My Head Teacher has asked that I wash all the glassware and rinse in 'rinse aid in preparation for a titration prac... I have bought some good old home brand rinse aid which I think is designed for use in dishwashers. I don't have a dishwasher, so was planning to rinse in the sink. Does anyone know how much I should dilute it by? I don't want it too strong, but also don't want it to not work!
Thanks in advance,
Meg
