During our research of sonar screen, we have found that the most damaging thing to the screen itself, is not keeping them clean. Dust and dirt mixed with pollen from trees and plants forming on the screen and at some point coming in contact with moisture or water make a highly acidic mixture that can damage your sonar screens. You may have seen some sonar screens with bluish or greenish circles that are difficult and sometimes impossible to remove. This is very annoying and hazy to look through when viewing the screen. The Bass Boat Saver Sonar Screen Cleaner is designed to remove all forms of dust, dirt and pollen quickly and it also contains an anti-scratch polymer to keep your screens from becoming scratched or damaged during the cleaning process. The formula does not contain alcohol, ammonia or damaging solvents. It is designed with highly purified surfactants and low active cleansing agents to clean and protect acrylic screens.
