White bedding and how to keep it white
Short answer: White bedding turns grey from dye in other laundry and yellowish from cream and sweat. Wash it on its own at 40 degrees and avoid chlorine bleach.
Wash white on its own
A grey cast comes from dye in the machine, not from dirt. Gather the whites and wash them together.
Yellowish marks
Cream, hair products and sweat cause yellowish marks, especially at the pillow. Soak them before washing if they have set.
No chlorine
Chlorine bleach breaks down bamboo viscose and eventually gives a yellowish cast. Use an ordinary detergent.
Sun on the line
Sun has a mild bleaching effect, which is an advantage on white. See how white clothes stay white.
Change the pillowcase more often
The pillow gets dirty fastest. See bamboo bedding.
No fabric softener
Fabric softener binds residue and makes white go dull over time. See how to wash bamboo bedding.
