I would use kerosene, goo-gone, white gas,
paint thinner for oil based paints, mineral spirit, turpentine because they tend to be benign on polyester polymers. Lacquer thinner or acetone will dissolve polyester or swell crosslinked polyester (gelcoat) under long exposure.
I have seen people using acetone to clean boats and with limited exposure the potential damage to gelcoat is likely invisible.
