I have had good results in controlling moss in my lawn using vinegar. Don't know if it would work on creeping charlie. I got the following from typing in creeping charlie in to google.com
If you catch it early, you may be able to control creeping charlie by pulling it out. If it becomes thick, you can use a special tool called a thatching rake. This helps to comb through the grass, pulling much of the viny weed out. It doesn't eliminate it, but may keep it in check. (Some grass will be pulled up in the process.)
Using this tool is more physically demanding than fall leaf raking, however. It provides a strenuous workout, and may be more laborious than what you wish to undertake. This operation thatches the lawn and cuts into the soil. Afterwards, you can work in some shade-tolerant grass seed to replace the creeping charlie. The best time to do this is between mid-August and mid-September. Choose a time when the weather is beginning to feel cooler.
You may control creeping charlie chemically by applying a herbicide containing 2,4-D and MCPP as its active ingredients. The herbicide will damage or possibly kill any woody or broad-leafed vegetation that comes in contact with the spray, so it must be used with caution.
The best time to spray is in autumn, once temperatures have cooled to the 60's or 70's, with no rain forecast for 48 hours. This spray program may be repeated every ten to fourteen days as long as the weather is cooperative.
A combination of 2,4-D, MCPP and dicamba may be used under some circumstances. The three together work more effectively than 2,4-D and MCPP but one reason for that extra effectiveness is dicamba's ability to be absorbed through the roots as well as through leaves. Since creeping charlie frequently grows in the shade of trees and shrubs, this combination of ingredients must be used with caution, spraying only enough to wet the leaves, not soaking the ground. This combination will prove more effective and pose less danger to desirable plants when it is used in early fall rather than spring.
If you have areas with more creeping charlie than lawn, you may wish to start over. Strip it off with a sod lifter (a hand tool), a sod cutter (a power tool) or apply glyphosate (a non-selective herbicide, sold as Roundup) to kill the entire area. Then you can seed or sod.
Where creeping charlie persists after years of repeated attempts to control it, you may want to consider killing it and replacing it with shade-tolerant ground cover plants or decorative mulch.
If you are interested in trying to eliminate creeping charlie with a borax application, see Yard & Garden Brief H519B, Using Borax to Control Creeping Charlie.
