Cleaning "rings" in bottles

[JamesF]

I have some bottles I was given that I think have been left (opened) outdoors for some time. Over time I guess they've collected a little rain which has evaporated leaving a "ring" around the inside of the bottle. This doesn't seem to want to shift using oxyclean and a bottle brush. I'd prefer not to stick them in the recycling, so I'm thinking of giving them a soak in a solution of citric acid to see if that will clean them.

Does that sound like it should work, or should I try something else, or is it really far less pain just to bin them and move on?

It should but If it doesn't they should probably be consigned to the recycling bin.

Good luck

[JamesF]

Yes, if I can't get them clean then I certainly won't be putting beer in them.

I picked up some bottles from a local pub and used half a teaspoon of sodium percarbonate per bottle and hot water (>60C) for half an hour. Absolutely clean inside.

[JamesF]

That might be worth a try too then as it's probably a higher concentration (and higher temperature) than I'd normally use.

Some months ago I cleared out a pub cellar and collected 50 old bottles which I dumped into a bath of bleach and left for 10 days cleaned perfect

Does that mean you didn't bath for 10 days. Phewwwww!

[JamesF]

I've not had a bath for years. It's very peaceful here
