Mikko Paretskoi,

the inventor of the Windshield Wiper Cleaner

died as 70 years of age in 2005 in Vantaa, Finland.

He was born by the lake Ladoga which belongs

nowadays to Russia.

In 1970 he was driving in bad weather not seeing

very well the road ahead.

Then he was thinking to get solved the dirty wiping

problem. He grinded thin and narrow line on glass 

above the wiper's rest position, so that wiper went 

over the line every wipe.

For the grinding he built whole set of tools.

The invention had to be tested if it is doing

what supposed to be done and that it was not 

weakening the windshield. 

Mikko Paretskoi was rewarded of his

invention by two insurance companies 

and his invention in Brüssels Invention fair.

Safety grooves for windshield wiper cleaning
have been very popular in Finland.
Some car makes have offered grooves
several years. Car inspection stations have
also offered about 20 years grooves to be grinded.
