Low Pressure Cleaning
Over the past 30 years, I have talked to thousands of people, answering their questions and assisting them in their cleaning needs. The inquiries I received 30 years ago are the same as today. People are confused on which is the most effective and safe way to professionally clean their home. To help clarify the differences between external cleaning methods and their Pro’s and Con’s, I have devised a list. I hope this clears up a few of myths.
Types of External Washing
- Low Pressure Water Saving External Home Washing (Recommended)
- Hand Wash (This method is acceptable providing high pressure is not used to wash off.)
- High Pressure Wash (Not Recommended)
- Low Pressure or High Pressure hose on hose off wash (Not Recommended)
1. Low Pressure Water Saving External Home Washing
This is our recommended method. It takes into account all the important elements for the safe and quality service that you require.
- It uses the least amount of water possible for an efficient Home Wash!
- Low pressure (around garden hose pressure) this method assures that water does not pour in through the windows or rip off paint, as it has the potential to do with most High Pressure methods.
- This method also uses safe, biodegradable detergents and chemicals to kill mould and emulsify dirt and grime. Every board is brushed with a soft broom and rinsed clean, leaving you home looking clean and fresh.
- All External cleaning methods leave your windows in a mess from the detergents and chemicals. In this method, all external glass will be squeegeed leaving your glass free from chemical and detergent streaks and spots.
- Screens will be lightly brushed with a detergent mixture and rinsed clean.
- To finish off, paths around your home are rinsed clean from the dirt and grime that has been washed from your home throughout the cleaning process.
2. Hand Wash
(This method is acceptable providing high pressure is not used to wash off.)
This method is similar to low pressure water saving external home wash but may not include the water saving equipment and most of the time the window are not included.
3. High Pressure Wash (Not Recommended)
This method is not recommended. The pressure produced from this equipment is best suited to cleaning Driveways and Paths (up to 5000psi).
The pressure developed by this machine, even when the pressure is turned down, makes it impossible to control around door and windows without running the risk of water pouring in through small gaps.
High pressure will not remove built up grime and mildew. This can only be removed by brushing and treating. There are no advantages to use high pressure to externally wash homes, but there are many disadvantages. The reason that some companies use high pressure to clean homes is more than likely that they don’t want to have the expense of purchasing a Water Saving Low Pressure Unit, preferring instead to use the one unit for both house washing and driveway cleaning. While this makes economic sense for the company, your home may suffer the consequences.
4. Low or high Pressure hose on hose off Wash (Not Recommended)
This method is a poor way of cleaning that involves spraying high concentrations of chemicals and detergents on your home, left to stand for a few minutes and washed off with either high pressure or low pressure equipment. There is no brushing at all and no window cleaning. This method is generally very cheap in services and cost and as the old saying goes “You get what you pay for”.
This method does remove the mould but the underlining dirt and grime build-up remains. This can only be removed by brushing all areas with a soft broom and a mild detergent then rinsing with clean water.
You have to ask yourself, is the saving a little money worth the risk of potential damage to your paintwork? The few dollars saved could easily end up costing you thousands.
