Guardian products 'Solclens' could go in spots 1,2 or 3. The best product I have ever used. I've been using it since 1985, and it has never failed me. Interiors, exteriors, engines, wheels, arches, cookers, bathrooms, upvc windows. You name it, Solclens will clean it. And it's food safe. Dilute from 1:10 for the toughest make, down to 1:100 for general cleaning. It is all I ever use for interiors and for use in the upholstery machine. Search Guardian Products Barnoldswick.
