Distiller water is hard and expensive to get hold of in the UK. It used to be that chemists sold large amounts of it but not anymore, and as expected delivery prices are insane.

Last time I boiled lobsters I used de-ionised water, or battery top-up water, thinking it was the same thing. now i know that de-ionised water is water that is purified using chemical filters including lye. Is this stuff alright to use? I know it uses chemical filtering but the final product is close enough to pure water, right? It worked fine last time, but then I guess I probably wouldn't have noticed the difference even if I had just used tap water (not that I would do this).

I'm also planning on giving my product (the cooked lobsters) a sodium carbonate wash if that would make a difference.

Thanks for the help

Tap water is fine and a sodium carb wash will make those lobsters taste delicious!

I doubt de-ionized water would make a difference, i may be wrong though.

So I could just use tap water instead of distilled or de-ionised..?

This would clearly be much more cost beneficial. Tap water in the UK is notoriously clean, but would it really be okay for a chemical (seafood) procedure?

I use de-ionised water when I am being careful, but have used tap water with no issues too.

Ive used both with no noticable difference.

yep me too

This worm has dreamed of D-water, Brita filtered water and tap water. All have worked the same.
