How to clean bathroom tiles at home 1) Dip a damp sponge into a bowl of pure baking soda and use this to scrub down tiles, grout and other bathroom and kitchen surfaces. Rinse thoroughly or wipe well with warm water. 2)Mix equal parts distilled white vinegar and water in a bottle and spray it generously onto tiled surfaces. Allow to sit for a few minutes before scrubbing with a brush or sponge. Extra tough stains may require the combined action of baking soda and vinegar. 3) use lemon juice,It has the exact same action when it comes to tiles – it is an effective stain remover. Like vinegar, fresh lemon juice is acidic in nature, It works best when combined with baking soda. 4)Mix hydrogen peroxide with white flour to create a thick paste. Apply this to the tiles and cover with plastic wrap. Allow to work its magic overnight, before rinsing well with cold water.
