Windex multi-surface with vinegar.

Using ammonia based cleaners on LCD screens is bad.

Wave Away works great.

(Sprayway) worlds best glass cleaner ammonia free and sreakless

ok now i have heard this thats why i want too know what is safe to use. Guides chime in too

i had to clean up some old hbird graphs and the windex wasnt cutting it. So i used some light scratch compound and a white buffing pad, used my air dye grinder and whola!!! It looked brand new!!!

Humminbird recommends this for their unit screens:

I use the windex ms vinegar and microfiber towel. There is probably something better but it works for me. It does sometimes leave streaks or spots in the corners if im not taking my time.

Stacey King on an old episode of the Bass Pros suggested this... get a paper towel. Then lay it on the screen and spray distilled white vinegar on the paper towel. Leave it for a minute or so then pull the paper towel off. Use a microfiber cloth and clean off the vinegar. Then if needed use the
recommended Windex with Vinegar to put the finishing touches to it. This truly removes the water spots. Good luck and good fishing!

Bacardi

1/2 water and 1/2 white vinegar with one drop of dawn dishwashing soap in a medium spray bottle. this is cheap and works better than anything I have seen.
