It seems a bit of excess cement or grout have mixed with water and stained my bathroom tiles. Tried soaking it / rubbing it with cleaning vinegar but to no avail.
Ideas?

Use a commercial grout cleaning product or a 50/50 mixture of white vinegar and water. Spray the solution and let it sit for a few minutes then scrub with a sponge or brush. Repeat until the stains are removed. It may take multiple tries.
In the to-do section of the care instructions you posted, it suggests "Use an all-purpose, non-oil based household or commercial cleaner." OR, it says, you can use vinegar/water.
I think you are over-analyzing. The normal floor mopping solutions like Pine-Sol or a Swiffer will work fine. Just don't use anything abrasive that will scratch the tile or an aggressive bathroom "tile/grout cleaner" that is meant to bleach and renew grout that is stained.
If you're concerned about a particular cleaner, you could always test a small section that is out of sight. You can also apply a "grout sealer" solution over the grout lines. This is tedious, but can help slow down staining of the grout.
