My go to shampoo has always been Adams’s but when I heard about Koch Chemie it got me really excited to see what they had to offer. After doing a couple of washes with GSF I realized I’d found a better soap. It’s a bit slicker than Adam’s and a lot thinner so it pours easier. It foams just as good but my favorite part is that it doesn’t reactivate after foaming. It’s PH neutral so it’s safe for waxes and sealants.
