Default Cleaning Hypalon dinghy?

Our brand new (well, two years old now...) dinghy is looking a little dingy.

Does anyone have any suggestions for cleaning a hypalon dinghy? Will
bleach hurt the hypalon?

Note that cleaning materials that work on PVC (or decitrex) may harm
Hypalon and vice versa. I am interested in hypalon cleaners...

Also note that I have been specifically advised to avoid cleaners which
contain silicones (eg ArmorAll) to minimize problems with future patches

Hypalon (chlorosulfonated polyethylene) is chemically compatible with
many cleaners. However, the question is more, what is it you want to
"clean". "Dinginess" is typically due to structural degradation, not an
foreign substance, so cleaning doesn't help. This can be confusing
since a lot of coatings that get "dingy" (paint and gelcoat) are
restored by "cleaning" that is not so much cleaning but polishing out a
fresh surface. But rubbery stuff like Hypalon doesn't polish out.

Bleach is often inappropriately used as a cleaner, for which it has an
exaggerated reputation. The actual chlorine oxidizing power is
typically not effective in cleaning, if for no other reason than the
dilution is incorrect (needs lowered pH to activate), and most cleaning
tasks require surfaction, not oxidation. Liquid chlorine bleach (sodium
hypochlorite 5 percent in the laundry version or 10 percent in the
swimming pool version) is typically stabilized with high pH via a good
dose of lye (caustic soda, sodium hydroxide) in the solution, which is a
very harsh alkali cleaner, if not diluted too much. The popular notion
that bleach is a good cleaner is misunderstood, because what really is
typically doing the cleaning is nothing but plain old lye.

I agree with Ed - make a paste with Soft Scrub and a little water, apply
with a scrubbing brush and let dry in the sun for a couple of hours. Then go
over it with the brush and more water and rinse off as you go. I then spray
Aerospace protectant on after it dries.

Cheers

Some agreement points and amplification:

My dinghy service (also the life raft servicer on the free raft I gave away)
joint makes them look new by doing a thorough scrub with acetone and 3M
scrubbie-with-a-handle, followed by 303 protectant. I expect they also
first "clean" it - my most successful cleaner was Purple Power; Simple Green
has not proven itself to me, this included, in *any* environment, to be
superior to nearly anything else I've tried. My first scrub was SG, to
little avail; just spritzing on PP gave rivulets of added clean spots, and
the scrubbie made it white. However, without solvent level cleaning, and
sealing/protecting, it went back to chalky very quickly (months). Back to
the Acetone/303...

Amazing transformation; we'll do it on ours once we actually get close
enough to splashing for Lydia to join me on the boat. The usual avalanche
of photos will follow :{))

Thanks Skip - I will see if I can find this "Purple Power" locally. But
I think I will skip both the acetone and the 303, which I believe
contains a silicone oil of some kind...

Default Purple Power (was) Cleaning Hypalon dinghy?

You can find it in most automotive stores. If you're going to do any
more than spot cleaning (I used gallons on my bilge, e.g.), get the
sprayer quart, or if you have a sprayer, skip that part and go straight
to/also get the gallon refiller of spray quart (or yours).

I've tried umpteen degreasers and none has done the job this does. Use
gloves and rinse thoroughly, don't get it on paint (unless you're
trying to remove it), etc.

Doesn't hurt gelcoat, fiberglass, etc. Think drain cleaner...

Skip, back on the boat

Purple Power is available at Auto Zone stores around here. It is a
good cleaner but over time it will create a horrible stench in your
bilge if even a tiny trace remains. Multiple fresh water flushings
after each use are an absolute necessity.

Just came across this thread. I have a 2001 white Caribe RIB which needs periodic cleaning. I've had the best luck with The Amazing Rolloff, sometimes combined with Soft Scrub Gel w/bleach. I apply both with a Porter-Cable random orbit polisher fitted with a stiff bristle brush. When clean and dry, an ample coat of Aerospace 303.
