Can You Use These Cleaning Liquids in a Pressure Washer?

As you know, pressure washing uses a high-pressure water spray to remove loose paint, mud, dust or any type of dirt from a surface or an object, like buildings or vehicles. Its volume is in gallons, often in the pump. The pressure, on the other hand, is known to be measured in pounds per square inch. However, given what we know about its measurements, there are still some questions as to what we can use in one. 

Can you use ammonia in a pressure washer? Yes, you can. But more importantly, know your ratios and the general effect of what you are putting in the pressure washer. It really depends on what it is and the type of effects it can give in the pressure washer to wash off the stations. You will be surprised as to what you can and cannot put. 

In this article, I will make it easier for you to understand if it is safe to put certain liquids in the pressure washer and the type of ratios it requires for safe and efficient use. 

Using Ammonia in a Pressure Washer

An ammonia mixture is one of the easiest ones to make when you are putting it in a pressure washer. However, we have to be careful with the ratios that we are using for it. Mix about ½ cup of ammonia in 1 gallon of water. Then, add a pint of rubbing alcohol. 

Given that mixture, this should be a fast-drying formula that would work very well with windows. windows without a squeegee. Further, the ammonia formula works best if the windows you are trying to clean are not that dirty and beyond hand reach. 

Ammonia is a common glass cleaner and stainless-steel cleaner, so it works best on those surfaces. 

Using Chlorine in a Pressure Washer

Unlike ammonia, chlorine is used primarily for swimming pools. Like bleach, it has the Sodium Hypochlorite characteristic. Chlorine in groceries are ready for use and comes at a concentration of about 10%. However, the highest concentration of them can be found from chemical suppliers at 12.5%. 

Liquid chlorine can be put into a pressure washer, and because it is already in solution, it produces acid the moment it touches water to clean it out. This is mostly used in large commercial pools rather than in small ones. 

Using Carpet Cleaner in a Pressure Washer

For a lot of us, rugs are very special in our personal decor. They warm up the room and provide great space for kids or pets to run on or rest on. However, due to this same reason, it often gets dirty. 

As a preventative measure prior to using carpet cleaner in a pressure washer, you have to give them a regular and constant cleaning. For this, you would need dishwashing fluid at about ⅓ of a teaspoon, a brush, drying equipment, the pressure washer, and laundry detergent

First, place the rug in a concrete sidewalk since you will be needing a lot of space for it. It might be troublesome to activate the washer indoors. Lay the rug upside down to first attack the bottom of the rug. Before washing, sweep it on both sides and prepare for a thorough cleaning. Remove initial debris, hair, or any food that the pressure washer will treat as a barrier to its efficiency. 

The next step is to use detergent. First, see the instructions on the back of it for guidance. Most people just go into it blindly and mess up their rugs. By reading the directions, you can avoid this issue altogether. Attend to the machine and check if it is well oiled and has the necessary attachments. Regardless if it’s electric or oil, make sure that it is well powered and that the nozzles are sturdy enough to handle the job. 

The final steps are to basically rinse thoroughly through it, removing all the soap after washing it gently with some detergent. Dry the rug against the sunlight and wait till it is good to use. 

The most key tips are to use the right cleaning solution, pressure and maintain the right distance. Do not point the nozzle too close and do not use hot water. 

Using Fabuloso in a Pressure Washer

Is it safe to use Fabuloso in a pressure washer? The idea of combining the cleaning power of Fabuloso with the efficiency of a pressure washer is tempting, but there are factors to consider.

While Fabuloso is a popular multi-purpose cleaner, it’s essential to check the manufacturer’s guidelines of your pressure washer before using it. Combining Fabuloso with a pressure washer might not be recommended due to potential damage to the machine or reduced cleaning efficiency. Always prioritize safety and equipment care. 

Using Wet & Forget in a Pressure Washer

Wet and Forget is recommended to be used in a pump-up garden sprayer, backpack sprayer, as well as a low-pressure agricultural sprayer. However, if the surface is of high elevation, or large in general, use the Wet and Forget Hose End product with a pressure washer. 

When using a pressure washer, only use those that can pull from a separate container with a 5:1 premixed ratio solution. If the ratio is anything other than a 5:1, do not use a pressure washer. The reason being is that it will not get you the proper dilution results that you want to achieve.  

Using Jomax in a Pressure Washer

Jomax can most definitely be used in a pressure washer. It removes mold and mildew that is stubborn on exterior stains. It is a bleach-free formula that is intended to be used by a pressure washer or by manual usage. Further, it is suitable for siding, concrete driveways, sidewalks, brick, and stucco

Before using it, test the pressure washer on an inconspicuous area to make sure that it works on that specific surface. Do not mix it with any other chemicals and make sure to not use stained or painted surfaces. Instead, water pressure can be used to remove paint or any discoloration. 

Before use, rinse any type of surrounding vegetation with water. Severe stains, of course, would take more than one rinse. To be sure and safe, use the instructions of the manufacturer. 

After the rinse, insert the pressure washer siphon into a concrete option. If using a reservoir machine, pour the concentrate into the pressure washer. In small sections, apply the concentrate to the surface with low-pressure sprays. If the surface is vertical, apply it from the top-down. When you start doing this, do so for around 5 minutes to allow the concentrate to really work through.

Then, remove the siphon tube from the container. Finally, rinse the surface with the high-pressure spray and rinse the parts prior to storing it away. 

If you are using it manually, there will be a different process, but it has the same idea. Dilute 12 ounces of concentrate with 1-gallon of water. Dab it on the small sections and apply the pressure washer. After all that is done, rinse the parts.

Like the Jomax, it is important to rinse any of the nearby plants with clean water and test the area first. Any type of overspray can be neutralized with large volumes of water. On an extremely soiled surface, it is definitely worth it to use a scrub with a bristle brush and a second application could be needed. In some cases, mildew may never be removed from porous surfaces. 

If there is a case of severe oil or grease stains, oil may bleed into the surface or leave a stain. Repeated rinses could lighten the stains, and slightly increase its aesthetic value, but it cannot be removed completely. Most importantly, do not mix it with any other chemicals. 

The product application should also be mixed 1:10(12 oz of concentrate with 1 gallon of water), one bottle of concentrate will make 11 gallons worth of premix, and clean around 3000 sq ft. This can be done with a pressure washer, pump up sprayer, or brush. 

With a pressure washer, rinse the surrounding plants before and after you use it. Wet the surface that you plan to clean and place the detergent in the sophon tube. Open the enter value for max flow.
