P21S® Polishing Soap allows you to spend less time cleaning and more time boating!
 
Soak them in vinegar for a couple days.
 
I put Mary Kates On&Off in a spray bottle and spray and let it sit, and then scrub with a scotch brite or sos pad. Be sure to use rubber gloves, goggles and do it outside. Then rinse them and repeat the real bad spots if you need to. I am removing mine obviously when doing this. It works well, I am in fresh water also, 5-6 months out of the year.
 
I’m not recommending you do this, just saying what I do.

When I’m cleaning the hull bottom with muriatic acid I spray some on the stainless steel propellers then rinse with water. They are clean in seconds.
 
I don't get it. We don't even know if they are rusting, barnacle encrusted or have dried seaslime on them. How do you guys know what to advise to clean when Brian hasn't answered my first question?

There you go asking the correct questions so you can help someone with the right answer.
Would you please cut that out Todd? (kidding you my friend)

To answer your question, I said what I do. I don’t even recommend it. However as a side benefit my nasil passage has never been more cleaned out then when I use that mir acid.
 
use ON/OFF and acid cleaner for drives its has some muratic or hydrochloric acid and a mix of oxalic acid a good pressure washer helps out a lot use protective gear for this that acid burns

Sorry Todd. My bad. I should know better. I appreciate everyone's help. I tried using the search feature but had no luck. Than I remembered the name "Naval Jelly" and was able to find something.They look just like CAPZ pictures. http://clubsearay.com/forum/showthread.php?t=6652&highlight=naval+jelly
Last year I used CLR and a strong wire brush but it took forever and was very labor intensive. I am leaning towards the Naval Jelly. Yes, No, Something less powerful? More powerful? Thanks for everyones advice so far.
 
Well Brian,
It looks like it is a baked on seaslime. Have you tried taking them off the outdrive(to avoid damage) and pressure washing them? If not, and now knowing what you are trying to get off, the On/Off product may work very well.
 
I just cleaned my Bravo III props by soaking them in a diluted solution of On-Off. I hit the tough spots (barnacle remnants etc.) with bronz wool and/or a weel brush on an electric drill. They look great, but while working on the pair I found a 3/4" hairline crack on the trailing edge of one of the blades. Off to the prop repair shop :(
 
I am with Todd on this one not knowing exactly what they look like. Having said that a good old fashioned green pot scrubber and some Barkeeper's Friend will probably get off just about anything and in short order except for maybe encrusted barnacles.

Just spray on muriatic acid then rinse with water and they will be clean.


Get muriatic acid at a fleet farm / farm supply store. Less than $5 for a gallon and you will only need a little.
 
I'm with Dave on the green scrubing pad and bar keepers friend, but I have used comet on mine before with the scrubing pad too. If you really want a polished finish you need to get a hand held die grinder with polishing pad/sponge. The little pads are like soft like sponges and do the trick on stainless finishes if you want that fine of a shine.:thumbsup:
 
It seems like props used in fresh water are much easier to get cleaned than in salt. I tried the Naval Jelly and it helped...somewhat.... but the Marina was cleaning my dock neighbors props and the stuff he was using was absolutely amazing. Mary Kate ON/Off hull and bottom cleaner. Brush it on and hose off. It only requires a small amount of effort with a Scotch Brite sponge on the barnacle rings. He let me borrow it. Incredible how easy it was compared to the other stuff I tried. This stuff is heavy duty and you should definitely wear eye and skin protection when using it. Thanks to everyone with their help and to those that suggested Mary Kate....Right on the money. http://store.hamiltonmarine.com/bro...ttom-mary-kate-on-off-32-oz-123145/4,681.html
 
I don't do anything.......... The darn things are underwater all season. Who cares if they aren't shiny. Even if they were shiny in the spring, they'd be cruddy within 1 week of going in the water.

See Todd an answer that did not require the OP to splain anything more!
