Stain remover instructions for use

Ultramar’s Power Cleaner removes stubborn stains and ingrained dirt from your boat cover. Use this intensive cleaning agent as follows:

  1. Apply the Power Cleaner to a dry boat cover. Brush the cleaning agent into the canvas using a soft brush.
  2. Leave the Power Cleaner to soak in for approximately 1 hour.
  3. Don’t notice any change? Use extra Power Cleaner, brush it in and leave it to soak in again. Repeat these steps until the stains have disappeared. This may take several hours.
  4. Once you are satisfied with the result, rinse the fabric thoroughly with clean water.
  5. Allow the boat cover to dry completely before storing it


After use, treat with a strong impregnating agent to waterproof and protect the fabric.

Power Cleaner is a super strong cloth cleaner. You can use Power Cleaner on almost any fabric. Always test on a small inconspicuous piece of fabric first. On some tent fabrics, especially cotton and canvas, Power Cleaner can have a slight bleaching effect.
