I have this metal box, I believe stainless steel.
As seen in the following photos, this box has many grooves and details. These small grooves are filled with grime, dirt, gum, candle wax, smoke, some sort of stains, and who knows what else.
How can I properly clean this metal box?
I have tried brushing it with water and soap, and also with baking soda and vinegar. Most of the grime has been removed.
