Whats the best cleanig product???????

Hi, I am due for a clean up soon with my RDWC system and i am wondering what is the best chemical to use to clean the container, drains, water pump, air lines, air stones & ect, ect?? I have seen a few threads on 35% & 50% H2O2 but the threads mainly talk about using it in the systems not as a final scrub down. Using H2O2 isn't a problem but could someone tell me the amount to use for those 2 diff strength or maybe recomend a better chemical?????
Thanks all........

I don't use any chemicals in my growing medium. I get by with a pump up sprayer and a broom brush to keep everything reasonably clean.

I simply replace airlines and old airstones.
