Stain testing on polished marble


After polishing marble, using the grinding and honing method, a sealer can be applied to protect the Marble. Marble is a soft stone resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. Given the nature of the stone, it can react with substances that fall on it, causing a chemical reaction, which can stain the Marble. Sealers help to protect the Marble against the same.
There are several sealers available in the market. Before a applying a sealer, one should test a small area with different sealers to check which one is best absorbed by the stone. Since Marble is cut from a natural rock, chemical composition is different in every stone, hence sealers can react differently on different types of Marble.
R&D is important on sealers. One such testing happening at our office on Saturday using DuPont sealer on which has been spilled tea, coffee, water, ketchup and mustard.

Your mirrors will look brand new if you sprinkle a mixture of vinegar and water on old newspaper and use it to scrub your mirrors.


Close the water faucet/tap to the WC and flush to drain all the water. Pour a bottle of vinegar into the WC tank, squeeze a lemon if desired. Scrub the insides of the tank with a brush. Let the vinegar sit in the tank and bowl for as long as possible (overnight or a couple of hours). Thereafter, open the water faucet/tap to the WC and flush twice.


Grout in the bathroom is porous and could lead to the growth of bacteria. Mix water and bleach in the ratio of 10:1. Dip an old toothbrush in the mixture and scrub the grout to remove any mildew. Rinse well once completed.

Sink / Wash Basin

To clean the drain of your sink, pour ½ cup baking soda followed by ½ cup of vinegar down the drain. Let it stand for a few minutes, then pour boiling hot water to clear the drain. The sink can be scrubbed with a mixture of vinegar and water. Sprinkle vinegar on a microfiber cloth to polish bathroom fittings.

Shower Cubicle

Hard water deposits on shower cubicle can be hard to remove if you don’t do a regular deep clean. Prepare a paste of vinegar and baking soda. Apply the paste to the hard water stains using a scrubbing sponge or toothbrush in a circular motion. Leave the paste for 15 minutes. Remove the paste with a damp cloth. If the stain persists, spray a mixture of vinegar and water on the glass and wipe off with newspaper.

Fire safety in public places


Last month’s terrible fire that ripped through two upscale restaurants in Mumbai’s Kamala Mills has come as a shocking wake up call. Fourteen people lost their lives. Most were young people in their twenties and thirties whose bodies were found piled up in the toilet, where they retreated hoping to escape the fire. This could have been any of us, who visit restaurants, bars, clubs to enjoy a night out!!

To prevent such incidents repeating themselves, we have compiled a few useful fire safety tips to keep in mind when enjoying yourselves at a public place.

  • Know your exits. Wherever you are, you must take a moment to mentally note where the different exits are. These signs are usually lit up and easy to find. Most of the people who died in the Kamal Mills fire tragedy had trapped themselves in an un-ventilated bathroom with no escape and they suffocation to death.
  • Be aware of location of fire extinguisher and / or water hose. Observe as if your life depends on it. It does.
  • Our fire safety norms are followed rarely in public places. Therefore, avoid shows where the performers use fire as a prop.
  • Heat and therefore smoke rises, staying low, as low as you can get, helps. If there is smoke in the room it is advisable to crawl on your belly. Almost all deaths from fire arise from suffocation caused by smoke and not from the actual fire.
  • If you are trapped in a room with no exit the best thing you can do is stay low to the ground, breathe through a cloth or clothing over your mouth and nose, and make some kind of a signal to the outside (example hanging any garment, even a tablecloth out of a window). If windows are locked, break them and try to signal for help.

We urge you to take a few minutes to be aware of your surroundings and stay safe!
