Has anyone seen this before? How can the stains be removed? New Install of smoked lueders at the start of May. Pool was finished at end of June. Stains are on both the pool coping and on border and steps located 15’ from pool. Stones have been sanded and cleaned at different times and stains remain. Hot gun tool was used to pull moisture out but still no luck. If anyone knows of a professional who can educate me on the corrective action for this please let me know. Thank you!
I have not seen that before. I would be very upset if that were in my yard 
I would be asking for new and NOT using the same kind.
