What is the active ingredient for this product?

Sulfuric Acid <1.5% by weight. It’s in the MSDS sheets you can Google online. I left it on my black paint for 30 seconds at most. Trouble spots got a second turn. It’s acidic so neutralize with soapy water or detail spray per manufacturer bottle instructions.

Will this work on fiberglass boat?

All I can say is that it works great compared to other products I’ve tried

Can this be safely used on glass coffee carafes?

I have had very bad results with this product. It claims to remove water spots off car paint. It simply does not work. At all! And they do not accept returns …. Very disappointing from a company that has other very good products.
