William and Lorna,
Your posts reminded me of my frustations in the 70’s when I had a fiberglas ski boat. The boat was left in the slip in the winters and the water was extremely hard. The result was that in the spring, it had to be hauled out and the hull cleaned and waxed. We went thru the whole list you mentioned and nothing was really effective. Finally, a neighbor worked for a company that made a product called “DELETE”, recommended that I give it a try. It worked great until it could no longer be found. He left the company and moved.
After more searching, I discovered your recommendation “ZUD”, and found it worked as well as Delete. Both these products had the ingredient, oxalic acid, in them. This was the bleaching agent.
The stain had penetrated the surface of the fiberglas down into the material. The oxalic acid went after it and bleached it out. It was astonishing.
Zud went on like Comet or Ajax, and then was left 30 minutes to an hour for the acid to work, then cleaned or buffed off.
Both of the above products worked well in the described situation. It took a lot of elbow grease and time. Also, you are warned to wear some type of kitchen gloves. It will take the hide off.
