Removing Grease (or whatever it is) From Around Garage Overhead Doors

Anyone know the best method to remove grease from around the perimeter of garage doors when they are closed? It does not come off with the power washer but if you use your finger, it will smudge so it should come off. Do you include removing this stuff with a standard house wash? Also, sometimes there are large black stains (not shotgun fungus) around and underneath window frames and on the siding that simply will not come off. Anyone know how to remove this? How do you usually tell the customer about this after the job is completed if it cannot be removed? Do you have a waiver that tells them about this stuff before the job starts?

Don’t have one myself but a hot water Pw unit should take it off, I believe hot water can mess up vinyl however

Correct on no hot water. Try magic eraser. You can find it at any supermarket in the cleaning isle. It has gotten me out of a few jams

A bottle of “Awesome” (no shit) at a dollar tree. Reads dollar tree on purpose. Other chains may or may not have it. For a buck, we used to clean Hood vents and fans for restaurants with it. Spray on and watch grease melt off. Paint may too, you were warned.

I use diluted chlorine. Wipe it on let it dry 30-45 minutes and rinse

For greasy mess on glass or siding, I will use a mechanics hand cleaner like GoJo WITHOUT pumice
