Cleaning an Acoustic Ceiling
Acoustical tile ceilings act as "sponges" for sound, soaking up excess noise to create a more pleasant environment. Unfortunately, these tiles also absorb airborne dirt, grease, cigarette smoke, nicotine, and bacteria, making ceilings dirty. Professional cleaning solution can break down the dirt film into micro-dust particles that evaporate into the atmosphere and are filtered away through the air handling system.
Acoustic tile ceilings can usually be professionally cleaned
for about 20% of the cost of replacement and 50% of the cost of
painting. Regular cleaning assures the uniform appearance of your
ceiling for years to come.
Partial replacement of ceiling tiles results in a "checkerboard" look. Painting is messy and it can destroy the acoustical value and can alter the fire rating of your tiles. Cleaning ceiling tiles retains these qualities without leaving a lingering odor.
