Hi ,I've been asked to clean a cooker which has had Mr Muscle oven cleaner sprayed all over it inside and out which has then been left for god knows how long !
My question is does anybody know how to remove the white residue that said product leaves behind ??
I've tried various things but to no avail , there still remains traces of the residue and no matter what I have tried when the surfaces dry out there is still staining
Any help would be greatly appreciated
