Burettes need help cleaning

Hi folks, I have two old type Burettes, that I do not seem to be able to clean. They have grease marks on the in side of the Burettes. I have tried warm soapy water, HCL diluted. Perhaps I should give up and throw them away.
They would be great as spare's.
Regards

Hi
Try a conc. solution of Pyroneg, its fairly agressive detergent, and soak for a day or too. I still like Chromic Acid for such things, but that a no no these days.

Hi All,
I would intend to use a solution of Oxalic Acid and keep it in for at least a week.
If this does not work try using Conc. Sulfuric and keep this acid in the burettes for a week also.
It is certainly worth a try.
Hope this helps,
Robb.....

Hi Pommie,
Did you know you can buy burette brushes? I got mine from Q Stores some time ago now so I'm not sure if they still keep them.
If you can't find one I'll send you one of mine.
Cheers

Hi Judy, The acetone worked very well, had forgotten about brushes. Good idea.
Thank you Sue
