10/09/2015 How to clean up and return that new, never-needed, starter for a full refund?

Hi, y'all!

Thank you for your earlier help and support.

NOW, I need to return the new starter that
was installed, used for about twenty miles,
and replaced with my new/old (< 200 miles
on it) Bosch starter.

There is a 1 1/2 " oil smear on the white
paper label, and general grime on the
metal portions . . .

How Would YOU clean it back to apparent
"newness" and return it for the $125 refund?

(At time of purchase, last week, the clerk
said I would not be able to return the starter
IF it had been installed . . . )

Help, please; I want to return this albatross
and get my $125 back!

Thank you,

Linda
