It’s safe to assume you already know the difference that hot water makes when cleaning dirty dishes. When things get hard to clean, you crank the heat up. So why do so many exterior cleaning businesses use cold water pressure cleaners for the outside of your house?
My first guess why a business wouldn’t clean with hot water is cost savings, but that doesn’t make sense. To achieve the results of a hot water pressure cleaner with cold water you need a whole lot more pressure. This would certainly expose the business to a much higher risk of damaging surfaces, which doesn’t sound cheap in the long run. Perhaps they do it to lower maintenance or running expenses, as hot water machines use a lot more fuel. Or maby they don’t have space to transport the larger machines – I’m grasping at straws here.
Whatever the reason is I’ve yet to figure it out, it’s a blatant cheat code for any business that jumps onboard. We’re able to impress customers with our ability to actively kill exterior mould thanks to the 90° water. We also use significantly less pressure which keep us clear of liability. It’s easier for the operator, does a better job, and cleans faster which means less water usage.
Put simply, if I was a homeowner looking for exterior cleaning in Melbourne, this would be the first question I’d ask: “Will you be using Hot Water to clean?”. Or you could hire Newshine, because we don’t even own a single cold-water pressure cleaner.
