Hey everyone,

Been asked to clean some (exterior) white porcelain tiles (with white grout).  Not familiar with best way forward on this one, as I’ve not done porcelain before.  Any advice gratefully received.  I’ve got a decent fsc if that’s any use.

Black grout!

you can p/w cold and use hypo - if in doubt test one in the corner

or use hot steam

You could just apply a hypo mix scrub with a brush and rinse with the garden hose job done
