    Good evening!

    I have just spent the past 90 minutes cleaning my re- conditioned Corny kegs using 10 x 5ml teaspoons of TSP in 19litres of warm water. The solution was left for an hour with the occasional vigorous swirling! After a good rinse through I still have some black deposits left on the kitchen towel when wiping dry the inside.

    This may be a simple (aka stupid!) question but is it ok to proceed and fill the Corny once I’ve sterilised it with Starsan or should I clean again?? What actually is the black stuff??

    Thanks

    It's sanitising with star san and it needs to be clean first otherwise it's pointless

    Hi @SkyBlue
    I always use an oxi-type cleaner like PBW or Wizz Oxi - it eats away all types of crud.
    What's TSP?

    Trisodium Phosphate. I was told it was the ‘dog’s dangly bit’ when it came to cleanining stainless steel but clearly not. I will clean again and hopefully that will do the trick.

    Hi!
    I remove the lid to deep clean a keg.
    I always use a bucket: add 10 or 11 litres of cleaning solution and leave in the keg for about 10 minutes. Put the bucket over the keg and invert. Leave for a further 10 minutes and rinse.

    TSP isn't that for cuts?

    Lol, well I'm no expert and certainly can't say for sure but if that's safe to put on human lacerations I can't see it being powerful enough to clean stubborn stains

    Strip it, every part, every "O" ring every popet, get your hand in there with a scourer and give it a good scrub. Don't forget to wash through the beer out tube.

    When it's clean reassemble spraying Starsan as you go then flush with Starsan drain and use.

    TSP is a powerful degreaser used for cleaning new stainless steel to get rid of grease left over from manufacturing. I can't imagine what the black stuff is that you're seeing in a reconditioned keg but Barkeepers Friend works wonders on my kit.
