Things to consider when buying the best car wash shampoo for pressure washers
Suds help in removing dirt and other contaminants from your car’s surface. Therefore, the more bubbles/ suds the cleanser produces, the less effort will be needed to scrape the car to eliminate the dirt.
In addition, a car wash shampoo that produces more bubbles will help you wash the car quickly without leaving a mark. So, make sure you look for a car wash soap that produces high-quality, thick suds when blasted at high pressures.
The water pH is a regulating component that protects the car’s paintwork. For that, it’s important to look for a car wash soap with a neutral pH formula to avoid damaging the car paint.
For instance, if the formula has a high pH level, it will be more acidic, thus damaging the car’s clear coat.
Pressure washer car soaps contain chemicals in their formula, which is why they smell in the first place. Therefore, the smell is another important factor you need to consider when looking for the best car wash shampoo for pressure washers, especially if you’re sensitive to smell.
Or else you’ll end up sneezing or experience worse problems if you choose a product with a strong smell.
Generally, you should look for a car wash shampoo that is scented with natural ingredients. More importantly, it should have a mild scent that pleases your senses.
Pet & Environment friendly
If you’ve got a pet, chances are that it will be loitering around as you wash your car. Unfortunately, pets’ curiosity level is always on the rise, which is why they love licking everything. For that reason, it’s important to buy a non-toxic pet-friendly car wash shampoo that doesn’t pose any danger to your pet.
Similarly, the formula should be biodegradable and eco-friendly to protect the environment. Or else it will end up damaging your beautiful lawn and the pants around when soapy water flows down your driveway.
In addition, this water can go down the drain and affect aquatic life if the car wash soap formula contains toxic ingredients.
Pressure washing your car with the best car wash shampoo will help you save both time and water. Unfortunately, not every car wash soap out there is suitable for use with pressure washers as some products may clog the machine’s nozzle.
Luckily, I’ve listed some incredible cleaners that are specifically designed for pressure washers to help you find the perfect option for you in no time!
