88 W124 Single Wiper Arm

[Lim]

Hi

The paint on my wiper arm has faded (turned grey), and the part attached to the wiper blade has rusted a bit due to paint peel-off. I would like to remove the wiper arm, and spray it with some new black paint.

However, the wiper arm looks quite difficult to remove. Any good tips to remove the wiper arm?

When the arm is removed, I would also like clean and lube the moving parts. Is it suitable to use lithium grease to lube the moving parts?

Thanks.
