Thanks. I also have never seen S100 in Thailand, though I'm going to look at the Klong Thom machinery market on Saturday. They have lots of stuff.
What is FAB, and do they have spray-on cleaners that are the equivalent of the S100 stuff? I have a decent supply of S100 wax, so it is a good cleaner that does not require too much elbow grease that I'm looking for - and one that does not leave a lot of residue that itself has to be cleaned off.
Not sure if THE most popular but certainly one of the most popular Thai brands of laundry detergent. The one to use for cleaning bikes comes in small sachets of a jelly like consistency. NOT powder. Apply with a toilet brush or similar utensil. Can be hosed off, leaves no residue.
