Early on I was taught to only every use deionised water, to avoid the introduction of other chemicals, impurities, etc. However, I have recently heard that using good quality tap water may be in fact better than deionised/demineralised water, as deionised water is not in a stable state and so can in fact pull minerals out of the specimen. I would love to hear what other people use and what your thoughts may be on this.
