Buying Guide: Factors to Consider Before Purchasing Biodegradable Car Wash Soap
As individuals become increasingly conscious of their impact on the environment, many are switching to biodegradable car wash soaps.
If you’re considering making the switch yourself, it’s important to know what to look for in a quality, eco-friendly product.
These features you should consider before purchasing a biodegradable car wash soap include:
1. Balanced pH
A balanced pH is the first thing that a biodegradable car wash soap has to have. pH is a measure of whether a substance is acidic or basic. A biodegradable car wash soap should have a pH level of 7, which means that it is neutral.
This pH level makes the soap safe to use on any car surface, including windows and vinyl surfaces.
After washing and rinsing the car, the soap leaves behind a neutral surface, so it will not strip the wax or damage the clear coat of the paintwork.
2. Heavy Foaming-Formula
Foam is a crucial component that every biodegradable car wash soap should contain. When foam is formed, it weakens the dirt, grease, and grime that tend to build up on the car’s surface when you leave it dirty for a long time.
When this happens, it becomes much easier for you to wash the car quickly and remove the dirt effectively. The foam that is formed will also provide additional lubrication so you don’t scratch the clear coat of the paint or strip the wax.
3. Concentration
Most biodegradable car wash soaps available on the market today are more concentrated than their non-biodegradable counterparts. But some are more concentrated than others.
A highly concentrated biodegradable car wash soap will have a minimum soap-to-water ratio. This means you will use a small volume for each wash.
When this happens, the bottle will last for a long time, even if you wash your car frequently, which means you’ll be able to save money.
4. Lubricity
When buying a biodegradable car wash soap, consider its lubricity or slipperiness. The more slippery it is, the better. Lubricity will minimize the friction between the surface of the car and the cleaning cloth or sponge that you are using to wash it with.
When the friction is alleviated, you will be able to effectively wash the car without harming the clear coat or damaging the wax. With more lubricity, you will also be able to expend minimal effort to wash the car.
5. Water Spot and Streak Resistant
The best biodegradable car wash soap will keep your car clean and the paint coat shiny.
Besides that, the soap will clean the car effectively and leave behind a surface that is free of streaks, water spots, and swirl marks. Swirl marks are detrimental to a vehicle’s top coat and paint job, so the fewer, the better.
A car that is free of water spots and streaks will keep the wax looking shiny for a more extended period.
6. Scent
If you are allergic to certain odors, consider using a biodegradable car wash soap with a scent-free or subtle scent. This way, you can avoid an allergic reaction when washing your car.
The biodegradable car wash soaps that are available on the market are formulated from different chemicals. As such, the smell/scent of one soap is different from that of another. You will even find that some of these car wash soaps come with fragrances.
Benefits of Washing Your Car Using Biodegradable Car Wash Soap
When washing your car, opting to use biodegradable or environmentally friendly car wash soap instead of conventional soaps can result in fewer pollutants entering our groundwater and waterways. Let’s explore some of the key benefits of using these safer cleaning products!
1. Conserves Water
Using biodegradable car wash soap to wash your car helps conserve water. These soaps have ingredients that help them form foam easily.
Additionally, the foam is very easy to rinse, so you get to use less water when washing and rinsing the car compared to when you use the non-biodegradable soap.
2. Safe on the Paint
Biodegradable car wash soaps are pH-balanced. This means that they are neither acidic nor basic. Washing the car with this type of soap won’t harm the clear coat or paint. Besides, it will leave behind a neutral surface.
3. More Effective
Most biodegradable car wash soaps are formulated to be more effective than their non-biodegradable counterparts. They will remove even the most stubborn dirt easily.
Furthermore, the soap will penetrate the hard-to-reach crevices of the car and remove the hidden dirt.
4. Enhances the Car’s Paintwork
A biodegradable car wash soap will not just clean the dirt in your car, but also enhance the paintwork.
Most biodegradable car wash soaps are formulated with all-natural ingredients that enhance the shine of the clear coat, giving it a glossy finish similar to a waxed car.
5. Safe for the Environment
All biodegradable car wash soaps are made with natural compounds that degrade overtime before that get absorbed by living organisms.
As an eco-conscious individual, you will not harm the environment, regardless of how often you clean your car. Besides, the soaps are safe for your health as well.
6. Safe on all Vehicle Surfaces
Since biodegradable car wash soaps are made of natural ingredients, they are safe to use on all surfaces of your vehicle.
This includes rubber, plastic, paint, window, and vinyl surfaces. You are also assured that they won’t harm the clear coat of the paint or strip the wax.
Final Words
After exploring the numerous characteristics of the best biodegradable and environmentally friendly car wash soaps available on the market today, it becomes clear that these soaps are a great option for any vehicle owner seeking to remain environmentally conscious while washing their car.
Not only do biodegradable soaps offer superior cleaning power, but they also ensure that no toxic substances are released into our fragile environment. In addition, many companies producing these soaps have consistently demonstrated that environmental protection is their top priority.
Whether you’re looking for an easy-to-use standard car wash solution or something a bit more specialized, there’s bound to be an eco-friendly solution that fits the bill.
Ultimately, by choosing to use biodegradable or environmentally friendly soaps for your car washing needs, you can rest assured that your vehicle will look great, and Mother Nature will thank you, too!
