19. A Flawless Finish with Clay
You can find random, yet perfect cleaning products for your car in your laundry room, your bathroom and your kitchen cabinet – and this next one will send you straight to your kid’s art supplies box. Clay, who knew? This unexpected car cleaning miracle tool has a very clear purpose: to help you pick out all those bits that water won’t remove. Surely, you can use a clay bar made especially for cars, but if you’re on a repurposing mission, any leftover clay will do the job flawlessly and will leave your ride utterly shiny.
