detergent and fresh water.
Biological material which is strongly rooted in the substrate can be removed
carefully with a piece of wood or plastic.
If required, you can also use citric acid. Apply, leave it working for several hours,
and rinse thoroughly with fresh water.
Note
Do not use high pressure water, sand blasting, metal tools or strong solvents to
clean the sonar head face.
Do not damage the outer protective skin on the sonar head face.

If you find suspicious damage, take high resolution pictures that show the damage,
and contact Kongsberg support for advice.

Note
Because some paint types may be aggressive to the polyurethane in the sonar head,
