“Cleaned by physics vs. cleaned by chemistry.” In the late 1990’s, to this tourist, it appeared that U.S. appliances were designed so that ever-more-sophisticated soaps and/or soap marketing would get laundry clean, while German appliances were designed to use physics to get laundry clean. The latter had gotten so good at it that for years they’d been competing by promising not cleaner clothes but to reduce the electricity and especially water required to do a load of wash.
The fabrics in clothing sold in 1990’s Germany were much higher quality than the kleenex clothes sold in the U.S.A.: thicker, stronger, less likely to wrinkle. At the time I thought this was because German consumers complained before purchases more, both to each other and to the stores*, but perhaps it was also due to post-purchase complaining after clothes designed to be worn twice and soap-laundered dissatisfied chatty consumers rather egregiously when worn four times and agitation-laundered.
In both countries, water in rural creeks and rivers formed persistent foam that did look like soap bubbles, originally white but turning yellow with dust as it was carried downstream. But friends said this was caused not by household soaps but by artificial fertilizers in runoff from farmers’ fields.
