Battery Terminal Corrosion that is. I have tried spray on battery terminal cleaner, removed ends, wire brushed posts and ends. Replaced them and sprayed with batter post sealer (red stuff) all to no avail. I've cleaned with cola, baking powder, just about anything that someone suggests all hoping for this to stop.

I don't mind cleaning the corrosion off, it just gets aggravating. In my situation it always seems like the positive side is always worse. Thanks in advance for your help.
 
Clean it up then put some grease around where the post comes out of the battery then put the cable on and grease it whole area
 
ditto what old said.

clean up the terminals good, clean the battery top. clean the cable ends and wires.. IE. make sure all are clean and neutralized. then greas ethe posts, grease the clamps.. bottoms too, grease any exposed bare wire. add clamps, tighten, some grease will ooze out. re-apply grease to cover all metal.

that should end your corrosion problems till the grease wear/weathers off... just reapply.

grease helps shed water and blocks air...
 

You might also want to check the charging rate. Might need to adjust the voltage regulator a wee bit. An over-charged battery will vent gases, which results in corrosion.
 
Could be the post is cracked loose from the case letting gas and acid come up around the post. Not much you can do other than clean it up and pack it with grease.

If it's on a tractor or off road equipment, the rough ride will cause acid to splash around inside more. If it's a serviceable battery, try running the electrolyte level below the rings, just enough to keep the plates covered.
 
The baking soda is good to use. Your cleaning would last a little longer if you would use a terminal spray protector each time. The only way to eliminate the corrosion completely is to get a new battery.
