I wonder how “mildly” acid it was?

I was in London a few weeks ago, I took a large 1 liter water bottle all over with me.

I think that in the future in addition to a bottle of water, a little bicarb or baking soda might be another good addition for this “new normal” of terrorism.

Another site reports (guesses?) that it was drain cleaner. Drain cleaners usually contain dilute sulfuric acid.

if this report is true, expect the UK to ban drain cleaners.

Mix the Bi-Carb or Baking Soda in the water and put a spray top on the bottle.
