Advice on caring for antique glass from the British Antique Dealers' Association.
Antique glass decanters
Antique glass decanters can be prone to staining.
Acids in wines can cause milky stains which require professional buffing to remove.
To avoid staining, always ensure your decanters are thoroughly dried after use.
Chips and repairs
Minor chips on wine glasses can only be eliminated by reduction of the glass.
As a result, this practice is restricted to glasses of comparatively low value.
Chips on important period glasses can often be filled with a resin which renders the damage inconspicuous.
In the event of a break, avoid touching broken edges as fingerprint residue can hamper the rebonding process.
In all instances, it pays to seek professional help from a specialist dealer.
Cleaning antique glass
To reduce the risk of accidents, remove any items of jewellery before cleaning.
BADA recommend using a plastic bowl to wash antique glass, rather than a metal or ceramic sink.
If you have to use a sink, make sure the tap spout is turned 90 degrees from the sink to avoid accidental contact.
Virtually all antique glass should be washed in water as hot as the hand will stand, with the addition of a little washing up liquid.
Rinse in water of the same temperature and dry with lint-free cotton cloth, while the glass is hot.
The heat of the glass will do most of the drying.
