I need to refresh some old yellowed wall tile grout - are those paint
pens any good or am I stuck with raking it out and re-filling?
Thanks

Hi Peter
I cleaned mine by spraying it with a bleach solution ,
approx 30% bleach, leaving it for 24 hrs and then rinsing off , It
removed what mould was there and all came up really white. Might be
worth a try before raking it all out.

Thick bleach is good for this too, paint on, leave for 30mins, scrub
with nail brush and repeat throughout the day as a background task.
