  • A must-have for home maintenance
We keep this handy in a spray bottle and it's great for many cleaning chores and even simple first aid. And it's the simple solution for windows that just never seem to come clean - wash them first with plain tap water and rinse with this. No window cleaning chemicals needed and they come out smudge and film free. Same with car windows. Glad we learned about it. ... show more

This stops and prevents such issues from occurring during this process! Water quality is ultrapure meaning its good for anything but drinking it is not safe at all. If you read up online for the PCB electroplating process it mentions this water is recommended! :) ... show more

  • worked for my field blanks
I needed DI water for some field blanks & couldn’t find it anywhere local or from a reputable online supplier in the quick timeframe I had for a high profile project. I was super nervous to get back all the test results but the blank came back all ND! So for anyone who may need DI water for groundwater and stormwater sampling reasons, I can confirm this gallon did not screw me over. ... show more
