A Dexter-Russell spatula with the straight leading edge and non-sharp corners is perfect for this,
and with the added benefit that it doubles as... a spatula!
Amazon sells them also.
Exactly, that is what I use. The Dexter-Russell is the best, and normally a soft brush along with some hot water does the job. But when I screw up royally, the chain mail does work a treat, just get a good one. I also found a good use for the flax oil that I initially bought for seasoning. It works well for the handle on the spatula, it is after all, food grade linseed oil
