To wax brass for outside use, follow these steps:

1. Clean the Brass: Start by cleaning the brass thoroughly to remove any dirt, grime, or oxidation. Use a mixture of warm water and mild soap, and gently scrub the brass surface with a soft cloth or sponge. Rinse off the soap residue and allow the brass to dry completely.
2. Choose the Right Wax: Select a wax product specifically formulated for metal surfaces, such as brass or copper. Beeswax or carnauba wax are commonly used for brass. These waxes provide a protective barrier against the elements and help prevent tarnishing.
3. Apply the Wax: Put a small amount of wax onto a soft cloth or applicator pad. Apply the wax to the brass surface in a thin, even layer. Work in small sections to ensure complete coverage. Avoid getting the wax on any non-brass parts or surrounding surfaces.
4. Let it Dry: Allow the wax to dry on the brass surface according to the product instructions. The drying time may vary depending on the type of wax used. Do not rush the drying process as it’s essential for the wax to bond with the brass.
5. Buff the Brass: Once the wax is dry, take a clean, soft cloth and buff the brass in circular motions. Apply gentle pressure to bring out the shine and remove any excess wax. Continue buffing until the brass surface is smooth and lustrous.
6. Repeat if Necessary: If you desire a thicker protective layer or deeper shine, you can repeat the waxing process. Ensure you follow the instructions on the wax product and allow proper drying and buffing between applications.
7. Maintain Regularly: Over time, the wax coating on outdoor brass may wear off due to exposure to weather conditions. To maintain the brass’s appearance and protection, periodically clean the surface and reapply wax following the above steps.

Remember, when waxing brass for outdoor use, it’s important to select a wax that is suitable for such conditions and regularly monitor the brass for signs of wear or deterioration.
