Due to an incompetent tradesman, our construction site was left with windows contaminated by primer. This primer acted like glue and could only be contained manually, never truly removed. Afraid of scratching everything, we looked for cleaning products and came across Hatoch. We ordered a stick from their website but unfortunately found it ineffective.
Most people would probably give up at this point, get annoyed, and write a negative review. However, since we were desperate and desperate to clean the area, I decided to contact the manufacturer and was surprised to reach a competent employee right away. He was also surprised that the stick wasn't working, and together we figured out that this was due to a particular deep-penetrating surface.
What happened next was very positive: The managing director bought more of the primer I had used and adjusted the mixture accordingly. I received this adjusted mixture to test a few days later, and lo and behold – almost everything came off.
I was amazed by the customer service and very pleased with the effect of the (adapted) product, so I can highly recommend Hatoch and the sticks.
