Hi guys i was wondering if any of you can help me on this
my car porch granites tiles are turning yellow....

Some of the yellow thingy are dirt and dust... I have tried using scrubbing using soap..
but can only clean like 70% of it but the yellow dirt still remains



I tried using acid (the yellow colour one) and it can remove the yellow dirt but the nice granite surface is like gone already



the 2 tiles on the left are the original color.... the big tiles on the right is the one i use acid to wash..

can anyone suggest what is needed to use to clean this once and for all...

just change tiles or use imprint concrete

do you know roughly how much it will cost?

imprint concrete still need to take care & maintain, tiles 0 maintenance


granite stone is one class above tiles wor, so not need to change lar. call the professional marble/ granite guy to buff/ scrap it off with machine then apply a protective coating will do

nice


I go check and see can or not ... bust surely going to be damaging....

I face the same problem also. But please dont use acid, my car porch granites tiles use acid to try for few pieces, end up cant remove the problem like you mentioned, somemore, the surface now becomes very dull, before that, quite shiny. Regreted and the cleaners cant do anything on it.

Have you seen this?

Wah granite! Can try WD40? Used it to clean some stubborn stains on my tiles and it worked. Not sure if it works for granite though.

i've try use chemical to remove yellow stain on marble,it may work on granite too, but can't remember the exact name is.
will try to check and post here


granite tiles /= granite lar

not that expensive, is only <rm200 for 18L packing

is it ??

do you know the brand name ... or the shop that sells?

BTW....can you tell what brand of granite tiles that you were using here??? so that we can know whether it is tile production issue(so we can avoid) or its just any granite can turn ugly like that....

Hi there,

Sorry to interrupt, Granite Tiles actually is not produced in factory like Tiles.. What I mean here granite are natural stone.. Actually this problem are common in Natural Stone product such as Granite, Marble and Limestone.. All these are rainwater mark stain... Maybe you can try called up some Granite Supplier for removing the stain and follow by Protective coating..
