Hi Lawyer... Sorie a bit busy lately , so no time to test out & reply u ... BTW , just bought a BLEACHING WATER ( ACID ) from Hardware Store , cost me RM3 for a small bottle ..... i have Tried using it on the tile... It works... It actually removes the layer/ sheen of of dirt /dust / plaster / cement .... Havent removes 100%  but almost 80% of it ... maybe bcos i Tried on time only , maybe need to do a few rounds... 

But , guys ... If u r using it , BE VERY VERY CAREFULL & PLEASE USE GLOVE... THE BLEACHING WATER ( ACID ) IS VERY ACIDIC... Can see smoke coming out after u pour it out.... , Come to think of it mayb i should use a Tile Cleaner instead...

Note: The bleaching water is used to clean cement/super-dirt/etc from your tiles.  It reacts to form ammonia (that's why very very smelly).  Very much recommended when you first plan to move in.  Don't use it around the edges or it'll eat into the tile filling at the side.  It's not used to polish tiles.

Lawyer1,
Got the shop name?  I'm staying in Seri Kembangan, may try it out one of these days .  Most shops closed for CNY today...

Hi CW,

Well, I'm sorry, I haven't called them before. If possible, can you please call them and ask ? The number is 89488343. Thanks, CW,.....

Nobody picked up.  I guess they're still on holiday.

Thank you. Is this Bleaching Water you talked about in yellow or clear colour please ?

I have used both of the yellow and clear -colored acids on my tiles, but they still look hazy at many places. Again, perhaps the Tile Cleaner is the 'specialized' cleaner for this problem ?

We should try it out,.......

Hi... I used the Clear One " Bleaching Water " , after a few rounds it works for mine... It has cleared / cleaned off the layer of Hazy sheen.... , & let us know the Result for using the Tile Cleaner too.. It maybe a good option since " Bleaching Water " is a bit harsh...
