I sprayed brick acid on a bad stain on the gable harling caused by a leak from the boiler in the loft. I didn't rinse quickly enough and it's left a light brown stain down the light colour harling. It's like it's burned the mortar

Cheers, I actually sprayed a bad leak from the boiler in the loft with brick acid and did not rinse quickly enough and it's burned the light colour harling a shade of light brown.

What chemical cleaner can get rid off or even lighten brick acid stains on gable harling.
