Pressure washers come in two fundamental designs…either hot water pressure washer or a cold water pressure washer. Once you determine if you want to use hot water or cold water, then more choices come into play, regarding fuel types and mobility. But for now, let’s look at the difference between hot water and cold water models. If you’re not quite sure which type you need, consider the following:
Cold pressure washers are ideal for removing dirt. However, if the surface you are cleaning is mixed with oil or grease, a cold water pressure washer won’t clean as well as a hot water pressure washer.
Think of it like washing greasy dishes in the sink. No matter how much soap you use, you are only smearing the grease around in cold water. Add hot water, and it cuts through the grease and oil in no time. The same applies to cleaning with a pressure washer. If oil or grease is present in any form, you will need a hot water pressure washer to remove it quickly.
