I hibernate my box always as "exhibit" in the entrance area of our company, as it has to look natural wonderfully clean. And that you get with this cleaner such easy and quick to point that one can only be amazed. Spraying, leave on, spray off, finished. Of course you have at all stubbornly adhered dirt or mechanical help out, but that's just a no brainer. The machine looks like new in no time, wonderful!
