How to clean a new tile floor with single component grout without causing damage to the grout
The company says that you do not need to seal it but some users say that it will stain. 

So i would use a good sealer on it, wait the time specified on the instructions and then use a mild detergent like TSP and an abrasive pad. Clean with clean warm water and sponge.

(To be fair it is an "Advanced acrylic plus silicone resin formulation" so i do not know how well the sealer will penetrate it.) 

Wait a week and seal again and then you should be good to clean it when needed. 

It is tile and should not need harsh or extra strong chemical cleaners. Mild soapy water will be just fine.
