Have done a search but cannot seem to find what I need.
I have a number of trays and storage bottles that have become stained with use and would like to clean them. Normal washing ie. soap and warm water has had little effect.
The stains are as follow:-
1 silver stains on trays used for developing.
2 brown stain on tray used for Selinium toneing. [spots here and there not all over]
3 blue stain on bottles used to store mixed Ferricyanide/Potasiumbromide bleach. [ forgot about it and it exhausted its self in the bottle]
Please does anyone know of a cleaning agent or recipie for one that I could mix up from basic chemicals suitable to deal with the above stains.
I have tried Domestos bleach but it had little efect apart from makeing the darkroom stink.
Thanks in advance, regards Paul.
ps. sorry realised I did not tell you all articles are plastic and JOBO manufacture.
