Sprinklers helped control a small fire at Pearl Cleaners Monday night. It broke out just after 7:30 at the business main office on Third. Fire officials say the fire was due to a chemical reaction from grease on towels being cleaned. They believe that grease reacted with the heat from the dryer. The sprinkler system was instantly set off. Fire crews say the situation could have been much worse if it wasnt for the sprinklers. There was minimal damage.. mainly from the water.
