Bleach
Hi
On a roll today.
Bleach, we all use it, but it costs a mint.
All down to packaging and transportation costs.
Buy the tablets, same stuff, just as effective.

1 tablet is the same as 1 litre of bleach.
If you are a real freak, use two.
Even at that strength you get 1800 litres of bleach.
A fantastic saving.
