Please, do you know how I can remove cloudy white mark from inside my elderly crystal vase,( inherited from my Mother) without damaging the vase?? I have filled it with white vinegar and soaked for a couple of days, then washed again in soapy waterand used bottle brush, but marks are still there.

Crystal can get that clowdy appearance with AGE. I have enquired about that too and sadly there is nothing that can be done. It's not a cloudiness on the surface, but in the crystal itself.
Sorry

Thanks for that Raewyn, I have used many litres of vinegar trying to clean it. I knew that someone visiting this great site would have some information.

Well I hope I have the answer as I have done this & it works a treat. First never put crystal into the dishwasher that is the cause of some of it. Get a mild solution of bleach (janola) & water spray with it leave a few minutes & wash off with warm soapy water. Do let me know if it works for you.

Thanks for that Lyn, I have tried twice this morning, filled the vase with water and added bleach, left for a few minutes, then scrubbed with bottle brush and washed in soapy water, but the problem remains. I will try again tomorrow, with a stronger solution. I never put crystal in the dishwasher.

Did I read/hear somewhere about denture cleaning tablets working on this problem???:-( Anyone know if it would do more harm than good? Have a vase myself that could benefit from something that works!

Lyn (P.Nth) not sure about crystal, but the denture tablets work a treat when left to desolve in the toilet bowl.
I use the extra strength,
