What is the best stuff to get rid of creeping charlie weeds

I don't know what creeping Charlie is. Could you possibly send a picture?

Use only on lawns.

I also suffered with Creeping Charlie! At one point, two thirds of my lawn was taken over. I tried everything under the sun. I finally tried Spectracide Weed and Feed. I mixed a much stronger solution than the instructions said. Used a handheld sprayer and really wet the "lawn" down with no rain scheduled for the next few days. Killed the Charlie and he lawn came back stronger than ever. I still get some Charlie coming back every so often, so I pull out what I can and spot spray it along with other weeds as general maintenance.

As a master gardner, I would advise ALWAYS follow the directions, and it is very dangerous to "mix a much stronger solution". Not to wise, and actually depending on the product LABEL, ILLEGAL

Creeping charlie is a weed that can take over your lawn. It has small jagged edged leaves and sends out runners everywhere. The only thing I have done that gets rid of it is to physically pull it up. Use a rake to get under the running stems and go back to the root and pull. As far as I know there is nothing that is legal to use in my part of the world.

I use tea kettles full of boiling water.
