Just keep in mind that Klean Strip contains methylene chloride, a solvent that is on the "probable" carcinogen list, so you should use chemical resistant gloves, safety glasses and work outdoors to keep inhalation as low as possible. There are also acute toxicity issues if exposure levels are too high.
Here's the Safety Data Sheet for it: https://www.homedepot.com/catalog/pdfIma...669423.pdf

You don't need to be afraid of it, just be smart about using it.
