Yes, you could technically test a different paint stripper, though I haven't tested any of them to give a recommendation. I like the Citristrip gel because it has a much lighter scent, is easy to keep put because it’s in gel form rather than liquid. If you’re comfortable with another type of paint stripper, that’s fine. Just pay attention to the instructions on the container about how long it needs to set, and make sure it doesn’t drip onto the rest of the tumbler.
