You will often find in many DIY recipes that Distilled Water is part of the ingredient list.
So what is the difference?
Can I just use tap water or bottled water?
What will happen if I use tap or bottled water?
What can I do if I don't have distilled water?
THE DIFFERENCES - There are many minerals and impurities that are taken out in the purification process to obtain distilled water. In short contaminants and even bacteria. Not that is all bad - we need some bacteria - but others can grow and reek havoc on your project.
If the recipe calls for distilled water do yourself a favor and use the proper ingredient.
SUBSTITUTES - If you simply have to finish your project and you don't have any distilled water - you can substitute filtered water that has been boiled. It has to be a very high quality filter - no the Brita water pitcher filter. In the end if you choose this route - maybe make a small batch so if is should turn - you are not out too much.
PS - Bottled water - is all too often water that has literally been filled from a tap. Do you your research when it comes to bottled water.
