I carry a spray bottle of bleach/water solution and spray all connections both when connecting and disconnecting for this reason.
The YouTube video is great, other than the technique of leaving the gray water valve open, as discussed in many threads. I strongly advocate both wand and the installed tank rinse system, on occasion. Only the wand can get to all areas of the tank.
Please, as a matter of health and safety, avoid leaving either slide valve open, unattended. People do it, but the practice is risky.
To piggyback Rick's excellent advice, if you push a full gray tank through the hose after draining the black water and closing its slide (a few moments AFTER opening the gray, to clear the slideway), the hose need not be rinsed. Simply inchworm it to the dump so that it is drained, disconnect at the rig and cap that end, compress the hose with the rig-end held aloft, disconnect and cap at the dump end, and store. It's already cleaned by soapy (and probably warm) gray water.
That simple courtesy renders moot the whole contamination argument.
But, always spray the freshwater hose bib with bleach prior to hookup, assume that the Clampetts were using the site before you and spattered everything with hose rinsewater.
