You don't say where you live (one of my pet peeves) so I'll assume you live in Texas.
Creeping Charlie is one of the most tenacious weeds around. Last year there emerged a material being used against tenacious weeds like crabgrass and nutgrass with some degree of success in the South. You might try dampening the leaves and dusting some sodium bicarbonate (baking soda) or potassium bicarbonate on it.
If that does not work, you might try household vinegar sprayed full strength on the leaves.
If that doesn't work, look for 20% vinegar to spray full strength on the leaves. This strength vinegar can only be found in garden supply places. I can get it at my local Lowes but strong vinegar is definitely not an item stocked at all Lowes. I have found it at feed stores, too. The vinegar is a foliar spray, not a soil drench. It works by drying the plant out in just a few hours of spraying. If this sort of works but doesn't dry the weed out completely, you can beef it up with a couple ounces of orange oil per gallon of vinegar. Spray during the sunniest/hottest part of the day - not in the evenings or on cloudy days.
Warning: 20% vinegar is a very strong acid. If you get it on your skin you may get burns. If you get it in your eyes, you will be blinded for months or longer. Consider wearing a full face mask when handling it.
