The Japanese carmaker Nissan has shown off a self-cleaning paint that may mean the end of car washing. The paint repels water, oil and other dirt. It is called Ultra-Ever Dry. It uses a process called nanopatterning. This puts tiny bumps and grooves on things to stop water and oil from sticking to them. Nissan said the paint has "responded well" to many weather conditions. It added that its engineers will continue testing the paint.

Nissan said: "Washing a car can be a chore – and a costly one at that." It has no plans to use the new paint as standard on its cars, but it may be an option in the future. The paint is being tested on the Nissan Note car. Nissan said this car takes the stress out of driving. It said it is thinking of new ways to make people's lives easier." Nissan said it would continue to use cutting-edge technology for the everyday problems that customers face.
