The Sonax x-treme, we are so far very satisfied.
+ The currently set here Product description, especially with regard to cleaning performance and consumption, true
+ At any single part Sonax and water proof up to -30 degrees good (as friends of ours)
+ We use 1 part Sonax / 2 parts water and had - not only as measured - by up to -25 degrees no problem (our wiper washer nozzles, however, are heated)
+ The agent is really free of streaks and also has a good cleaning effect also with respect to salt and dirt
+ Foaming (know no antifreeze without) is lowest
+ Price / performance very good
We can only recommend this antifreeze.
