Using too much car soap can lead to a number of problems. It can cause the soap to dry on the surface of the car, which can leave a chalky residue. This can be difficult to remove and may require additional scrubbing or the use of a separate cleaner. It can lead to oversudsing, which can make it more difficult to rinse the soap off the car. This can lead to soap streaks and spots on the car's surface, which can be unsightly and difficult to remove. Additionally, using too much soap can lead to a build-up of soap on the car over time, which can cause the paint to become dull and faded. This is because the soap can strip away the protective wax layer on the car's paint, leaving it more vulnerable to damage from the sun and other elements. Platinum Palm's Concentrated Car Soap Drops eliminate the urge to over-soap. Simply drop into your bucket and spray directly with a hose. You'll get a consistent wash every time.
