Food stains on storage containers

Dunno but they come up lovely if you have a dishwasher.
We used to have one and my processor blade always goes pink after processing anything with tomato puree in.Just have to avoid it now.

Cheaper than baby sterilising tabs ....

best advice my Mother *ever* gave me!

mmm seeing as sterilising tablets are basically bleach I expect diluted thin bleach (not Domestos-style thick bleach) would do the same thing. Logical really.

No really, they are.

The active ingredient in sterilising tablets is di-Chloroisocyanurate acid (Sodium Dichloroisocyanurate, NaDCC). _{(Yes I did have to copy and paste that name )}. When dissolved in water this creates a chlorine solution and when used to clean baby bottles is at very low concentrations (about 250 parts per million (ppm) chlorine).

Thin Bleach is just a solution of Sodium Hypochlorite in water (usually about 4% free chlorine, 40000ppm, at time of manufacture). So if you put 5ml (1 teaspoonful) of thin bleach in 1 litre of water, you will get a solution of approximately 200ppm.

Solutions of bleach of this sort of concentration are often used to sanitise dishes, utensils and work surfaces in commercial kitchens (after normal cleaning and rinsing).

I'm not recommending you use bleach to sterilise baby bottles (for a start it's a lot easier to get the dose right using solid tablets), but just saying that as the active ingredient is the same in both these tablets and thin bleach you could use very dilute bleach to remove stains from plasticware - just make sure they are well rinsed afterwards.


I found this page about commercial sterilising tablets (the same substance as the ones you buy for baby bottles just bigger tablets) which details some pretty amazing uses for chlorine.
