Techniques for CollectorsIron Out and Tap vs. Distilled/Filtered Water Question
14th Nov 2017 18:52 UTCScott Rider
However, earlier this year, my water has tasted odd, and there is definitely a build up on my faucets... I think the city changed its water source, of which I have not looked into, but the water sure tastes really odd.. My neighbor reported the issue and never got a reason of why...
Anyway, my question is that the recent build up of white film on my specimens due to the perceived increase in the waters hardness? My recent cleaning batches of Lake George/Devil's Head material have a nasty hard white encrustation of which I haven't had to deal with before. This was not a problem prior to my water changing... Before I would just would wipe or scrape the white film off easily, but now its much much harder, much more annoying and doesn't even scrape off easily anymore..
Should I keep using tap water or should I start using filters or bottled distilled water? Would the film decrease using filtered or distilled water? Or is it more a product of me using too much SIO? I don't think I added too much but I also haven't cleaned anything in last year until recently.. But I am certain the proportions are good.

Tonight I'll do an experiment and have 1 batch of acid water with the tap and 1 batch using Brita or Pur filtration. If I perceive no difference, then the calcium build up isn't the issue.. Its just most my friends use just plain ol' tap water and don't seem to have the issues I have...
One suggested using this, start with SI and through it into a CLR mixture, then many, many days of clean water to rinse everything off... Has anyone tried using SI then CLR?

First of all, in most areas, acid rain (water) is not nearly the problem it was some years ago.
Hard water does leave a calcium lime scale in those areas where the water is really hard and there I would use dehumidifier water, or equivalent, when possible. In other areas, where the water is not so hard, tap water or dehumidifier water works just as well.
Let's be pragmatic here; cleaning and preparing hi end specimens demands some special treatments such as distilled water, but cleaning a routine ordinary quality specimen does just fine in clean tap water. In areas where the water is not so hard, don't waste time, money, and energy when tap water does just fine for routine specimens. CHEERS.......BOB

I bought a carbon block filter and installed it in an outside station. I hook the hose to the filter and run all my water through it that I use for cleaning. Maybe it is overkill, but it works well for me and I seem to have less problems than I did before.
I made the mistake, one time only, of cleaning specimens with HCL and not getting them completely neutralized. I then put them in SIO and tried to remove the remaining iron oxide. They ended up covered with a dark green crust that nothing would take off. I was never sure what it was, but I am certain it was related to the chloride remnants from the acid.

In those situations where you have chlorine odor in water you also probably have high iron as well and probably other chemistry that is messing with the IO. The carbon will also remove the iron, but is an expensive way to do that, at least in large quantities (I know cuz I have a well with high iron and slightly low pH, which uses calcite for the pH and reverse osmosis using salt to remove the iron).

I have on a few occasions witnessed greenish stains appearing after SIO and clean water treatment. Especially with porous feldspars. As mentioned above, I attribute these to Fe2+ compounds of some sort. However, allowing the specimen to air dry for a day usually causes the green to disappear (I assume by air oxidation of Fe2+ to Fe3+).

Steve, yes always soak in clean water after IO use, or any chemical. Air drying will reduce the green cuz all colors look darker when wet, but next time try a little acid in there if safe for the mineral. Could be that there is re-oxidation also. Yes, I've had the same problem with feldspars going green.

Living in NW IL my small city water does have plenty carbonate in it. 1 of the 3 wells is a half block away and I know the operating crew well enough, good guys and also have participated in random quality testing paid for by the city. All limits are properly met.
That all said- as I noted- we do have higher end of carbonate limit.
My tip off was when taking quartz out of the IO bath and putting in the clean clear (tap water) rinse, minutes later that water was cloudy white.
It would settle after a while, but be obvious when pouring out the rinse later... I had scrupulously removed the iron clays before IO- only transparent iron stain left to remove. This was clearly a IO residue.
I have switched to rinse water saved from dehumidfier for the rinse.
