allanb Posted March 30, 2011 Share Posted March 30, 2011 We have been trying to remove stains from the inside of a glass decanter that has been in use, off and on, for forty years or so (not cut glass, and not an antique). It's been used mostly for red wine but the stains show no trace of red; in fact they're really colourless.We have tried soaking it in (a) vinegar; (b) Steradent; (3) Calgon washing machine water softener; (4) a "Finish" dishwasher tablet in water (not all at the same time!) None of them has made any visible difference.Does anyone have any suggestions? It's quite a pretty decanter and it has some sentimental value, otherwise we wouldn't bother.

Gardengirl Posted March 30, 2011 Share Posted March 30, 2011 Steradent is meant to help. I use those little balls from Lakeland, and swish them around. http://www.lakeland.co.uk/8949/Magic-Balls Link to comment Share on other sites More sharing options...
mint Posted March 30, 2011 Share Posted March 30, 2011 Have you tried some bleach diluted? Works for most stubborn stains and afterwards swish out in several changes of clean water et voila! Link to comment Share on other sites More sharing options...

ericd Posted March 30, 2011 Share Posted March 30, 2011 Tepid water and coarse sea salt. Swirl around until the stains have gone. Link to comment Share on other sites More sharing options...

Chrissie Posted March 30, 2011 Share Posted March 30, 2011 Chop up raw potato into small chunks - smaller than you would need to go through the neck of the decanter as it will swell up. Cover with tepid water. Swirl around for a while and keep doing so for a day or so. Empty out - this is where you will see if you have chopped it small enough.....Chrissie (81) Link to comment Share on other sites More sharing options...
Manon Posted March 30, 2011 Share Posted March 30, 2011 I use dry grains of rice in water and swirl them around. You can also try some Viakal ( ? ) or similar - the stuff you use to remove limescale from taps etc. Link to comment Share on other sites More sharing options...
nomoss Posted March 30, 2011 Share Posted March 30, 2011 After 40 years it may be permanently etched by acids either in the wine or produced by stale wine (vinegar) left in the decanter. Link to comment Share on other sites More sharing options...

pachapapa Posted March 30, 2011 Share Posted March 30, 2011 Difficult to effectively agitate inside; so I use a "balais retractable" with hot diluted washing up liquid.[IMG]http://www.le-drumshop.fr/images/saico1010/561A-M.jpg[/IMG] Link to comment Share on other sites More sharing options...
allanb Posted March 31, 2011 Author Share Posted March 31, 2011 Thank you all for the suggestions. It will take some time to try them all, but if one of them works I will post the result. Link to comment Share on other sites More sharing options...
