So the kid left the PTO shaft for the rotary cutter laying on the ground a couple of weeks ago when he removed it. It rained, rained and rained again, splashing the sandy dirt up and into the coupler. Not sure how to get all the dirt out of there. I don't think I have a brisk that small.

Anyone have experience in such matters?

Here's a couple of pics

Some penetrating oil and a tooth brush, acid brush and maybe a bottle brush. No single brush will reach all areas and something like PB Blaster, WD-40 or other thin oil should do the trick.

Yup, this works, and maybe a toothbrush size stiff wire brush for difficult spots, been there done that.

When I bought my wood chipper the PTO shaft looked about the same. I hit it with the power washer, sprayed it down with liquid wrench and scrubbed it with a small wire brush. After 30 minutes of toying with it, I sprayed it all down with carb cleaner, let it dry and then sprayed it with fluid film. Haven't had any problems with it since

It's just steel. Pressure wash if ya got it, or hose, etc. Take the shaft to the local car wash and hose it down for a few bucks.

WD40 is a great cleaner, better at that then lubricating LOL.

I bought a set of detail brushes from Harbor Freight a few years ago. Some are wire brushes and some nylon. I鈥檝e used this set countless times for stuff like this along with PB Blaster.

For $2.46 even at today鈥檚 price its a no brainer to have a set on hand.

plumbing brushes for cleaning before sweating have come in handy for lots of stuff for me besides plumbing CU. Sometimes I cut the loop off the handle with lineman鈥檚 pliers and chuck it in a cordless drill to spin and clean. In addition to a compressor, I keep a shop vac around when I鈥檓 cleaning the inside of mechanically engineered objects.

I would suggest kerosene, break cleaner or like liquid..
Several pipe fitting brushes like shown in post 14....

Then dis assemble the retractable ring, spring and locking balls to clean individual ports...
Lube dripping wet with silicone spray when re assembled...

I had to do this with a couple new pto shafts that looked like the ends had been dipped in a gummy black paint...
It is quite hard to scrape thick black paint off 10 mm steel balls...

Spray with wd40 and then use a brush like everybody suggested. If you have compressed air, use that before spraying with oil. After it's all clean, spray with fluid film. I learned about fluid film on this forum and it is wonderful for pto shafts.

I agree, pressure wash it, then grease the U-joints to force out any water, then spray the spline area liberally with WD40, which is what the stuff is designed for. Water Displacer, 40th formula.
