Pressure Washer Detergent Buying Guide
It would be best to look out for a few things when shopping for the correct pressure water detergent. Keep in mind that just like tools, these items differ in quality and results. Here are a few things that should be on your checklist:
Intended usage/ purpose
It would be best if you considered the job at hand before settling on a pressure water detergent. You should factor in what you would like to clean, the surfaces you want to work on, and whether you need the detergent for professional or general home cleaning.
From our reviews, you can establish that some detergents are best suited for cleaning sidewalks and driveways, whereas others work best when used on sidings. Also, some detergents are meant for cars only.
However, we highly advise you to settle on a multipurpose detergent to be on the safe side. Such options will save you money and time since they are suited for all types of cleaning.
Effects on the environment
It would be best if you weighed the impact that your option will have on the environment. We highly advise that you settle on a safe, biodegradable detergent. Remember that there are vegetation and animals around the areas that you will be cleaning.
All the recommendations in our reviews are safe, biodegradable detergents formulated with environmental-friendly ingredients. You should also avoid detergents that use bleach to clean surfaces. Ensure that you thoroughly scrutinize all the ingredients used in the formulation of the detergent. Look out for any toxic element that may harm the environment.
Type of detergent
This is perhaps one of the first questions you should ask yourself before buying a pressure water detergent. Several detergents are suited for different roles. Some cause very little foam, which may not go well with your cleaning purpose.
On the other hand, other detergents produce excess foam and can be used with a foam cannon. These are the best options for washing your deck or driveways but not foam your car. Therefore, make sure that you settle on a detergent that aligns with your purpose.
Detergent or soap?
Pressure washer detergent tends to be a more potent mix than just soap. It is also concentrated and lasts longer, and is rinsed more efficiently. Soap may leave residue, streaks, and smudges requiring additional cleaning by hand, and that’s not good news! To make your own DIY pressure washer detergent, you can start by mixing 1 gallon of water with ⅓ cup laundry detergent powder and ½ a pint household cleaner. If desired for general purpose cleaning, use vinegar also in the recipe to get rid of any odors that may be present on the surface being cleaned or if there is excessive dirt build-up around it.
Hard or soft water?
Another consideration is the type of water you have where you will be using the pressure washer. Harder water will wash quicker, but it does tend to leave streaks and smudges. Look for a detergent that is more suited to the water type you have.
Brand
The choice of brand is usually a huge consideration, especially for first-time buyers. Certain brands have managed to beat all odds and remain at the top. Others are also known worldwide for their premium products.
We would highly advise you to get a good brand and be loyal to it to prevent disappointments. We also understand that some people love brand hunting and shifting. However, ensure that you are careful while trying out different brands. If you are a first-time buyer, I would advise you to settle on any of the brands we have reviewed.
Customer reviews and feedback
The best way to know about a product is through listening to what customers and users have to say about it. Feedback is necessary since it depicts the product’s accurate information, away from what the manufacturer may have provided.
Therefore, before settling on a product, take some time, and look up what consumers have to say about it. Products with good customer reviews rarely disappoint, offering you value for your money. Also, take some time and look at the ratings of the detergent that you are eyeing. A good rating means that the product can live up to the standards that you want.
Know your pressure washer
Each pressure washer has different features, and knowing what your has will help you decide which detergent or soap to use. For example, Chemical Injection and Detergent Injection are phrases pressure washers manufacturers use to advise whether the model has a tank for chemical cleaners or detergents.
Look for other phrases, too, such as Unloaders or Thermal Relief. This reduces the heat buildup and pressure in the washer and will significantly increase the lifespan of the pressure washer.
It’s super important to know the max pressure your washer works at as this guides you whether you will be able to use a multi-purpose detergent on your vehicle or whether the pressure is so high it will cause damage.
Your environment
Consider your environment, too. If you live in an area where sand dust is prevalent, a more light-duty pressure washer of around 1300 to 1900 PSI and 2 GPM will suffice. You don’t need to buy a more expensive model. These lightweight models are perfect for cleaning garden furniture, cars, boats, decking, and patios.
A medium-duty pressure washer rated at around 2000 to 2800 PSI and 3 GPM is ideal for areas that suffer high pollen counts. Mildew, mold, algae, and grime all build up over time, and the slightly more powerful pressure washer will be ideal for keeping your residence looking great.
Nozzle
Most pressure washers come with a variety of nozzles, which impact the soap or detergent you choose. Here are the different types of nozzles and their uses:
0° – has the most power and highest concentration
15° – is ideal for heavy-duty cleaning
25° – perfect for general maintenance around the home
40° – less pressure makes it suitable for cleaning surfaces susceptible to damage, such as paintwork.
65° – lowest pressure making is perfect for soap and other cleaning agents.
Other considerations include the availability and type of scent or lack thereof. All in all, make sure that you settle on a detergent that will help you achieve what you want.
Conclusion
Best Overall pressure washer detergent went to the Oxy Solve Total Outdoor Pressure Washer Cleaner as it’s environmentally friendly, with no bleach, and multi-purpose. Our Best Value award went to the Karcher Multi-Purpose Cleaning. Although a branded make, it is good with any make and model of pressure washer so long as you follow the manufacturer’s advice and guidelines.
