When working with iron, steel, and aluminum, you should ensure the surface is clean and free of dirt before applying a paint or patina. Sculpt Nouveau's Metal Cleaner works on both ferrous and non-ferrous metals and is specifically formulated to quickly remove rust, dirt, oil, and grease.
Additionally, avoid using solvent-based thinners as they leave a residue on the metal and alter how paints and patinas apply. Download a free safety data sheet for Sculpt Nouveau Metal Cleaner and Degreaser.
