Sheesh, Exeter isn't that far from Zurich, they have a home hardware still don't they? Why not try Zehrs to see if they have some in the cleaning section.
Sheesh is right... the post directly before yours said I got some and used it already.
Also, as mentioned in the OP, the local grocery stores only had the lemon stuff.
The Home Hardware in Exeter is also... odd. Chunk of it is old used stuff, one corner is a sports store, the other corner is The Source, which half the stock is shrink wrapped used business phones. They had no ammonia.
Grand Bend Home Hardware had it... of the 9 stores I tried, it was the only one that did.
