care &amp; cleaning of reusable hygiene products Hi everyone,

I recently got reusable cotton pantyliners and got a somewhat heavy stain from my cycle on them. I've tried soaking in cold water, washing w/ dish soap or Castille soap. But there's still a stain. Any tips for how to get rid of the blood stain?

For bamboo reusable paper towels similar question. I hand wash with dish soap which helps w/ light staining. But a few of them have pretty heavy stains from taco sauce (lol). Any tips for this? Would vinegar help?
