For this Tee in Particular, we used Oxygen bleach and an all natural stain remover bar.

Oxygen Bleach is not as harsh as other Chemical bleaches.
Rather than being like bleach and removing colour from garments and damaging the cotton fibre, Oxygen bleach works on the nasty stains and simply breaks the stain down and pulls it out of the clothes without damaging the garment.

Soaking timeframes will depend on product instructions. Usually around 30 minutes for minor stains or coloured tees ensures the tee is not being over exposed to the Oxygen bleach.
