<human>:  How do I clean my bathroom tile grout?
<bot>: To clean your bathroom tile grout, you will need a clean cloth, a bucket, some mild detergent and a brush. Start by mixing the detergent and warm water into the bucket. Dip your cloth into the mixture and wring it out until it's just damp. Begin cleaning the tile grout with the damp cloth, rubbing in small circular motions. Next, use the brush to scrub any stubborn grime. Finally, use a dry cloth to dry and polish the grout.
