Like I said, they will probably say I should have started with a dilluted mixture first and then go up in strength as opposed to using it neat from the off. 
Tis ok, I had to learn the hard way, changed the thread title to reflect that. 
  
I don't think the bottle mentions using it neat ?!? 
I think the very least you should be using it was 1:1 ( ie 50% diluted ?!? ). I always use one 1:3 and have never had any problems ( my wheels never get dirty enough to warrant using it any stronger ). 
Don't have the bottle in front of me so I'm probably wrong !
