Things You Should Avoid Doing When Cleaning Your Fish Finder

Cleaning a fish finder is not like cleaning your window panes. The modern fishfinder monitor comes with anti-reflective coating technology so, using any abrasive cleaner can end up damaging it for good. The abrasive cleaner can wipe off the coating on the monitor just like sandpaper would do.

Also, using a paper towel to wipe the screen would be a bad idea, as they have fiber which can create scratches on the surface. You wouldn’t want to use alcohol or ammonia to clean the display as they work as a solvent to dissolve the reflective coating. 

You might find them useful in getting rid of the water spots but, long-term use will damage the anti-reflective feature. 

This will make the feedbacks almost impossible to see if it comes in contact with sunlight or any other ambient light. From time to time, the screen will start to cloud up, and making it useless at a point.

Some people may suggest you use Rain-X to clean the screen but avoid those at all costs. They are made with polymer substances so, they might cover up the anti-reflective screen. As a result, you will lose the anti-reflection feature.
