M.O.T advisory

[Nimby]

I had an MOT advisory that the rear wiper was smearing.
Turns out the wiper is fine; the problem is dog-snot on the inside of the window!

Try owning a Bassethound. Those dogs create enough slobber for a swimming pool.

We call it Dane art in our house.
Change your garage. The rear wiper is not a testable item.
