Sorry to butt in here, but I don't think any 'antiqueing' was done by Harbour Lights after the first couple of years.

Certainly not on 1995 Big Bay pieces. If they have that 'yellowing' or 'spattered' look, the discoloring is from smoke and/or plain old dirt (maybe grease).

There's not much you can do to clean a Harbour Lights. A simply lens cleaning brush with a blower bulb would help to dust it off.

Long time Collector Forum members know that there have been cleaning experiments done with a Kitchenaid Superba dishwasher model by a 'collector nut.'

I can't recommend the 'canned air' kind of blowers, especially on older pieces where the paint may flake off.
