Default How to make white grout white again?


I have this problem especially in the bathroom. The grout turns yellow and even if I clean it with bathroom soap and muriatic acid, it doesn't help.

Thanks

What about Mr. Muscle cleaner, has anyone tried this? Is it really effective?

This may sound crazy but have you tried using rust converter? The phosphoric acid might do the grout some good. Just be sure to dilute it.

In some cases it would be easier to re-grout than to clean stained grout.

Thanks. but the problem is, after a few months, it gets somewhat yellowish again.

Someone told me to use hydrogen peroxide and a toothbrush. Saturate the brush in a glass of the peroxide, then dip and scrub to clean the grout lines.

I haven't tried this yet but they say it really works.

I'll post my feedback after trying it.

I tried using hydrogen peroxide to clean the grout this weekend.

Well, some things just don't work as you expect it to be.

somebody also told me about the sealant. this looks like clear coat paint that you apply on cars. but i have to remove the existing grout and put a new one before applying the sealant.

i was just hoping that i could make the existing grout white again without removing and applying another one. but if there's no other way then that's what i'm going to do.

that's how i'm doing it as well (re-grout... madali lang naman...ata.) once i'm able to purchase the sealant and scheduled a weekend... baka gawin ko rin sa bathroom floor tiles' grout namin

para sa akin mas madaling mag-regrout pero matrabaho ang mag alis ng grout.
