Best Car Wash Soap for Foam Cannon : Buying Guide

Cannons are attached to power washers and can accommodate thick foam, provided you use the appropriate car soap for your cannon. You may be surprised how many options there are when you look for the best car soap for foam, so we prepared this buying guide to ease your task.

Cleaning Power

Soaps are very different from detergents, so you need to find out which is best for you. Soaps use a lot of natural ingredients, like vegetable oils or animal fats. They are generally mild cleansing agents used for regular cleaning. On the other hand, detergents are much harsher, containing synthetic components like petroleum and coal hydrocarbons.

The kind of water used for washing your vehicle is essential, too. If your water is hard, the detergent will be the right choice because it tends to soften water. If you use a soap with hard water, the ugly stains or white residue instead of the sparkly clean surface.

The advantage of detergents is that they can be used with any type of water.

Appropriate Formula for the Surface Treated

The right pick of the soap will depend on the surface you need to wash. Several different materials are incorporated into the car: rubber, plastics, glass, and metal with the paint.

Car soaps are usually pH neutral and mild, not allowing the car wax to get stripped off. They also do not leave marks on the glass or plastic part of your car. Many of them contain wax additives to protect the paint additionally.

Foam

The amount of foam that soap can generate using a cannon is significant because it soaks the dirt that builds up on vehicles, softening them and chemically breaking them up. Hence, they come right off with the sponge or with a bucket of clean water.

It is not advisable to scrub forever in order to loosen and remove the dirt because the scrubbing process will cause streaks and, in some cases, even scratches on your car’s paint. So the right amount and thickness of the foam is the key.

But you do not have to worry; any soap for foam cannon designed for that specific purpose will create the rich lather – the only thing you need to check are users’ directions and experiment a little with water-soap ratios in your cannon.

Scent

Most of the soap on the market are scented. They offer a wide variety of aromas, like cherry, apple, or honeydew. If you do not want your car to smell like fruit, you should look for an unscented formula. Or at least one with a relatively mild aroma.

Tips & Tricks for The Best Car Pressure Washing

Being a huge time-saver, pressure washing should be more effective with these several tips:

• The car should be cool to touch – choose the shady place and a mild day.
• Always rinse the soap before it completely dries to avoid white marks.
• Professionals recommend pressure washing from top to down.
• Pour lukewarm water into the bottle and gently mix it by swirling the bottle.
• Protect your plants and pets if you are using detergents because they are so harsh to the environment.
• With a seriously muddy vehicle, pre-wash it with clean water to remove the heavy dirt off. Then apply the foam.
• Wear protective equipment: waterproof boots and clothes, eye protection, a breathing mask, and earplugs.
