ok. for all guys that keep your boat spotless, what do you recommend to keep slime and lake erie crap off the botttom of your boat? leave the boat in the water for more than 10 hours on the river and the boat gets dirty water lines. also looking for something to keep it off of a large inflatable rib. the back of the tubes are always in the water. it is a pain in the ass to keep scrubbing that off. thanks in advance.
