Most pressure washers start at 1300 PSI and can be adjusted above if necessary. Garden hoses produce 40-70 PSI 

It is impossible to reach more than 200 psi, no matter what you do, the attachments you use, or the air compressor. This can double the job it does. This is useful when it needs a little more power than it provides. However, it cannot fully fulfill the needs of a pressure washer.

Can Garden Hose Become a Pressure washer?

Length: The length of the garden hose depends on your requirements. Would you prefer the shorter or, the longer? Consider your needs when making a decision.

Temperature: Considering the temperature is critical, as it can either make or break the hose. An improper temperature can wreck the house.

Nozzles: You should consider nozzles when selecting a garden hose. It requires a proper nozzle to function.

Pressure: Since not all garden hoses can withstand high pressures, pressure is the most significant factor to consider. You should make sure your garden hose can withstand the pressure.

To clean it, you can use soap or wash it with dishwashing liquid with hot water. For oil stains, you can use warm water and soap and then remove them by yourself. 

2. You Can Clean Using Plenty of Water

Soft washing can be the preferred washing method. You should be aware that it uses a lot of water and does the job like a pressure washer. Using this method, you can clean places that a pressure washer cannot reach because of the pressure of the water. 

By using soap and a soft washing method, you can remove the stains. In this method, you can wash with any soap. You can even use the regular garden hose for this job since it has some low-pressure. 

3. Use Warm or Hot Water to Enhance Cleaning Efficiency

The temperature of the water plays an imperative role in cleaning. Whether you are using the old method or the pressure washer, the use of warm water is always a helpful thing. It is easier to remove stains with hot or warm water.

By liquifying any dirt or grease present, hot water can increase the chances of removing them without much effort and give those surfaces a fresh look.

Yet, one-time spending can save you a lot of effort in the long run. 

What’s the Right Pressure for a Home Pressure Washer?

Pressure washers usually have a range of 1300-2400 psi in everyday use, which is the best range for household use. For heavy-duty projects, going above the range is okay if you need more pressure. 

However, the average pressure for houses is 1500 psi. It is exceptionally crucial for your safety that the water coming out of your hose can be blocked by an object. If it cannot penetrate through one, then there’s no point in using the tool.

You may have to hire someone to do the job if you are concerned about safety. Otherwise, you can do it yourself. Depending on your needs or capacity, you can purchase an eclectic pressure washer or a gas pressure washer.
