First of all, thanks for asking this question! A good way to reduce the effectiveness of any LED display is to clean the display with chemicals. Alcohols and other caustic chemicals ruin or obscure the clean panel over the LEDs. A fuzzy, or hazy panel will diminish the impression of your sign. So, what can you do?
Digital LED signs are remarkably resilient to rain, snow, hail, and other types of awful weather. They rarely need to be cleaned. They rarely need to be serviced, too.
