## Questions & Answers

**Q: Do they contain bleach?**
A: They work by giving a very faint blue tinge to your wash, which removes the yellowish tint that a white wash can sometimes get.

Having said this, I don't know if they do contain bleach, but they don't have a bleaching effect, anyway.

As they do tint washing blue, they should be used only in very small quantities, I find less than a quarter of one block is enough for an average wash.
