I recently brought some of this prestone all seasons screen wash after reading some impressive reviews on auto express and it has won awards.

I then saw some on sale in my local tesco's for £3, and i thought i need to try some for that price. I normally use autoglym screen wash which is really good though its not ready mixed.

Anyway my bottle ran empty the other day and i couldnt wait to try some of this prestone stuff.

I ran the pump so it sprayed onto my window and it cleaned ok, nothing spectacular, but it has one major floor, one it looks like p*ss when it comes out of the washer jet and when it runs down the cars paintwork, it dries yellow onto the car, my car is silver and it looks like someone has wizzed up it.

I cant believe an item that is supposed to be this good could leave a staining yellow colour on the bonnet and rear boot.

Never will buy it again

Thought i would warn any potential people wanting to buy this stuff. DONT.

I bought the same, from Tesco for £3 last month,

I was unhappy with the Tesco stuff I was using leaving streaks on bonnet.

Unfortunately my garage contaminated it with an unknown screen wash when serviced soon after,

so not 100% sure how good it is until I get it emptied again.

How much did you dilute it?

It say's for Spring/Summer, 1 part ScreenWash to 19 part Water, which is alot more diluting that I was used to previously.

I diluted mine alot less than that though.

I've got some too but haven't used it yet...now im put off using it!
