Just rinse, rinse, and rinse again... Then rinse it in some vinegar and rinse, rinse and rinse again... Have fun lol I did this when I had a dropsy breakout in 4 of my breeder tanks...
HTH
my 20G used to house 2 comets and 2 loaches (stupid thing, it was before i knew anything....) and they lived nicely for 6 months. then one day a mysterious disease just took a hold and not even doses of melafix or pimafix and water changes would work. eventually they all died within a week. i threw away the plants and removed the decor and substrate.
they were then placed in a bin and rinsed repeatedly. then i got a capful of bleach and washed both my tank and soaked everything for about 2 or 3 days. overkill since bleach pretty much kills anything instantly but i had to be sure. power filter was also cycled with the bleach water during all of this.
everything was then drained and soaked in tap water for another few days and a lot of rinsing and drying. finally i was sure everything was clean so i set up the tank again, added a slightly larger than usual dose of water conditioner to get rid of any chlorine and my tank was pretty much clean.
As above bleach/chlorine will kill just about anything. Also it tends to evaporate and not leave a residue. Just make sure you rinse everything well. Don't use any 'soap' type things. Another option is heat, a sustained high temperature will also kill just about everything. You can boil small amounts of gravel at a time. Even hot water out of the tap is better than nothing.
