I have a few copper accents on my house that have turned black. The Jax Green Patina product says it is permanent. If I use it and don’t like it will I be able to bring it back to bright copper again. Also, do you recommend a cleaner and then a sealer?
All Jax blackeners, darkeners and patinas can be removed with steel wool or Scotch-Brite. You can apply the Green on top of the black you have now for a more authentic finish (the copper should be cleaned of grime (nature), and have no wax, oil, lacquer or grease on it. Or you can remove the black and apply the Green directly to the bare copper (more work, try it with the black first to see if you like it). We would use Dawn to clean everything first. We would not seal it (we think it causes more headaches later on.)
