Just wondering if anyone of you guys know how to clean the in between tiles lining to white from black.
I tried the (forgotten what brand) bleach and put there for 5 - 10min, brush with toothbrush, no use.
My mom told me before there's one out door sales girl came to our house, trial on our tiles and it works flawlessly! Till now, it is still quite white tho.
I feel like purchasing it but I lost the name card. I'm just wondering if anyone of you guys have other method on cleaning the tiles lining tho.
