It is recommended to use 70% isopropyl alcohol as a cleaning agent for your car cleaning purposes.

However, using isopropanol in high concentrations, leaving it on the car paint for too long or using it on freshly painted cars can potentially damage the clear coat or paint and can strip and make it dull.

How to Use Rubbing Alcohol on Your Vehicle?

Rubbing alcohol can be used on car paint to remove contaminants, adhesive residue, or light stains without causing damage when used properly.

Here’s a step-by-step guide on how to use rubbing alcohol on car paint:

• Mix isopropanol alcohol with water in a 50/50 ratio to reduce its concentration and minimize the risk of paint damage. You can adjust the ratio depending on the level of contamination, but it is always best to start with a milder solution.
• Park your car in a shaded, well-ventilated area and ensure the paint surface is cool. This will prevent the isopropanol from evaporating too quickly and minimize the chances of causing damage.
• Before applying the diluted isopropanol to a larger area, test it on a hidden part of the car to ensure it does not cause any damage or discoloration.
• Moisten a clean, lint-free microfiber cloth with the diluted isopropyl rubbing alcohol solution. Gently apply it to the area you want to clean, using a circular motion to remove contaminants or adhesive residue.
• Quickly wipe off the alcohol after applying it to avoid damaging the clear coat. If necessary, repeat the process until the contaminants or residue are removed.
• Once the contaminants or residue are removed, thoroughly rinse the area with water to ensure no alcohol residue remains on the paint.
• Use a dry microfiber cloth to gently dry the area and remove any remaining moisture.
• After the paint surface is clean and dry, apply a high-quality car wax or paint sealant to protect the paint and maintain its shine.

Remember that rubbing alcohol should be used sparingly and cautiously on car exterior. For regular car washing and maintenance, it is recommended to use dedicated automotive cleaning products specifically designed for this purpose.
