Follow these tips for effective and intensive care for bathroom tiles:

For dark stains, use a brush with soft bristles. Apply some soap or detergent on the stains and leave it for some time. After that, you can scrub it with the brush.

For mildew, apply chlorine bleach mixed with water using a soft bristle brush.

If the stains are extremely tough to remove, like those of ink, apply chlorine bleach directly on stains.

10% sodium carbonate, which is found in soda ash and washing soda, is helpful in the removal of grease from the bathroom tiles.

If there is rust, you can use a solution of 5%  HCl but make sure you do not use it on glazed tiles.

Cigarette burns can be removed by scrubbing the surface with steel wool.

Nail paint can be removed from the tiles by wiping the surface with a cloth soaked in nail paint remover or ordinary acetone.
