i found that some brand (diy silicone coated) wiper blade is tilt to one side. also the aero shape.
after fit on car with LHD arm they squeek loud until i swap direction.

neither wet nor dry produce noise now.

probably the glass has something to do with it
you can try remove the rubber strip and flip if sideways

how to swap directions? mine only goes in one way

some brand can detach center piece. some cannot
eco shop rm2.40 wiper cannot

Bought rm10 tepi jalan wiper almost a year plus, till now works perfectly

tepi jalan cost went up 15-20 d

Nowdays yea, but a year plus back i bought rm10, that time went to maybank then this sales person told me rm10 for the wiper, then agreed and installed it

Now most thing went up, nothing going down 😢
