Weird film on drinking glasses...
We moved house in April, and probably about a month later, we started noticing a strange film on our drinking glasses. The strange thing is that we only moved 1/2 mile, so we're still on the same city water supply. We've never had a problem with city water, so why would this film start appearing? It's baffling!
To describe the film: it's white, spotty, and seems most concentrated when water has stood and evaporated in a glass. It never comes comepletely off, even with sustained scrubbing.
We really want to prevent the film, but we can't figure out if it is related to our dishsoap, or to our pipes, or to our drinking water. Anyone have any advice?
Some factors that may or may not be affecting the situation:
1. We don't have a dishwasher, so everything is being washed by hand. (We were handwashing at the last place, too.)
2. We have not changed dishsoap in years, so I don't think it can be that. (Incidentally, we use Palmolive Aromatherapy, lavendar scent)
3. We have always air-dried the dishes, but have just noticed that towel-drying seems to help prevent the film a little.
4. We do live in an old house (1929) so the pipes might be a problem.
So... what do you experts think? Calcium? A weird interaction between dishsoap and water? Aliens?
I sure appreciate your help. We just got married and gor a whole bunch of new drinking glasses which we are afraid to use for fear of the dreadful film. :)
