Dog wee smell

[JamInMyWellies]

Our dog has been trained to wee on an area of patio round the corner from our house.

The problem is how do I get rid of the smell. I have tried jeyes fluid just makes the garden smell like a public toilet, zoflora does nothing. Today I emptied 2 tubs of bicarb of soda and scrubbed but I can still smell wee.

Does anyone have any magic solutions that will remove the smell from the garden?

Any of the morning good houskeeping ladies know what I can use?

Just googled dog wee remover and found this product that can be used outside.

Thanks dexter have just ordered some.

Wash with a 10% bio washing powder & water solution, let it dry completely, then spray with meth spirits(spelling?) (the purple stuff), let dry again.

The dog won't use the spot to urinate again, as all traces of the scent will be gone.
