A buyer’s guide for car cleaning soap

If you love your car, you definitely not only want it to end up clean when you wash it, but shiny and radiant as well. If it was just about cleaning, then you could have simply splashed water and let it dry.

With that being the case, you should go for a cleaner that will be tough on dirt but handle your car like a baby. It should also be gentle on you, your pocket and Mother Nature.

So what do you look out for?

1. Ingredients

Some of the most important factors to consider when it comes to car wash ingredients are;

(i) Foaming

The ingredients should erupt into a long-lasting foam once mixed with water to the recommended dilution. This will enable the suds to grab and suspend dirt and grime from the vehicle surface and crevices, without the need of you scrubbing it off. Incessant scrubbing would scratch the paint and glass.

 (ii) pH balance

An acidic car shampoo or soap will gradually corrode the wax, clear coat, rubber seals and all, leaving your car looking old just because you wash it.

On the other hand, a pH neutral cleanser will neutralize the environmental pollutants and won’t eat away your car finish. Besides, it won’t leave your hands dry and scaly.

(iii) Biodegradable ingredients

You borrow the world from your kids and the best interest you can pay is to use compounds that decompose and disintegrate as soon as they hit the ground.

Plant oils such as citrus have proved to be as effective as synthetic polymers and yet they won’t take centuries to disintegrate.

2. Product concentration and cost

The more concentrated the soap formula is, the less you will use per cleaning session and if the price is comparable to other washes, then it is better for your pocket since it will last longer.

3. Waterless vs rinse based car wash

There are car cleaners that are made of rich surfactants and polymers such that you only need to wipe your car with a wet cloth and they’ll grab the dirt and grime. This conserves water and you don’t have to end up with a swampy driveway. However, they are most effective for light touch-ups and they are not good at washing off mud, heavy grime and grease. For the heavy dirt, you may need to pressure wash and then rinse.

4. Customer reviews

A marketer cannot speak ill of his product and therefore it is important to go through the end user reviews on Amazon and learn about their experience. It is also important to check the statistics- total number of reviews and the average score. A high number of positive reviews are definitely an indicator that you are missing out.

How to use a car wash soap

One of the ironies of our modern times is that ignorant cleaning of your car may actually damage the car material and finish. If you use the wrong cleanser or the wrong method, then you may end up with a jalopy of a car with ugly swirl marks, spots, eroded wax, and sealants.

But once you are armed with the right information, you can wash your car with the confidence that what you are doing will keep it radiant for the long haul.

Necessary items for washing your car 

You might be wondering what can i wash my car with? Just like any other cleaning process, there are some items that you can’t do without when you want to clean your car exterior.

Let’s see the items;

Paint and wheel soaps

The best soap to wash your car paint should be gentle both in pH and beading of ingredients in order not to grind the wax and paint. However, you will need a tougher wash that will clear grease, tar and road grime from the wheel and tires.

Pressure washer or foam gun

If you prefer a faster wash and rinse method, or the car is extremely muddy, then you need to get a pressure washer or a foam gun.

A foam gun is fitted with foam cannon and works with your typical garden hose as long as they can fit.

A pressure washer can pump a thicker spray that will stay on your car for longer compared to the thin foam gun spray.

Wheel brush

The wheels bear the highest dirt, grease and mud and there is no need of hurting your hand struggling to clean all that from the spokes with a sponge or towel. What you need is a car wheel brush to scrub the spokes, inside the fender and the tire treads.

If you are not using a waterless car wash soap, then you will need water from a garden hose for rinsing. The hose should have a spray nozzle to adjust the pressure and also conserve water.

Best way to wash a car without scratching

Step 1; Make sure that your car is cool and in a shade if it’s sunny. If you were driving, let the car to cool down since the hot surface will evaporate the soap faster than you wipe it, leaving swirls and spots.

Step 2; Gently rinse the car from the garden hose to remove loose dirt and mud. It also soaks the tough dirt and grime so that it is easily lifted by the cleaner without scratching the paint.

Step 3; Pour the wash concentrate into one bucket or foam cannon, and dilute with water to the recommended ratio. Fill the second bucket with clean water.

Step 4; Wet the sponge, terry cloth or mitt in the soapy solution and start by cleaning the car from top to bottom. The lower parts are always dirtier and it’s, therefore, better to let the dirt run downwards. As you clean, use straight hand strokes and not circular motions. Circular patterns can create unwelcome water swirls. If using a pressure washer, adjust it to low pressure since a strong jet can rip the paint.

Step 5; After you have a washed a section with the soapy water, rinse the mitt or towel in the clean water and wipe that section before the soap dries off. Letting any section to dry before rinsing will make it difficult to wipe and result in ugly spots.

Step 6; Once you have cleaned all sections, rinse the car with the spray hose or power washer, again from top to bottom and ensure all soap has been removed.

Step 7; Dry the vehicle using a scratch-free microfiber towel or chamois. The best way to dry car after washing is to start with the windows since the dry towel fibers won’t scratch it.
