"Uchafu utaondolewa"

Translation: Dirtiness will be removed

[ma_drane]

What is the difference between kuondoa and kutoa ?

[shakir.mol]

Ondoa is more like remove and toa is to take out
It's similar but ondoa can be non physical but toa is like toa kitabu chako from your bag for example

[Anjee99]

Can it be "The dirt will be removed"?

[Norman501963]

"The dirt will be removed" is correct.
