Ok, first things first, Thanks again for the assistance guys, the damp cloth worked a treat!
I'll let it dry properly overnight, and give it one more wipe over tomorrow, but the majority of the timbermate has gone.
I sanded back everything else to 240grit, and I'm really happy with how it is all going so far.
I should have some nice figuring on the back looking at how this is going so far.
I'll go to 320, or maybe 400, and then go with the black stain.
