For homemade hand sanitizer it depends on what ingredients you use.
Items should be submerged in sanitizer for at least 1 minute to ensure proper disinfection.
By using a clean sanitizer
As long as the hand sanitizer uses Ethyl Alcohol (Ethanol), not Isopropyl alcohol, then yes. Most do, like Purell, 62% Ethanol.
One way to tell the potency of hand sanitizer is whether the liquid still contains bubbles. It should, per Purell customer service.
Technically, since it's a hand sanitizer and sanitizer means "to make sanitary, as by cleaning or disinfecting" then obviously it's the dirt get cleaned and not the sanitizer get dirty.

Hand sanitizer will not get rid of warts.
Purell hand sanitizer, like other alcohol-based hand sanitizers, has a shelf life of about 2 to 3 years when stored properly. After this time, its effectiveness may diminish, especially if it has been exposed to heat or sunlight. It's important to check the expiration date on the packaging for optimal efficacy. If the sanitizer shows any changes in consistency or color, it’s best to discard it.
