Here are the steps to use a copper brush to remove stubborn stains and scratches and polish the surface of the ski/board:

1. First, use a soft bristle brush to clean the surface of the ski/board and remove any dirt or dust to ensure that the surface is clean.

2. If there are deep scratches or stubborn stains on the board, use the copper brush to gently brush back and forth a few times on the scratches or stains to remove them.

3. If you need to polish the ski/board, use the copper brush to gently brush back and forth in the direction of travel until the surface is smooth.

4. Note that when using the copper brush, you should be gentle to avoid scratching the surface of the ski/board or scraper.

It's important to note that using a copper brush may cause some wear and tear on the surface of the ski/board, so it's recommended to use it only when necessary. Additionally, it's important to be careful and avoid letting the brush slip out of your hand while using it for safety reasons.
