In Shrek there is the optional intensive washer, with the small bottle on the right trunk wall, that says "use only intensive washer fluid,...."

The local dealer says NLA. The local BMW dealer (my Beemer had an intensive washer as well) says NLA.

What do I put in that bottle? Is the extra cleaning power due to the fluid itself, or is the pump a special high pressure unit?

I just pour windshield washer fluid in there. I don't use it often anyway but it doesn't seem to be an issue.

I think there is a special intensive cleaning fluid you're supposed to put in it, although I've never used mine.

When I first bought my car the dealer had it filled with the intensive fluid. I used it all up thinking it was the main wash wipe for the car. Doh!

I dont recall it being that great and didnt shift the bugs off the windcreen like I think its supposed to do.

Never have got round to buying any more for it!

The bit about the pump being extra high-powered made me laugh. It's more like a little dog weeing on it! :-)

John,
agreed. That answers the first question.
Now for the second: is there any specific product to use in there? the BMW fluid (now NLA) was pretty good at dissolving squashed bugs.

I read somewhere on a previous post the "intensive" washer fluid is notorius for mineralizing and stopping up the jets. I believe, if memory serves correctly, that standard washer fluid was best.

GeorgeK

Good to know. That migh explain the calcium...mine I have in my tubing and jets. Those have replacements waiting to be put in already. Guess it is a redundant setup then. Too bad, I kind of want it to work as it should, but don't want to have clogging problems.

I fill mine with the regular stuff, and use it when I am feeling especially 'intense'.

I have read that using the intensive washer is not a good idea as, if it leaks, it drips right into your very pricey ABS control unit.

Marc,
Very true. It is one of the 2 main reasons for relocating the ABS brain. the other is rain water following the wiring loom into the connector and corroding it away.

I've always thought that I'd put a RainX (no affiliation) product in the intensive washer and use it to treat my windshield now and then to a rainx wash.

I've never done it, but it seems like a good use for that silly thing!
