copper solvents

what kind of detergent do you mean, laundry, dish, pinesol, etc?

Doesn't matter much. Dish detergent, shampoo, and liquid hand "soap" are all the same thing, give or take a few additives. The simplest, cheapest thing you can find will work. Uncolored and unscented are probably a little better. Pinesol is something else. Don't use that.
