I can only urge testing it well. In my experience there are several types of 'staining'...obviously color staining, where the color of something remains behind. But then there is what I would term 'chemical' staining - where the substance cleans up, but alters the surface...maybe makes it more or less glossy, makes that spot more or less prone to weathering, etc. An example would be spilling clear varnish on a piece of wood...you can wipe it right up and for a while it will look normal, but over time, the untreated wood will begin to age/weather, while the varnish spill will remain somewhat protected. I would also suggest you might have 'ghost' staining - ever take down a picture in an old house and notice a clean spot behind the frame? Sometimes in the act of cleaning something up, you leave an 'inverse' stain of 'clean' behind, which may then prompt you to do way more cleaning than you had intended!
Anyway, good luck!
