to August Race RIB cleaner and conditioner. Sort of expensive but I bought it from Defender during one of their weekly half off sales. This stuff works! Spray on and wipe off. My Air-deck floor has been trashed with otter sh#t and other stuff for several yrs. Tried numerous things from goo gone to citrus to acetone etc to clean it up without success. This stuff cleaned it up fast. No longer sticky and nice looking. I’m a happy camper (sailor).
