So I have a new build pool. The coping is darker grey concrete cantilever coping. There is dirt embedded into the broom finish of the coping and I’m trying to find a way to clean it up. My dirt is heavily clay. I know it should be the builder to clean it, but they are playing the blame game now. They say it should be the concrete subcontractor, then the tile subcontractor and it’s not the PB’s responsibility. I have tried just hosing it down, but it is not effective. Can I use muriatic acid, dilute it and spray it on then hose it off? It shouldn’t be an issue just hosing into the pool considering we pour it into the pool anyways right. Tried power washing but that was barely effective also. Open to suggestions. Thanks.

I don‘t know what your expectations are for the look you want to get your coping to.
They are playing the blame game because it cannot simply be cleaned.
Pour acid on dirt and it doesn’t do much of anything. Acid will etch the concrete more then dissolve any dirt. You tried power washing. I would give things a year or two and see how your coping weathers in and how it looks.

Unless you contracted with the concrete guy yourself, the PB is the GC and he should do whatever it takes to fix the problem.
