Get read of the fog on your head and taillights
Owning a car comes with many responsibilities. For starters, you have to pay for the gas, the insurance, and all the other necessities. But also, you must always keep your car as clean as possible. Every vehicle has a lot of little gaps and spots that need a detailed cleaning but cannot be reached in a normal washing session.
Cleaning these tiny creases requires something with fine bristles. In these cases, you can use a toothbrush. And these are also useful for more detailed works. For example, if you want to keep your head and tail lights free of fogging and yellowing, you can use toothpaste (especially if it has sodium bicarbonate) to return them to their original color.
