Can't help you with the ice box removal, but if you follow these instrutions (an excerpt from my book), you'll end up with a clean ODORLESS bilge:
1. You can't get rid of any odor unless you first eliminate the source of that odor. So before starting any cleaning you need to find and fix any oil leaks, replace any permeated hoses and remove any other sources of odor.
2. Bilge pads and “pillows” no longer can separate oil from water and collect the oil once detergent or degreasers are mixed with oil. So
before using
any degreaser, detergent or other cleaning product, put them down to sop up all the oil and/or diesel possible. Replace pads/pillows as necessary and dispose of them in approved sites.
3. Scrub the bilges. In my experience, a power washer is the best way to clean a bilge, because it gets into places you can't reach.
4. The most important step: Flush
all the dirty water out! A wet dirty bilge IS a primordial soup! You won’t get it clean by just dumping something into it, then letting the bilge pump dispose of the dirty water, even if you have scrubbed it...any more than you'd end up with a clean kitchen sink if did nothing more than pour some Dawn into greasy dirty dishwater, scrubbed the sink, and then just pulled the plug.
5. Use a shop vac, or dinghy bailer, bucket and sponge to mop up the remaining water, then leave hatches open so it can completely dry out for 12-24 hours. Turning fans on if possible helps to accomplish that.
NOW you finally have a clean bilge and are ready to eliminate the residual odor.
There is a product that I tripped over at a boat show in Seattle several years ago and brought samples home to test. It's called PureAyre and is available from pet supply stores and Amazon too, as well as directly from the company
http://www/pureayre.com and is the
only product I've found that will not only eliminate "organic" (sewage, mold etc) odors, but also diesel, oil and even smoke odors. This stuff
works! Put a gallon undiluted in a pump garden spray jug (unless you enjoy wearing out your hand on a trigger sprayer) and just lightly "hose down" every surface, nook and cranny in your bilges, inside bait/fish boxes, lockers, and any place else that's smelly--including the inside of your boat shoes!--even the inside of the fridge; it's approved for use around food. It also does a great job on cushions, musty foulies and PFDs. But remember: PureAyre is
not a cleaning product! Use it only to remove residual odors
after you’ve thoroughly cleaned and removed all the sources of odors.
Do
not rinse!!! Just leave lockers—including the fridge or ice box, and all hatches etc open for 24 hours. Run fans if possible, and put soft goods and anything else that isn't bolted down out in the sun all day.
