“How long does it take to detox from anesthesia?”

Very difficult to answer specifically. It depends on what medications you received, your overall metabolism for medications ie. is your liver and kidney function normal? In general relatively healthy patients will metabolize the medicines quickly and “detox” by normal elimination in a day or so. The extreme elderly or patients with kidney and/or liver disease may take a little longer. Depending on the surgery, recovery from the stress manifesting as getting easily fatigued, the feeling of not feeling being 100% can linger. This is not due to the lingering effects from anesthesia. Most often the hangover feeling is dependent on the amount of opioids for pain one is taking.

If your goal is to rid your body of all anesthetic substances administered, then the only thing you can do is wait about 7-10 days and none will remain.

There is no considerable "toxicity" with anesthesia. So, there is no go-to detox regimen. Drinking as much water as possible can help to clear medications through the liver and kidneys.
