Tried and Failed to Remove Old Paint from Fireplace

Hello-
Our house has a brick fireplace painted white that we wanted to strip
and leave it a natural brick. I used a citrus based stripper, and this
got off a lot of paint, but not enough. The paint wouldn't all come
off, especially in the grout, even with a lot of scrubbing. So I gave
up. We have decided we will just paint over it with a color we like.
The problem is there is still some residue from the citrus stripper. I
have used mineral spirits to remove some of it, but its still kind of a
mess. How can I either remove the rest of the stripper so I can
repaint, or otherwise prep it to be painted so the stripper underneath
doesn't compromise the paint on top? Any help is much appreciated.

I thought you use water to clean up a citrus "safe" stripper. Mineral
spirits might just push it around. Did you follow the instructions for
cleanup and neutralization. Denatured alcohol would be a better degreaser
after soapy water.

it is not uncommon to need several applications of a stripper to clean a
porous surface like brick and stone. But sometimes it comes down to
sandblasting.
