Tile & Grout question

[floorguy]

So I just cleaned this house today. everything tile, or laminate.

anyway, down stairs they had this area where the hot water heater leaked, and pooled in this area....

no one really knows how long it sat...

but it has whitened the grout, and had left the tile lighter to...though that cleaned up....







i tried a mild acid on it and nothing....

so what do you all think????

i tried a mild acid on it ....

What do mean by "mild"?

A high pH? Dilute? or ???

 

[Johnny]

Rust?

Try a stronger acid. If no workee, then forgetee.

Hard water deposits from bottom of tank ? What was used to clean it up , chlorine..?

a brown away product....

not rust, because the normal color is red...its the white that i am wondering about...

Calcium looks like that, and is something a water heater could/would have in it.

Wouldn't the water have to evaporate to leave that much behind? Maybe they did bleach it...

Treat it like "efflorescence" Use stone pro quick clean, or viper renew. Scrub in, dwell, rinse with a turbo.

Use a color enhancer on the grout lines. It will make them look brand new

 

[Steve Lawrence]

Is it possible that the grout had been color sealed and the standing hot water removed it?

 

[floorguy]

i think its colored grout
