To clean the grease and stains off your plates, cutlery, and kitchenware, you use dish soap. It’s designed to attack the dirt so you have clean dishes.
That’s the same reason why people want to use dish soap in their pressure washers. It removes grime from the different surfaces around your house.
However, it isn’t a case of one soap being used for all cleaning jobs. The surface you want to clean determines which product you need.

In the last section, we showed you how to create your specific soap. Yet, the processes may seem a little overwhelming.
How do you use nothing but dish soap with your pressure washer? Follow these steps:
- Get a dish soap that has degreasing properties.
- Add ⅓ cup of soap to a gallon of water.
- Check that the soap and water are thoroughly mixed.
- If it’s too sudsy, add more water to dilute the soap even more.
- Use a 65° nozzle to apply the soap. This tip is specifically made for soap and has the lowest level of water pressure. You could opt for a 40° tip if you want.
- Spray the soap over the area you want to clean. Let it rest for a while to break down the dirt and stains.
- Use your 40° or 25° tip to rinse away the soap. The 25° tip has a higher pressure, so make sure you use caution when cleaning with this nozzle.
Remember the key to using dish soap with your pressure washer is to minimize the suds. Too much foam and you are going to find your washer clogging up.
Also, as we mentioned the different surfaces need specific cleaning formulas. You may find your cleaning attempt with just using dish soap disappointing.
You may be tempted to use dish soap with your washer, but there are some warnings to bear in mind.
Hot water is the ideal type to use in pressure washers with dish soap. This is because hot water heats the soap and makes it more effective at dissolving and lifting grime.
If your pressure washer can’t utilize hot water, then using dish soap isn’t worth the effort. The cold soap may seem to work to some degree, but you could be frustrated by the final result.
You may find that the dish soap has too many suds when it’s being sprayed out. If that’s the case, then you need to do a long and thorough rinse job.
That sees you having to use more water than anticipated. Also, the overall job ends up taking more time than you expected.
Pressure washers are a powerful way of cleaning. Using dish soap may give you a good result, but such detergent isn’t designed for washers.
If you have used specially formulated pressure washer detergent, you will notice the difference in the quality of the wash. Such soap may cost you more to buy, but you are going to get the results you want.
As we just mentioned, the cost of pressure washer detergent may have you thinking of a cheaper alternative. Dish soap can be seen as an attractive option as it saves you money.
Dish soap can leave an unsightly film on the surface. That will have you wishing you used some other product to clean with. Now you are contemplating having to clean the area once more.
Though you can use soap with your washer, you have to keep away from bubbles, suds and foam. These all can block the tubing, hoses, and other components of your washer.
That cleaning job now has to be put on hold as you deal with the clog. A worst-case scenario is that you have to get your machine repaired.
For electric washers, that isn’t a cheap option.
Gas washers are hardier, but they can still be affected by using the wrong type of soap.
Have a good read of the manufacturer’s manual that came with your washer. Are there soaps that they specifically recommend? Of course, this could be seen as some type of sales pitch. Such may be the case if the brand of the soap is associated with the washer’s manufacturer.
Carefully study the warranty card and see what the terms and conditions are. Is there an allowance made for the use of dish soap? If not, then don’t be surprised when your warranty claim is turned down.
If in doubt about using dish soap, then err on the side of caution. Stick with your manufacturer’s soap and detergent recommendations.
