You may want to change only the rubber part or switch to those "aero" or "hybrid" blades which are more flexible.
Maybe the cap or the coolant tank itself has become brittle over the years.

Fortunately 400 mm ones are easy to get from auto parts stores (Tridon brand is common here) but none seem to cope well with the extreme curvature of the front glass.
Second one being that the coolant tank is down to just under minimum.
Since the car got parked up in July last year I've had it running a handful of times and last time was a cpl of months back.
Seems to make me think there's a weep or leak somewhere, or (hopefully not) a head gasket issue. I thought I'd found and sorted all the hose connection weeps.
Anyway car has had it's first clean in about a year, so it looks a lot nicer.
Take a break, make a journey (at the moment we have 10°C and a slight drizzle).Too hot (over 30C) to keep going.
The filing fur might suggest a balancer that is/was ( perhaps a previous balancer ) hitting the TC/oil pump . Seen that before , once spotted one at a wreckers where the balancer had worn a hole into the oil pump , right up till that moment I was trying to figure out why a very clean looking 900 was in the yard.Valve cover, timing chain cover, head gasket, or crank seal.
That gunk shouldn't compromise operation but might shorten the life of the sensor. Hot oil or rubber on there won't make it last longer, that's for sure. The Hall sensor is a magnet, and it looks like you've got some filings fur on there too.
