This class Klassiger cleans everything oxidized easily or quickly, and there's enough around us. Yesterday alone - and therefore the review;) - I was able to show a young telecom service technician, what makes this spray in a telecommunications distribution box. Was it but the simple oxidation of the copper wires and terminals, the. First the testing and then my modem could go haywire and letzerem to my "delight" ultimately missed a steady red T-DSL light
Especially everywhere where bare wires are anchored in terminals and contacts obtained via plugs, switches or (rotary) sander, this is by means of an enclosed, long and thin Schläuchchens perfectly applicable and to be dosed detergent easily worth gold.
If one uses the old contact-60 (this applies my review, with contact-60 Plus I have no longer experience), one should not forget after the exposure phase, the area to flush with contact-WL and with contact 61 or a resin-free oil to Contact "seal".
Sure there are comparable, but once you're satisfied, you can not change in general ... and I am very satisfied!
Note .:
Whoever needs a means regularly, I recommend the 400ml version.
