Kveik Contamination - Is It An Issue?

[Protos]

Gentlemen, I'm planning to brew my first batch with Lallemand's Voss Kveik (actually my 90th batch).
My question is: do Kveik fermentations require same extra contamination precautions as with Diastaticus yeasts? I was a non-believer in Diastaticus contamination and thought the standard cleaning protocol (rinse with water after use > soak for a half an hour in Chlorinol/Iodophor/StarSan solution before use) between batches would be ok till it badly affected some of my batches, after which I have separate brewing equipment for Diastaticus and Non-Diastaticus fermentations.

What's your experience, is it safer to have a separate brewing set for Kveik? Or standard cleaning protocols (like those between English/American yeasts batches) will be fine?

I haven't heard of anyone having issues with Kveik strains being persistent in brewing equipment. OTOH, most people also have no issues with diastaticus strains.

Regarding your standard cleaning protocol... "rinse with water after use > soak for a half an hour in Chlorinol/Iodophor/StarSan solution before use "

... are you really not using any type of cleaner (other than plain water)? That could be an issue there. As someone once said, "you can't sanitize dirty."

Thank you!

Yes, I used just plain water to rinse the equipment after my brewday. It didn't look like any gunk accumulated in my equipment so I didn't use any cleaners. Before brewing a new batch I sanitise same equipment in Chlorinol or Iodophore or StarSan solution for half an hour or more. Still, I got a Diastaticus infection from my Saison batches. I think now the culprit was an invisible biofilm which I would have to scrab away, not just soak in sanitizer. So now am a bit vary about Kveik. What you're saying sounds good.
