The wipers on my car have been screeching since I bought it about three years ago. I put new rubbers on them a while back, but that didn’t fix it. I don’t drive in the rain frequently enough for it to be a major bother, but yesterday, I was near a Supercheap Auto, so I went and spent the money on some good quality replacement blades.
They work smoothly and perfectly. After three years of screeching, a silent wipe is almost unfathomably satisfying.


Anyone else miss the days where you removed the two metal spines and just replaced the rubber bit? cost was in pennies too.
This is still available on some cars. Honda will sell you just the rubber insert. (Probably others too) It comes with a graphite powder on it to help you slide it into the wiper blade. It is about $5-8 instead of $40 for the blade
As I said in the OP, I tried that and they still screeched like a stuck pig.
I completely glossed over that! I’ve not the rubbers for sale in the UK for decades! Usually the blade supports just need a wiggle and some WD40.
The new silicone and semi-silicone blades are good, just a shame they are £30 a set.
