Adam,

The reason they turned gray is due to the acid in the polishing powders,
black grout will normally turn a lighter color anytime you polish it with a
polishing powder.

Be sure to clean the grout line well during the polishing process.

You will probably need to dye the grout line. Suggest using Grout Perfect

This is sanded grout and  I cleaned very well but it became gray when dried.
What do you think about color enhancer sealer?

Hey Adam,

Just some suggestions;
1. Don't let the polishing powder dry on the grout.
2. May have to color seal the grout in the end. Is it sanded or
unsanded grout?

Respectfully,
