Hey guys,@jkallmeyer, @john-christian,
you can use Rewoquat diluted with Isopropanol up to 20% but the results are way better with the full strength. Like I said it is just a very high concentrated detergent (tenside) similar to the one used for laundry but much higher concentrated. The more you dilute it the worst it works. A good thing is that you can reuse it several times what reduces the costs dramatically. Just let the Rewoquat-sediment solution rest till the sediments sink down. Than you can decant Rewoquat and use it again 😉
cheers
