I had indeed hoped that when using the sponge, the discs are now clear and you can start driving immediately, but it is in practice, at least for me, so that the discs are still toned after wiping. However, what is good, is that the slightly fogged windows are quickly realized, even when adjusting the ventilation on the lowest level and even without air conditioning, and not only immediately after the wipe, but also on the next trip (how many rides the effect will last, I could not test).
My comparison test against the untreated disc: I have a half of my windshield wiped with this sponge and the other half during the wiped page after a short time and was not free, the ungewischte side was still steamed up even with my Ankunf on goal.
