Two words: Pressure washer.
You may recall I used a pressure washer on some interior walls(!).
Well, the walls are painted; now it's time to clean up. Since the pressure washer was still sitting on the walkway, well, why not?
Done it three minutes!
It used to take me twenty minutes or more to clean a roller pan in the sink. Now the job is over before I can recite the Gettysburg Address! Plus, the clean-up is almost enjoyable.
(I didn't try the rollers - they went in the trash.)
