Car wash workers can increase their salary by acquiring additional skills through training in areas like detailing, customer service, and equipment maintenance. Pursuing certifications in advanced detailing techniques or eco-friendly washing methods can also enhance their expertise and value to employers, leading to potential salary increases.
