Ceramic tiles are a great invention. They are not only durable, but can withstand high temperatures without burning or emitting toxic fumes, hence are suitable for kitchens and fireplaces.
They are also moisture resistant and can be used for wet areas like sinks and bathrooms.
For the bathroom floors, slip proof tiles with grooves are preferable because they are not slippery compared to the ordinary tiles.
Due to their durability and resistance to wear, tiles can withstand huge human foot traffic in high traffic hallways and corridors. However, they require a skilled mason to avoid breakages at the corners and edges.
The beauty of tiles is that they come in a variety of colours, shapes and sizes to suit every creative designer’s imagination and can therefore blend in with any dÈcor. Ceramic tiles are hygienic because they are easy to clean. One just needs to sweep and then wipe with water. An occasional vacuum cleaning or scrubbing with a scotch scrubber will keep them shining.
Method
However, when neglected, tiles can sometimes stain and look unsightly. To remove the stains, hydrochloric acid, otherwise known as muriatic acid, can be used as a last resort.
You will need the following items to safely remove stains: Rubber gloves, filter mask, hydrochloric acid (muriatic acid available at hardware shops), protective clothing, paint brush, stiff scrubbing brush, plastic bucket and floor cloth/duster.
• Put on the protective clothing, rubber gloves and filter mask and open windows to ventilate the room you are working in.
• Pour five litres of water into the bucket to prevent the acid reacting on the plastic.
• Use a plastic or glass measuring cup to measure one cup of muriatic acid and gently pour into the water. Avoid using a metal measuring cup as it can react to the acid and cause fizzing or emission off dangerous fumes.
• Use the paintbrush to apply the acid/water mixture onto the stained tiles and let it sit for three to five minutes.
• Rinse the tiles using plenty of water.
• Scrub the tiles using the stiff brush to remove the stains, working in back and forth motions.
• Rinse off again to ensure all the acid residue has come off and wipe dry with the floor cloth.
Caution
• Cleaning tiles with acid should be used as a last resort rather than a daily, weekly or monthly routine.
• Wear protective gear when using acid.
• Keep children out of the area being cleaned and keep acid clearly labelled.
• Pouring water into the muriatic acid could cause a splash of the acid as it sprays out of the bucket.
• Should acid accidentally pour on another surface or item other than the tile, immediately pour bicarbonate of soda to neutralise it.
