We have our own hot wash Steam Cleaning Equipment and all of our operatives are fully trained in the use of the industrial deep cleaning equipment.
There is a difference in the final outcome. You want to clean not only the dirt and grease, but also any other existing bacteria. The UK has problems with moss and lichen. While cold pressure washers are ideal for removing dirt, they are completely ineffective in killing the medium in which these two challenges grow. The hot water system kills the existing bacteria as well as ensuring that re-growth is slower.
In addition, 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, only a hot water pressure washer will remove it quickly.
A final annoying challenge is cleaning up chewing gum – hot water will simply melt the gum off the paving, making the area clean and safe. Using cold water systems is completely ineffective. Hot water pressure washers clean faster and better, saving time and getting your building back to normal in less time, making customers and residents happier.
