I had a mobile service done in my garage because the driver side washer does not squirt fluid. Service tech pressed the stick a few times and quickly diagnosed the assembly folk did not connect the fluid hose. Push it in and it worked immediately. Easy fix. However, after I backed out the car, I have several puddle of blue liquid on my light color epoxy coated floor and it won't come off. Normally people do not activate windshield washer in their garage but in this case, I was wondering what to use to get rid of the stain.
