how to keep whites white

[mimmytoz]

thats it really.
its white school shirts if that makes a difference

dh has white shirts and to keep them white I always wash them with other whites, I use bio powder and a scoop of Vanish oxi action crystal white.

Bio powder not liquid and only wash with other whites. Dry outside if you can.

Twice the usual amount of bio powder (aldis tested better than Persil when which? Tested them).

60c wash.

Do NOT press the quickwash/rapid wash button.

Put the powder in the drum, not the drawer.

Et voila. White whites.

I dont wash above 40 apart from towels/bedding
