If you have overheated, by using a fierce oxidising flame, or even prolonging the time, you will get a bluish patch just below the surface, commonly called firescale, which is difficult to remove without fierce abrasion, so is best avoided. Painting all over with a flux first, helps to reduce the likelihood.
Brass brushes used wet and soapy are common in jewellery and leave no discernable residue, or reaction by the wearer. Used dry they leave a nasty stain. Many of my chains and textured pieces are finished by this method alone.
Thank you for liking the acrylics. There is a reply posted for you. Dennis.
