Koch Chemie Insect & Dirt Remover. Similar to Green Star, this alkaline cleaner is simply sprayed onto bug guts or a dirty area, and the issue can then be rinsed off. It may be used at the maximum strength (as shipped) or may be diluted to customer preference.
Because this is an alkaline cleaner, care should be taken with the environment in which it's applied, and work time kept to a maximum of 5 minutes to ensure there is no unwanted surface interaction. After being applied, the insect debris and dirt should be rinsed off of paint. Glass may be wiped off with an appropriate microfiber towel.
