$600 for a cleaning sounds like a lot to me...but then I'm just old enough to remember when a Hershey bar about the size of a skateboard was 5¢. If you have electric power in the boat lot or a semi-decent 1,500 watt or better generator, I'm a big fan of that little Harbor Freight
PORTLAND 1750 PSI 1.3 GPM Corded Electric Pressure Washer that are on sale right now for the pre-Covids price of just $69.99. I've been nursing along its only slightly weaker 1,700 psi predecessor model for damned near a decade, and must say that it's just
exactly the right amount of "weakly craptastic" for boat and vehicle cleaning without the least risk of blasting off the gel or clear coat. And with a bit of patience it will also scrub a deck clean. Also, instead of spending a bunch on overpriced maritime wonder goops and cleansing potions, just raid the laundry room for some Wisk brand laundry detergent. Ask for it by name, as it's truly a wonder substance long beloved by boaters in the know far and wide for removing those cruds. Just fill up the sprayer bottle in that pressure washer and suds up the rig, allow to stand 15 minutes, and then blast her clean. As for the wax on-wax off portion of your crud combat training, "Horror Fright" again comes to your wallet's rescue with their
DRILL MASTER 1 Amp 10 in. Random Orbital Polisher/Buffer for just $24.99. As for the wax, I like that pricier Collinite paste brand for the major "spiffyings up", but will also touch up from time to time with whatever's on hand, like Meguilar's or some 3M boat wax that I snagged on closeout for like a buck a bottle when the local Gander Mountain went belly up. So basically, for under a hundred bucks you can easily handle this without sending your elbow one-way to Gimpytown.
