Yes - our aluminum signs can be effectively washed with a mix of detergent and water. Be sure to rinse completely after cleaning. If you’re using a more abrasive or chemical cleaner, test the product on a small portion of the sign to prevent damage. Any cleaners using chloride, acetone, or other such chemicals should be avoided.
If your sign has been vandalized by spray paint or permanent marker, we recommend spraying the stain with isopropyl alcohol and letting it sit for a minute or two. Then use a soft dry cloth putting pressure on the stain to wipe away. Repeat as necessary.
