Some of these products can damage the paint. Among suggestions from the Council, work in the shade. Flush off as much of the road dirt as possible before applying the suds. The sponge, towel or washing mitt should be absolutely free of abrasive grit. Pay attention to those crevices underneath the vehicle that accumulate mud and road dirt, especially important in climates that use salt to melt snow.
Excessive pressure can loosen trim or moldings.
Automotive chemical manufacturers have developed new products that make the finished job more impressive. Tires and black plastic trim, for example, can be made to look like new with protective dressings. After vacuuming the carpeting, upholstery and door panels, a good fabric cleaner, shampoo or spot remover followed by a protective spray can bring drab fabrics back to life. The padded dash and other vinyl areas can be cleaned and protected with wipe-on or spray products created specifically for these surfaces. However, regular washing and waxing can keep one s vehicle looking new for years longer.
