Is Using Dish Liquid to Wash Your Car Really Harmful? The Truth Revealed

The age-old question of whether or not dish liquid is ok to wash your car has been debated for years. While some might argue that it could be a quick and dirty solution, the truth is that using dish liquid on your car's finish can actually be quite harmful. Let's dive into why this is the case and why you should always use a dedicated car wash soap.

Harsh Chemicals

Dish soaps are designed to cut through grease and food residues, making them powerful in a kitchen setting. However, these harsh chemicals can be damaging to your car's paint. Cars have protective coatings and waxes that keep the finish looking glossy and protected. Dish soaps, due to their strong surfactants and detergents, can strip these protectants away, leaving your car vulnerable to scratches, dullness, and other damages over time.

Ph Balance

Many dish soaps have a high pH that is not suitable for automotive finishes. This alkaline pH can be too abrasive and lead to dulling and potential long-term damage. Over time, the harshness of the soap can degrade the surface of your car, leading to a matte finish and diminished appearance. It's important to use products that are pH-balanced to avoid such issues.

Lack of Lubrication

Dedicated car wash soaps are formulated to provide the necessary lubrication needed during the washing process. This helps prevent scratches and swirl marks that might occur when using other soaps. Dish soaps, on the other hand, may not offer the same level of protection. This means that even a gentle wash using dish soap can still leave your car's paint vulnerable to damage.

Residue

Another issue with using dish liquid is the residue it leaves behind. This can attract dirt and make it harder for wax and sealants to adhere properly. Additionally, the residue can further damage your car's finish when it accumulates. It's essential to use a soap that rinses clean and leaves no residue behind.

Special Recommendations

For the best results, it is always advisable to use a dedicated car wash soap. These products are specifically formulated to maintain the appearance and protect the paint of your vehicle. They provide the right balance of cleaning power and protection without causing damage.

It's also important to use the right tools when washing your car. Special sponges and rags designed for vehicles will help protect the finish during the washing process. Neglecting to protect the tires and mudguards can also lead to staining and damage. Ensuring that these areas are cleaned properly will prevent debris from re-staining the bodywork of your car.

In some cases, certain dish liquids can be useful in car detailing. For instance, Dawn is often used to strip vehicles when there is a buildup of residues due to improper soaps and detergents. However, for regular washing, it is not recommended due to its harshness and potential for scratching the clear coat and promoting oxidation.

To conclude, while the allure of using dish liquid as a quick car wash solution might be tempting, it's important to avoid it in favor of a dedicated car wash soap. These products are designed to protect and maintain the beauty of your vehicle while ensuring it stays looking its best for as long as possible.
