Generally I would think of stainless steel as “stain-resistant”, not “stainproof”.
I used stainless steel equipment in the darkroom and I always saw some amount of staining or corrosion. It will even rust, under certain conditions.
- apercu 3y agoDarkroom chemicals versus natural environment? (Though maybe it's pollution or trace elements in organic materials causing the rust / pitting on the CT?).
- klodolph 3y agoDarkroom chemicals have varying pH, both acid and alkaline, there’s various salts involved, and there’s a decent amount of metal-on-metal contact in development tanks (you load the film onto a metal reel, and the metal reel goes into a metal tank, and they rub against each other).
- apercu 3y agoFair, 90% of my darkroom experience was a stat cam and we used plastic tubs and rubber(ized?) rollers. They always stained but since I wasn't using metal...
- acdha 3y agoThat’s the right way to think about it - it comes in different grades based on the expected level of exposure to things like strong acids or bases but it’s not magic. You can especially see this in appliances where stainless steel was marketed as a premium product but the cheaper lines (or cheaply-made / expensively-marketed) are much less durable than the painted metal they used to use.
