I'll be getting my trays in some weeks time, and there's a question that worries me.
I live in a place where the water is very hard. Apart from its horrible taste (you get used to it eventually), it forms deposits in kitchenware, plumbing... everywhere... and I'm afraid it will happen to the Invisalign trays too

The only solution is using bottled water (to clean the trays) or getting a water softener.
Do you think it's worth to get some domestic softener device? I've seen small ones that attach directly to the sink faucet and look pretty convenient.
I always wanted one (my dishes look dull, the glassware get Calcium and Magnesium stains if I don't dry it inmediately) and now it seems the perfect time to finally treat myself with one

Any comment is much appreciated!
