Because we are now well equipped to keep it clean.
Seriously, I never knew that this common kind of scrubbing brush, with its squarish head and straight or slightly curved handle, is properly known as a “gong brush”.
A full fifteen minutes of serious Googling were insufficient to uncover the story behind this interesting name. I wouldn’t think that gongs need too much scrubbing- once over with a microfiber rag and the occasional polishing should be sufficient. This gong brush is designed for heavier duty.
For messes at a distance (or extra long gongs), try the Extra Long Gong Brush.
