Here's some corrosion on the relay.  I used a product call Corrosion X that worked awesome at removing corrosion!   I cant recommend it enough.  I sprayed it on and let is sit a night or two before wiping it off.  I used a small Harbor Freight wire tooth brush first and wiped clean.  Works great!!!  

You can get it at Amazon.  Order the pool blue can for big jobs and the red spray can for keeping corrosion at bay.
