Had a friend who experienced a similar experience. Haven’t used a SS grill scrubber since. I use a wood paddle grate cleaner, and a metal paint scraper for hard deposits.
High heat method for the Napoleon gas grill or the BGE. Bring grill to about 600 and scrape away. Once a year I hit my SS grates with the pressure washer. Spraying grates with Avocado oil before cooking will eliminate quite a bit of deposit buildup.

I have a non-metallic brush with stiff bristles. Give my grates a couple passes with that while still hot after cooking. A wad of foil scrapes well also. Before cooking I use oil on a paper towel prior to putting the food on.
I read on here about the wire bristles coming loose. Thought ‘that won’t happen to me’. Until I was getting ready to toss food on the egg and saw something shiny on the grate. Found several loose strands on it. Threw the wire brushes out. Never again.
I put them in the dishwasher. Comes out clean every time
I have been using SS wire brushes forever, I also wipe down the grates with paper towels twice before cooking, no problems.
I burn mine off when needed. I have an egg and let it get to 650-700 for a bit and then put the charcoal out.
Throw grates in oven on clean.

Vinegar and black garbage bag. Spray grates with vinegar while in the garbage bag. Tie the bag tight with grates inside. Set the bag in the sun at least 6-8 house. Over night after a good setting in the sun. The heat and moisture will soften the crud. Rinse and repeat when needed.
Dawn and scrub sponge
Dawn power spray let soak , or high heat wire grill brush then turn over.
