Eric.....SOAP AND WATER!!! Eagle one products are horrible and cause spotting and all sorts of problems.

Yes I know some of you use them and for some applications....it can be done.
In your case I would say if warm soapy water doesent work...try some lightly diluted Simple Green. Dont let it sit long. You could use Dawn dish soap if you wanted to go a little stronger on the soapy water thing first.
