As I have said on here before, many years ago before food grade plastic FVs and certainly shiny SS FVs were available I used an orange plastic dustbin to ferment in. And I wasn't too fussy then about how I cleaned it and did used to scratch off dried up bits of gunk from the sides. And as far as I can remember I never had one 'infected' brew. Although my cleaning and sanitising regime for FVs is more rigorous nowadays, including the use of boiling water, I don't get concerned about the odd scratch or two on my plastic FVs and wouldn't contemplate replacing them for the sake of it. And although shiny is nice it's also expensive. You can, looking at the costs quoted above, buy upwards of 10 plastic FVs for the price of one SS FV, and at the end of the day what comes out of them at the end of the fermentation is exactly the same, although I'll warrant someone on here will tell me it isn't :whistle:
