We’ve been giving BEOWULF a good cleaning and polish. This includes all of the engine room (even the bundled plumbing and wiring) the dinghy, inside of lockers, and interior hull surfaces. Except for the dinghy, which has stains on the inside from spilled gas/oil mix, and the engine room, which has not had a thorough cleaning in three years, most of the cleaning is a simple wipe down.
But for the dink and engine room, stronger measures are required. As a result we’ve done some scientific testing of various cleaners. Simple Green, Zep Purple, and Nature’s Orange, in concentrated and diluted ratios have been used. The result…(roll of drums)…Zep Purple is by far the best cleaner. Simple Green is second and Nature’s Orange is last.
The Zep Purple is a wonderful material in the engine room. Diluted at 3-3 we spray it on, do a quick brushing to loosen things, and hose off the dirt. We’re not sure about availability, but we picked ours up at Home Depot.

Zep Purple wins Beowulf’s seal of approval.
