Answer 1

The best way is to use dilute phosphoric acid. You simply paint it on the tiles and watch the colour change.
It converts the red rust oxides into soluble greyish phosphates which wash away with fresh water.
You can buy proprietary mixes of this in most building supply shops.

Answer 2

call the local outlet that did the floor.
do not apply any chemical and ruin the floor.
the dealer will be happy to help you
