remove alumina from the stainless steel base

I have a ss bases filter. There is contamination of trace alumina formed on the surface (cannot see by eyes. It is found by SEM). Any idea on how to remove it using chemicals but without attacking the stainless steel metal base?

Thanks.

Can I ask what condition? such as concentration, temperature, leaching period?

Thanks.
