Evergreen 4in1 ruined my decking

[Booty1978]

Hi
I have recently put down some decking! I then used evergreen 4 in 1 on my lawn! I then walked across the decking a few times & when I woke this morning I found black footprints marks on the decking! I tried washing off & doesn't seem to work?! Any advice really appreciated?!

If i recall right a lot of those green up things contain copper sulphate,don't know how to remove but just save some pee and put it on the grass with a watering can,loads of nitrogen and free!

Evergreen also ruins lawns

Sorry Booty, but don't think you'll be getting that off

Just do the same again and create a pattern.

Can you get a sample of decking to experiment with? Oxalic acid can be used to remove stain and might work. Be aware that it is toxic, and burns, so if you use it, goggles and gloves are advised. It is dissolved in water, and when I used it the table top warped. Oops. I was able to remove the warp, but you need to apply with care ie don't soak large areas for a long tome, apply it locally only.

I think he might have sorted it by now
