Cheaper bladder cleaning options

[Alphitomancy]

Hi, I've run out of my last cleaning tabs. What are good suggestions that are cheaper than the hydrapak/camelbak tabs? Or just an old vinegar water solution etc?

Cheers

Denture cleaning tablets work well, and are cheap

Soap, water + narrow brush
I've also soaked the tube and bite valve in hydrogen peroxide overnight many times without damage.
