Everything is different even the bathroom cleaner

Here's a good one. Usually in the US, I was used to cleaning stains etc with bleach. Bleach is really a mixture of things but mostly Sodium Hypochlorite and some other sodium compounds. In Thailand it is almost impossible to find bleach. What they use instead is a cleaner containing a diluted amount of Hydrochloric Acid. Ouch. Sounds dangerous and definetly smells different.
