This brush is aggressive on cooked on food, but doesn't do any damage to finish of any kind.
This brush so easy to clean! Just throw in n the top rack of the dishwasher and occasionally take an old toothbrush to scrub any stuck on bits
I originally have been using those little plastic scrapers to clean my cast iron but they never seemed to do the job completely . I found this product ,the very first time using it I asked myself where has this been all my life . It is extremely sturdy and the bristles are made of a strong plastic that made the clean up easier and quicker than I ever expected !
It cleans the pans well and can also be used on the outside grill.
On indoor meat grilles big plus gets into groves
