not trying to cause a argument here.....well......hope nothing i've said had made people want to kill me....

erm.....sometimes, i think any rad makers who don't tell people what to use for cleaning a rad is simply because they don't want to, if any of us somehow manage to break a rad, they'll be happy....because you might go back and buy another one = more money for them.

the other thing i can think of, maybe its because they know the words going round in big forums saying using vinega will be give you uber clean rads, so they keep their mouth shut because they think no one will listen anyway, because some watercooling uber god from vinegacleaning.com/forum said so.

in Marci case, and IMHO, i think he just can't be arsed to say anything, maybe he has tried saying water is good enough many moons ago, but he got questioned so many times he just gave up, took a step back, and said 'yeah, if you say so...'

argh, i dont know, its just one of those things that keep going round and round with no ends.

oh, with regards to the powerful car bit, everyone knows they will die from being a bellend on the road, but, you'll never see car makers stop making more and more powerful cars, and they will never tell you to drive like a nanny because they expect everyone to have commen sense, thats just one of those things where money comes into play, rich bellend crashed 200mph car, rich bellend somehow walk away from it, rich bellend goes buy another 200mph car. (see? someone buy a rad, use vinega, vinega thought eatting a chunk out of rad seems fun, that someone goes buy another rad, yet, rad make didn't say a word about vinega)

---------sorry in advance if i had offence anyone, sorry--------
