How long should I let the grout dry before trying to wipe the tiles off?
For the initial cleaning, wipe the tiles off immediately after you have removed excess grout by drawing float diagonally across tiles at a 45 degree angle and then 90 degree angle (at a diagonal to the grout joints). Simply wring out a damp sponge and slowly wipe tiles using a circularmotion, exercising caution not to press too hard with the sponge.For final haze removal, allowgrout to cure for 24 hours. Cheesecloth works nicely for this.
