here is an additional read on “sick glass”

I would certainly use caution or if it is very bad and valuable, send to someone who does this…again caution..

good luck

[URL removed] NEVER fill or place a valuable piece of glass in HOT water (unless specifically made to endure hot water temp)…valuable being the KEY word…you may quickly end up with WORTHLESS glass…

I always use hot water and vinegar. This is great for removing deposits, I also use this to remove mineral build up on my stainless steel tea kettle, works every time.

I have never had to use anything more harsh than vinegar. I just mix about half and half with water and let it sit overnight. The minerals usually wipe right out!

Sometimes if an item is too large and I don’t want to use that much vinegar I lay the item on one side and turn it every few hours.

Make a paste using white vinegar and baking powder. Spread it on the stained surfaces. Let stand for a few minutes, longer for harder stains. rinse.

Sometimes it takes a couple of applications, but this has worked for us in the past.

believe it or not I used my moms denture tablets. let them sit over night worked great

Hope this helps!

Vintgar and water.
BEWARE when using toilet bowl cleaner…
not only is it EXTREMELY damgerous to breathe the fumes but,
IT CAN ETCH old glass and crystal leaving it permanently cloudy.

Hi, I use toilet bowl cleaner, be careful of the odor and wear gloves, This works real well on old planters too.

Ditto on the toilet bowl cleaner. Can’t recall the chemical in it that does all the work but wear gloves and rinse over and over again. It works.

Yes, vinegar and water. I used vinegar back when I boiled my baby bottles. Kept the bottles clean and shining. Always smelled like I was pickleing tho.

I also sometimes use CLR.

I use straight vinegar, works fast on glass, also on sprayer nozzles in kitchen and bath. You would be surprized how stopped up and restricted they are. Just set in a bowl or bag them.

I use straight vinegar and if there’s any alkaline residue left, pure table salt on a damp sponge will cut it.

I use CLR. It is great for all kinds of lime stains, damage from dishwasher water temperatures, and age.

I have a way to remove build up/deposits that is a bit unconventional… figured it out by accident really… make up a batch of simple jello and pour into the item with the build up, let it set up and then remove the jello….I don’t know if it’s a fluke or not but it did work twice now!! LOL

I haven’t tried this on glass, but after all else failed, I got really bad mineral deposits safely cleaned out of a Hull planter using Dow Scrubbing Bubbles. The pot was glazed and is completely shiny in the interior, now. It did take a couple of days of soaking, using a scrubby and re-applying to get the job accomplished.

I’ve added just a cup of full strength vinegar (no dishwasher solution) into dishwasher and (set it for steam dry) and have had minerals disappear from my glasswares.

Thanks I will give that a try. I have a Fred Press Carafe with Blue Horse Pattern which is stained. Thanks so much.

White Vinegar and Water

Thanks for all the info I will be trying these!!!

I was going to say CLR, but vinegar and water sounds like a safer bet. I wonder if that would work on candle wax, too. I’ll have to try it.

A product called lemi shine is the best product I have ever found. My hard water had the dishes in my dishwasher coming out so coated it was sickening. I tried CLR then washing by hand after soaking, but then discovered lemi shine. You put it where you would put the dishwasher soap, then put the dishwasher soap in the smaller dispenser. I tried CLR, vinegar, and even lemon kool aid, but I LOVE my lemi shine. Saved all my dishes. They come out sparkling!

Good luck. :)

i just get lemon juice and let it sit. vinager works good too. i use lemon for the shower head and it unclogs it FAST. add some table salt in the mix and its even better. just put on the lemon and scrub
