Default Softening rock hard rubber

I've watched all of the U-Tube videos and read/heard all of the sales pitches of various products and am understandably thoroughly confused, which at my age ain't unusual. What have YOU used and with what short/long term results?

Or picture a guy with a soft noodle in one hand and a piece of hard rubber in the other hand, who still can't post a picture

If it doesn’t liquify that soft noodle, it might be ok for rubber. You try it first.

I am replacing the water pump in my 50 year old tractor and both hoses have been soaked for years by a leaking power steering pump. Both hose are in excellent condition and are so soft and pliable I wondered if they were replacement silicone hoses, but PO says no way. So, how about soaking in PS fluid? And as for the soft and hard discussion I knew it was only a matter of time for you boys~!......

I have thought about that. Still considering it. I found a good length of old hardened rubber garden hose I'm gonna experiment with.

Soaking in automatic transmission fluid works occasionally.

Back in the time when we used to use gasoline as a lubricant to sand lacquer
color coats prior to buffing and polishing, rubber squeegees were used as part of the process.
If you left a squeegee in a bucket of gas overnight, the next day the squeegee was like a limp noodle.

Do you recall if the squeegee returned to "normal" after it "dried out"? I'll have to give that a shot. I've got to drain the tank on Apatchy anyhow, so I'll give it a shot.

The squeegees were, after soaking, rendered useless for the purpose but
as I recall remained softer than they originally were.

I have just been trying to follow your lengthy dissertation to me about posting pictures, DD. 'Nuff said.

It must be remembered that any and all of the products mentioned in this thread are solvents, and as such, will break down the composition of rubber as manufactured. In that less than stable condition, rubber becomes soft and gummy. Some solvents are better than others for use with rubber. The rubber industry uses toluene, which freshens up cured rubber that is to be rebonded, such as tires with recaps. If to be bonded, heat and pressure is used. If used only to freshen the surface, the end result will initially appear and feel as new, but is in fact a degradation of the original surface.

What Alan said in post #10.
Common bleach (sodium hypochlorite) works sometimes. We used to soak our qualifying tires for the midget in it before it was illegal.
