I can guarantee you she is using yours to clean the toilet.

We use Baby Shampoo or a mild known dog shampoo. I wouldn't think Simple Green would be good for that since they caution you about cleaning real good after using it on their kennels. But like Gus on the Greek Wedding movie that uses Windex on literally everything, I can imagine proponents of Simple Green doing that too.

I had some work done at a dealer that I couldn't do myself and while it was there decided since I liked the tech I'd throw some more work at it. I had him pull the heads and clean up the cylinders and install new rings. Meanwhile I took the heads home, stripped the paint and re sprayed the black wrinkle finish, and heat cured them. Gave them back and when it was time to pick tge bike up it had been "detailed" by some grunt kid with Simple Green. My newly painted heads had white streaks all over them. The entire bike did actually. I will never use Simple Green.

Right. I didn't ask them to do it.

HD engine brightener is not really a cleaner you more along the lines of Pig Spit copy. S100 you need to be careful it can spot the silver engines and fade the Black ones. I said CAN. Not will in every case.
Dawn is a high alkaline soap Like some car washes. The ones that often say use 1 OZ to a gallon, two if it is real dirty more if it is worst. It strips wax off you bike if you want and used right causes no harm.
Mix it to strong and let it sit to long it can cause spots the may never go away on some engines.
