Question 980554: I need to mix a cleaning solution that would spray out of a bottle and contain 70% rubbing alcohol to clean lab surfaces. To save cost, it makes sense to add water to some amount of alcohol yet maintain the 70% level. Average spray bottles likely hold about 25 fl ounces or what about 800 ml? What should my solution look like? Thank you. Leann
