White gel stained from water at race

[rjdubiel]

finally need to clean the viper, white gel and it has a black stain from some oily waters at three lakes. I got most the heavy off but need to either polish the rest off or something. Would On Off hull cleaner be the choice or are there less aggressive products out there. I used dish soap to get most if it off but even gas does not get the stain completely off. Never had to use anything aggressive on previous boats, but none were white and used the other boats in cleaner waters all the time where cleaning was not really needed. Most the mess usually is from the road!

thanks

Try Works tub and shower. I used it on mine and the hull was yellow from water stain now bottom shines like the top and mine is white as well.

Go to aircraft spruce website,look for a product called carbon X use as directed it will come clean.Used to remove Exhaust or any carbon based stain from aircraft,used it for years.Im sure it will remove carbon based stains from gel coat.
