that, where there were black chewing gum spots there are now white spots on your floor area. for this reason , the professional falch units provide a complete solution for complete floor cleaning. the units are so powerful that two-gun operation can be employed without any problems. whist one person removes the chewing gum, the other person cleans the complete floor area afterwards. this is also possible indoors as a result of our patented water extraction.
