good brush for 2L flask

[kappclark]

I am looking for a good brush for my 2L flask - any suggestions ?

I use a bottle brush if brushing becomes necessary. They wire can be bent to form an angle.
Unscented Oxyclean will usually take care of spots that don't readily rinse out.

I use my carboy brush..

Carboy brush, kitchen sink brush or dishwasher. It's not that difficult to clean like any other dish in the cupboard

If you get in a pinch you can always clean it with ice and salt. A long time ago when I used to work in a restaurant, we used to clean all of our coffee pots this way - fill up about 1/4 full with ice cubes and a healthy dose of salt. Let sit for a few minutes to get an ice-salt slurry, then swirl around in the air for a few minutes. They always come out crystal clean and shiny.

I just picked up a 5 liter Pyrex erlenmeyer flask for 10 EUR, hell of a deal. I'll be using the above technique tomorrow to clean it since it appears that somebody has been using it as a flower pot or something.

I also bought a wine bottle brush and bent it like a carboy brush.

I couldn't get the carboy brush to fit into my 2L flask.
