Car-wash plastic for rear wiper

[175gt]

It's always bugged me, what protection is the wee plastic sheath they give you at a car-wash meant to give the rear wiper that the front wipers don't need? Just can't work out what it's for?

It's just a wee plastic bag that you put over the wiper. Don't see what benefit there is, though. And, if there was any, why only the rear wiper?

Wash your car yourself, you lazy bugger.

I do normally. Was just thinking of putting it through a car wash to get the underside sprayed to get rid of some of the no doubt accumulated salt.

I can kind of see the thing about the wiper being exposed. Not sure I see how the bag stops the the brushes ripping the wiper off

I'm very reluctant to put cars through a car wash, each of my last 3 cars went through one only once. I never put the plastic bag on and each went on to new owners with intact rear wipers...;)
