Pressure washers are designed to clean many different dirty surfaces, remove rust and strip paint. They work by applying highly pressurised water through a specially designed nozzle.
The strength and ability to clean different types of stains, dirt and other blemishes depends upon the machine’s rating in pounds per square inch (PSI) and the gallons per minute (GPM) of water flow.
There are many different models of pressure washers from which to choose. To help you decide which particular machine is best suited for your needs, there are certain things you should know.
Following are the top 10 things to remember when buying a pressure washer.
1. Pounds per Square Inch (PSI)
Any home (aff) improvement project requires a certain amount of pressure to disturb the dirty surfaces. The higher the PSI, the greater the cleaning power. For most do it yourself (DIY) projects, a machine with a rating of 1,500 PSI to 2 (aff),000 PSI is quite adequate.
2 (aff). Water Flow
While the PSI dislodges the dirt, the flow of the water washes the dirty residue away. The greater the gallons per minute of water flow, the more dirt and residue can be removed and the faster the job can be completed.
3 (aff). Type
You can purchase a machine that is powered by gas or electricity. Generally speaking, more powerful units are powered by the fossil fuel, while less powerful units rely on electricity.
Given two distinct washers that have similar performance features, you should consider purchasing the one that is designed with superior parts. Quality engineering and more durable parts and components will perform better and last longer.
Type, quality and performance will all contribute to the price you pay for your machine. Buy something that can do all of your anticipated cleaning jobs and will also stay within your budget.
6. Home (aff) Improvement Projects
Most projects involve cleaning a concrete slab, stone patio or garden pathway. You can also use this handy machine to wash your vehicle, clean the exterior of your house or even remove the grime from your barbeque grill.
7. Adjusting the Pressure
One of the mistakes a DIY home owner can make is applying too much pressure to a painted surface. Be careful not to remove the paint along with the dirt. Dial down the pressure if you are not sure how much power you need.
8. Nozzle Adjustment
A narrower spray angle will provide a more powerful cleaning force. At zero degrees, you can remove stubborn dirt, while a 15 degree angle will be suitable for jobs like removing paint or other finishes. For delicate jobs, chose a 40 degree wide fan pattern.
9. High Pressure Hose
Your machine will come with a high pressure hose. It performs best when you keep it uncurled and make sure there are no kinks in the line. Always check your high pressure hose connectors to make sure that they are tight and no water is leaking.
10. Basic Maintenance
Prolonging the life of your machine and keeping it in good working order requires a little maintenance. Wash off sandy dirt and grit from the exterior, clean any filters and store your machine in a dry, protected area.
