How can I remove paint from stainless steel?

This the case:
My paint consist of a mixture of acrylic silicone resin, epoxy silicone resin, and melamine silicone resin (at least that's what the mill sheet told me)
I applied that mix to stainless steel surface and bake it at 150 °C x 30 minutes
Sometimes the paint applied shows bad appearance, so I must repair it.

The problem is I can't find a chemical to break that paint layer from stainless.
The paint sticks too well. Right now, we just throw the un-repaired items in our garbage can.
Can you tell me the right chemical solution for this case?

Having worked in the trade for 30 years I find the best way of removing the paint is by blasting with a soft sand and water.
