Spray on disinfectant/bandage

Artist put a spray on antiseptic/bandage over my tattoo. Said saniderm doesn’t work out the outer calf. They’re two fine line tattoos, size of palm, if not smaller. The bandage is still there… how do I get it off? It’s flaking like dried sunburn but it won’t all come off. Washed tattoos a few times but not even sure if I’m washing the tattoo yet or still just bandage…. Help! How do I get this off!
