On a heavily greased dumpster pad or drive-thru lane, a hot-water machine visibly outpaces a cold one.<\/p>\n<p>Heat adds nothing meaningful on organic growth, general grime or concrete cleaning, which is chemistry-and-pressure territory. The advantage is specific to petroleum and food grease.<\/p>\n<h2>How cold water closes the gap<\/h2>\n<p>Degreasers do with chemistry what heat does with energy: break the bond between grease and surface. Given proper dwell time and repeat passes, cold-plus-degreaser reaches comparable results on all but the heaviest accumulations \u2014 it simply takes longer.<\/p>\n<p>On a maintenance schedule the gap nearly vanishes: recently deposited grease releases readily either way. The scenario where hot water clearly wins is rescue cleaning of long-neglected grease \u2014 which a schedule prevents from existing.<\/p>\n<h2>The honest bottom line<\/h2>\n<p>We run cold water and compensate with chemistry, dwell and passes. On maintained sites the result is equivalent. On a badly neglected grease surface, expect the first visit to take longer than a hot-water crew would need \u2014 after which the schedule keeps everything in easy territory.<\/p>\n<p>Ask any contractor what equipment they run and how they handle heavy grease. The answer tells you whether you are hiring a method or a pitch.<\/p>\n<p><em>Heavy grease situation?
