This weed will not die! What is it?

I'm pleased that it worked for you :thumb:.

Of course, using any of these things is not allowed (even wallpaper paste or detergent ) unless it has been licensed so I'm sure you won't use them again :wink: :wink:

On a safety note - the acid you have can be very dangerous and was probably supplied in a molded polystyrene box inside a cardboard box (if it wasn't, then it should have been). Keep it in the them. If you haven't got them that way then you should keep it packed away where it can't accidentally fall over and break.

You can use the acid, carefully, to make your own pickling vinegar - which is what I do. Of course, I would never try and use it as a weedkiller :wink: :wink: :hehe:
