First, visually inspect the areas with concentrated minor scratches and assess their depth; clean the scratched areas with a dry towel to remove dust and other contaminants; apply some toothpaste (or car wax) onto the dry towel; rub the scratched areas back and forth repeatedly; check if the scratches have been completely removed—if not, continue rubbing until they are gone; use a damp towel to clean the treated area and remove any residual toothpaste. First, determine whether the minor scratches on your car have exposed the primer. Gently scrape the scratches with your fingernail to see if there is any resistance. If there isn't, polishing will suffice. If there is, use nail polish to address it. If there is no resistance, it means the scratches are not deep and have not reached the primer. In this case, first dampen a cloth and wring it out (so it feels slightly moist). Pour a small amount of fine wax onto the center of the cloth (about the same amount as when squeezing toothpaste), spread the wax evenly on the cloth, and then gently rub the scratched area with the wax-coated part of the cloth. Rub along the direction of the scratches. After five or six back-and-forth motions, rinse the scratched area with clean water to check if the scratches are still visible. If they are gone, the scratches have been polished away. If not, simply repeat the above steps.
