Why you should be cleaning your car on your own?

Car washing shops are likely than not to use more affordable but lower quality soaps that may wear the color of your car over time. They focus only on speed and cost. If you clean your car you save a lot of money you would have otherwise given to a car wash. Since it’s your car you are going to be extra careful and pay minute attention to having spotless detail.

This soap is quite thick. If you run it through your fingers you can feel its slime consistency. It’s this thickness that allows for that nice super preserving perfect shinny wax ‘look ‘and texture.

Unlike the older generation hazardous soaps that needed you to buy waxing products, Mother is an all-in-one car washing soap that cleans or removes grime and dirt and also shines and protects your car with a stunning wax finish.

To get the best results you should be using Mothers regularly to maintain and boost your existing shine. It won’t work very well if you sporadically use it and let your car paint stay with road grime and dirt for extended periods. When grime and dirt are allowed to firmly stick and interact with your car paint it can be difficult to remove it. And restoring a perfect wax is almost impossible in such careless cases. Otherwise, used regularly this brand will remove and liquefy stubborn grime and dirt on your car surface.

There is an urgent need to switch to environmentally friendly right away. Whatever products you use should not be harmful to the environment. Mother’s wash and wax is totally biodegraded and will be broken down more substrates that microbes can actually extract energy from.

This car wash soap is also pH Balanced. This means that it has a neutral pH is 7 and won’t leave the surface either basic or acidic. Acidic or basic cheap washing chemical strips the surface of your car leaving it very reactive to dirt and grime so be very careful never to use such products on your car.

Whether used in a bucket or soap cannon it produces excellent suds. Its super sudsy foam washes away and suspends any stubborn dirt and road grime attached to your paint.

It produces stunning results for all color types if you do not let grime adhere to the surface for extended times. We have used it on difficult to maintain red and black car paint. Its heavy super forming formula can clean, protect, and wax to shine any color you want.

Although it can work with a bucket, we advise against using buckets due to increase water loss. A soap cannon and pressure washer significantly reduce the amount of water used. A water crisis is imminent and we need to converse this precious resource. It works very well with a soap cannon and forms super suds that will wash away dirt. The lubricating form leaves a smooth surface free of any scratches or swirl marks.

We were very impressed with the performance of this product and we can really appreciate the users in the review sections on amazon that have highly rated this product. This is definitely one of the best car soaps on the market.

Although not necessary we can use it with your favorite polish as this soap can work with any polish as long as you regularly wash and wax it.

Remember that this soap needs rinsing and you need to have access to water to get a smooth clean finish. And you should immediately rinse after your suds have run their course. If you let the soap dry before your rinse or if you do a poor rinsing job then your car will have wax residues and won’t have the perfect finish. If you notice that you did not rinse properly and some dry soap wax appears on the surface you need to rewash otherwise your wax won have a glossy stunning look.

If your car needs a flat non-glossy finish then before you wash your whole car with this soap try it on a small test area and see if it changes your flat look. For specialty finish paints you need to always run a small test pain actually. In most such cases this soap can work. But we recommend washing only soaps without wax in general for cars that require a flat finish.

Mothers wash and wax is not only good for the body but also does an excellent job when washing and cleaning your rims and wheels and inside the wheel. You need to use a separate microfiber cleaning cloth so that you don’t transfer the dirt to your car body as the wheels normally have tough road grime.

What to Consider when Buying the Best Car Wash Soap for Pressure Washers

pH balanced

pH measures the acidity and alkalinity of solutions. A neutral pH is 7. When it comes to soap ad shampoos for cars it’s very important not to use the ones that are not pH balanced. Acidic or basic solvents strip away your wax and may damage your paintwork. They also leave the car relatively charged and this can attract more dirt to stick to the surface. Make sure you are using a pH balanced soap that will protect your car.

Super suds

The other important factor to look at when buying car soap is its foaming ability, what we call suds.

Foam capacity is very essential to the cleaning process and is responsible for actually dissolving away the stubborn dirt. This is your hands-free scrub and the technology behind car cleaning. The more suds you have the better you’re cleaning results. In general, using a cannon or foam gun will always give you more suds than just using a simple bucket.

Biodegradable

The 21st century will be dominated by a move towards sustainability and environmental protection. We all are reconsidering how we can be more careful in preventing ecological disasters. Car washing is a routine task that produces copious amounts of waste solvents. To prevent a buildup of toxic solvent we need to push for the use of biodegradable products that actually end up in the food chain of microbes providing energy.

Brand

Obviously, you should only risk your hand earned car with soaps from the most trusted brands. There are lots of cheap brands out there and you are going to cry if you want to play it cheap. Our articles will guide you on what we tested ourselves on our own vehicles so that you are spared the trouble.

Price vs. quantity

You do not want a soap that is not value for the quantity. You need to wash your car weekly and you don’t want to break your bank just keeping that perfect wax. You need to get a soap that is both affordable and comes in good volume for multiple washes and waxes.

Specialty finishing

Please pay close attention to the paint finish of your car and color as well. Some finishes are non-glossy and can be altered by waxes. Carefully read your soap properties to see if it works for both gloss and non-gloss finishes.

FAQs

1. Why you should not use a conventional bucket but purchase a soap cannon and pressure washer?

Water is a very precious resource and we all need to make sure we don’t waste it.

2. I have a specialty finish or flat finish how can I be sure this soap won’t spoil it?

I always encourage that you test your new soap on a very small spot of your car and see if it performs well. Only if you are satisfied should you then wash your all car body. A Very small patch will do on the part not too prominent.
