They are mostly cotton - a few poly/cotton mixes, and generally get washed at 40, the occasional 60.
This seems to be enough to get rid of any visible stain, and when I bring them in from the line they don't smell particularly. But I get a whiff of bo smell when I iron them although it seems to dissipate when they cool down and are hung up
What can I do about this - am a bit paranoid because I think when I'm wearing them my heat 'reactivates' the smell quicker than a brand new blouse - so I think they're not washing out properly.
I haven't done 90 degree washes because a few are coloured or stripy and worried about ruining them.
Any tips - thanks?
