Many people have the same question. The protective film on the stainless steel door is difficult to remove after using fot a long time. Does it work to heat the film with electric hair drier? Is there any other ways? The answer is yes. There are many other ways:
1. If the film is not too big, you can apply some lacquer thinner to it and then scrub it with cleaning ball.
2. Detergent used in textile industry will work (Bottled such detergent is called AL). I've tried it. It really works well.
3. Use sulfuric acid. But you should mix it with water before use, otherwise the door will corrode. Immerge the door into the mixed sulfuric acid for a period of time and scrub it with cleaning ball.
4. Firstly, use electric hair drier to heat the film. And then slowly tear it off or scratch it off using small wooden shovel. The marks left by glue can be wiped off with solvent.
