10%bleach/water how long?

how long should i leave tank items i am cleaning in 10% bleach and water solution?..

oh and hi this is my frist post! lol i have a jungle carpet python a couple months old and will be getting my first bp at the end of the month!

Whenever I use Bleach, its always a 10 minute contact time, but I have read Bleach really needs 30 minutes.

I dont use it anymore, I use Chlorhexidine and Trifectant, both which get a 10 minute contact time.

I was using Chlorohexadine until I read it didn't kill many viruses. I switched to bleach and then read a few posts that vinegar/water (50/50) was JUST as effective as bleach and much much safer. I spray my tubs down with a good soaking of 50/50 vinegar-water, wipe the tub with papertowels, spray the tub with water, wipe out all the moisture with paper towels, and put my BP's back in.
