Please help! Old carpet stains what spot stain remover works?

[PreHeatedOven]

As above really.
Our rented house has some grey carpet stains I want to remove, I can't clean the whole carpet I need a spot stain remover. Which one works on old stains?

Big fan of HG, which I got at B&Q

I've found White Wizard great for carpet stains.

I can't seem to be able to buy white wizard on Lakeland. Am I being stupid? Help lil please!

I think it is because it has been discontinued.

They seem to sell it here.

I don't know this company though.

sorry - I know I got mine from Lakeland but it was a while back and I just found the link. Looks like lakeland now have their own version but not tried that to know. Rat has found you another place to buy it!
