Never knew that, always thought white grout was a sort of standard actually

Melamine is a kind of plastic right?

I don't think grout is blue, i never saw such colour grout before, hahaha

Used the HCL89 from http://hcl89.byethost10.com before and it really helped to clean my tiles, recommended

Pardon me but what does etched mean?

Tried the HCL89 thing before from http://hcl89.byethost10.com the marble tiles at my side became spotless. Would recommend for those that want to diy

I tried thiiner before, white blotches everwhere

I also use the product from http://hcl89.byethost10.com experience was same as yours, manage to settle my dirty grout/glass mildew problems

You can use something called HCL89. Its strong enough to clean the mould as well as kill it I usually get it from http://hcl89.byethost10.com or http://hcl89.atwebpages.com One thing i like about it is that is creates like a protection like on my wall/tiles so that it prevents future mould or etc Hope this helps you out

So far not bad, i used it on homogeous tiles and my glass shower screen as well

You need to maintain your wall tiles so that it will always remains dirt free. In my case i use something called HCL89. I usually get it from http://hcl89.byethost10.com or http://hcl89.atwebpages.com What it does is that it cleans your wall tiles and also helps to create a protection for it so that always remains new.

I reckon should be either to non usage or over usage

I guess when a product is good, users will tend to recommend it to each other, ie (word of mouth) Anyways i rememeber you are the one with the water stains in the below thread http://www.renotalk.com/forum/index.php?showtopic=58037&st=0&gopid=784326entry784326 By the way i used the HCL89 thing as i was having the same problem as you but have i updated my post in the above thread

I tried JIF before, simply does not work at all, infact problem became worse. I also have the same problem as taitaineo and have run out of solutions, anyone has any suggestions?
