Alternator got wet/won't charge

1986, toyota pick-up, 4 cylinder 22R engine with 286000 miles. I think it's a 2.8 litre engine. My power steering pump had been leaking and some of the fluid sprayed onto my alternator so I used an engine degreaser to clean the alternator and then hosed the debris that fell off. Not harshly, just a splash of water. Immediately my dash Charge Light came on and Dash Brake Light andI did this to locate the power steering leak-hose, or pump. The alternator has since tested as bad. Will this dry out? I now have used brake parts cleaner to cleanse and evaporate the area of the alternator. Still, 3 days later, my Charge light is on and alternator is not working. Any advice is helpful.
I placed a previous question but thought I should do so again with the title depicting wet alternator.
Sincere Thanks,
