Renovated pool with plaster on grout

We are in the final stages of renovating our pool. We had the tile, grout and plaster replaced. Our contractor doesn't always show up and there is some language barrier with his workers.
We chose gray grout and when they plastered the pool the plaster is now covering the grout in many places. We would like to wrap this project up with the weather getting nicer.
How can we (the contractor) remove the plaster from the grout without damaging the grout?
Thanks for any suggestions.

Welcome to TFP.

If it was me I would not worry about it. No one enjoying your pool will notice it except for you. There is no easy way of doing it without also removing some grout.

That said you can use acid to soften the plaster but it will soften the grout also and you may hit other areas of plaster.

Or take some grout and apply a skim coat over the plaster.

Neither of those may look better long term then the way it is now.

To do it properly, you need to grind out the plaster and old grout and regrout. You may be able to get away with just grinding down the plaster overspray.
