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...
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. my car porch granites tiles are turning yellow....
