This is probably not the place to ask this but Im really worried. My dad was doing some early morning grouting in the bathroom and then left to go out. Hrs later I forgot all about it and decided to run a bath. I didn't notice for a long while but then felt the grittiness in the bath and realised that it must be the grouting powder. How dangerous is this for me and should I be worried about it 'going' into my body? Any advice would be a help. Thanks.
