Car wash full on March 1st. Does it mean something here or is it just coincidence?

...that every single car wash I went to today, and that was at almost in every single garage within a 5km radius of home, had queues of 8, 9, 10 cars waiting. and that was for the whole day.

Like I say, is there something about this day I didn't know, some superstition about things being cleaned on the 1st March or is it just a coincidence?

On the first of March 1643 there were gallant Polish knights who used the reflectiveness of their armer to blind their enemies in order to defeat them.

And from that day till this, on the first day of the third month, Polish people have cleaned their armer, chariots, horses, bicycles and today cars.

Naw just kidding, just a coincidence ;)

Nice weather makes people have their cars cleaned, I was thinking of doing the same today.

Really? Just when it was getting interesting. Very disappointed.
