Liquid vs Powder Detergent

If you want a better cleaning performance or you want to decontaminate the area you are cleaning, then pressure washer detergent is what you need.

When buying the detergent, you can opt for the concentrated liquid detergent which comes packed in liquid bottles. You can also opt for the powder detergent which should be mixed with water before use.

Normally, the detergents come with instructions on how to dilute them into proper proportions. If you get the dilution proportions wrong, you will not get an efficient clean if the detergent used was too little.

On the other hand, if the detergent exceeds the recommended amount, the solution becomes too thick and you risk damaging the washer’s pump.

When it comes to application, the detergents can be applied manually to the surface or be added to the washer for spraying the surface that needs cleaning.

If you are applying the detergent manually, first wet the surface you’re cleaning then spread the detergent to cover every inch of the surface. When every inch is covered, turn on your washer and spray the surface with clean water.

Most pressure washer manufacturers recommend the liquid detergent as it is easier to use and is more eco-friendly. Also, most professional cleaners use the liquid detergent.

If you’re thinking of buying powder detergent for your pressure washer, make sure you get a brand that is friendly to your washer and learn the dilution proportions.

Where to apply

Pressure washer detergents are tough on stains, grime, mold and other forms of dirt but are gentle on surfaces.

As long as you have the correct attachment for your pressure washer, you can apply the detergent to any surface you wish.

So whether you are cleaning your car, your brick walls and floors, concrete walls, garage doors, steel surfaces, windows, driveways, sidewalks, etc. You can use pressure washer detergent for thorough cleaning.

Final Words

Unless you have an industrial pressure washer, avoid using hot water to achieve the perfect cleaning performance. Industrial pressure washers have pumps that are built to withstand boiling-temperature water while other types of pressure washers will probably get damaged by the intense heat.

However, you need not worry because pressure washer soap is just as effective at removing grime and dirt from pressure washers. Liquid detergents are the best but you can also opt for powder detergents for your pressure washer. Lastly, the Simple Green 11001 is our best pick as we believe it to be the best all-purpose pressure washer detergent.
