Battery post corrosion
I noticed quite a bit of corrosion has recently formed on the negative post of my battery. I have a gut feeling it was caused by water that must have settled there unnoticed after I did my first engine wash ever at a coin car wash place 2 or 3 weeks ago.
So here's my questions....
1- what is the best way to clean the cable and battery post?
2- what is the best way to keep the corrosion from coming back?
3- when I remove the negative cable, will I suffer any problems to anything important? I realize I'll have to reset the clock and radio pre-sets, but will anything else be affected, i.e. TPS system, etc?
I know this is pretty simple stuff, but I want to go into the clean-up knowing all I should.
Thanks in advance for any advice offered.
