fixer residues??

[pergorm]

Hello!!

This may be a stupid question, but here it is anyway:
Does anybody know how to clean old fixer residues (black!) off the insides of plastic bottles and containers???. I can not reach it with a brush...
What are they??? Silver ??

Regards

Yes it is probably silver, and no there's no way to remove it easily without some sort of scrubbing. But it doesn't affect anything.

Actual fixer residue is white.

If your residue is black it's probably metallic silver, as Cyrus said.

Both are quite difficult to remove.
