Paint condensate residues were the problem with the basic cleaning of a painting machine of a company in the Stuttgart area: The painting machine had to be cleaned every year and the previous cleaning did not lead to any success in the given time, as the paint condensate residues are very greasy and sticky, comparable to tree resin. For this reason, our colleague was asked for help. On site, he used our neutral industrial cleaner  Indumaster Step IR 16. After a very short reaction time, the paint condensation residue was removed. The customer was more than satisfied with this, as the residues could be removed very well with the help of IR 16 and even further below the specified time.
