I’m having trouble finding distilled water in my country. What should I do?

The important thing is to find water with very little magnesium and calcium in it. Some bottled water has more minerals in it than others. So you could try to find bottled water with a small amount of minerals in it. 

Another option is to purchase a reverse osmosis water filter. Reverse osmosis filters remove everything from your water. You get very pure water that way. You might be able to order a reverse osmosis filter locally. Or you can order one online. There are ones that you can attach to your sink quite easily.
