Car detailing clay is one of the quickest, most efficient ways to remove imperfections on your car, but don’t let its success fool you into thinking that one bar will suffice for months. But is there ever a time where it is suitable to reuse it?
The short answer to this query is no, for contaminated clay will not perform the task you need done. The ‘eye’ test is not a prudent one to use for clay detailing because occasionally it appears as if the surface of the bar is ‘clean’ when in reality impurities are embedded into the substance. You should always err on the side of caution when it comes to clay, because since it is a substance that is rubbed it could be causing deep scratches below the surface if the bar has been previously used.
“Detailing clay should be thought of similar to something like a syringe, where every time it is needed, a fresh, sterile one is used”
Detailing clay should be thought of similar to something like a syringe, where every time it is needed, a fresh, sterile one is used. Because it is a relatively inexpensive purchase, this should not be an issue most of the time. Obviously we all want to stretch our dollar, but if the same clay is used routinely, it will damage your prime coat.
If you are in an absolute jam and need to use the same piece of clay you’ve used several times, fold it as many times as you can to get any area that looks free of debris. It is nearly impossible to get dirt and sand out of previously applied clay, so you are fighting an uphill battle unless it is smooth. If you find it is a necessity to reuse a bar, do a spot test, preferably around the bumper where accumulation of dirt is frequent. If you are able to perform a solid test without resistance while rubbing, you should be good to go. Remember, even though clay is shaving down bumps, the method of running it across the paneling should be fluid.
What Can You Do Until You Acquire More Clay?
Most people are not going to have clay on hand every time their automobile desperately needs it, but in lieu of using an old bar, spraying the paneling with lubricants and using a microfiber towel can serve as a ‘placeholder’ until you get more. What this does is remove as much contaminant as can be done with a rag and seals the remaining imperfections to the best of your ability with detergent. The reason why this is important is because if these bumps are allowed to be exposed directly to the elements they will scratch much faster and be harder to smooth out once you acquire clay.
Rely On Expertise
In truth, professional auto detailers should eliminate this problem for you entirely, as they never reuse a bar of clay. Experts on its application always use a new piece to maximize the positive effect on the car’s exterior. Particularly if this is done frequently, the shine and smoothness of your vehicle is unbelievable and looks as if it just came off the assembly line.
