You know, I refuse to give up some of those things. When I lived near a Costco (and some fancy groceries that are big into sampling), going out and trying new things was a simple thing that gave me a lot of pleasure.
BUT... I decided that I would stick to the spirit of free samples. They put them out to let you try something new that you might decide to buy. So if I've tried it before, or if there's no way I would ever buy the product, I don't sample it. If I only sample things that are new, and if I keep a mental count and do my best to record and track what I ate, it doesn't seem to hurt my progress overall. (I'm 400 miles away from my Costco and my specialty groceries now, so it's moot, but I'll do the same when I move back to civilization in six months or so.)
You can apply the same idea to "sampling" things at home. If it's not new, you don't need a bite. You already know what it tastes like. It's just a matter of figuring out how to remind yourself of that. The mouthwash idea would work for meals. As for snacks and nibbles after or between meals, sometimes just making it a new rule that food always gets put away immediately will work, and give you a tidier kitchen to boot. Train the family to serve themselves one serving, put the package away, and only get it out if they're going to have another serving.
