Have you ever wondered what would happen if you smeared Close-Up toothpaste all over your dirty FRP board? I found this toothpaste on the ground and I already brushed my teeth for the week so……
This is what it looked like after I applied the “Whitening Cinnamon Blast” to my FRP board.
I waited 2 days because I wanted super whitening action, not really sure what the white crap comming off the red Close-Up is (first picture). (Actually, I was sick and forgot to clean it up.) But I just rinsed the Close-Up off and presto! spotty white FRP! Worked really well; maybe if you let the Close-Up stay on only 1 day? The conclusion of this study is if you leave Close-Up on your teeth or anything else it should whiten anything up!
I think I see the virgin mary in the area you cleaned.
How much of the toothpaste did it take to clean a Virgin Mary-shaped spot on the FRP? Would it be cost-effective to clean a whole bay? Did you brush as directed or just apply, forget for two days and rinse? If you brushed, was it with circular motions or up and down?
