Bicarbonate of soda takes away the mingy taste afterwards.
Good call, Alka Seltza is just glorified bicarb at 4 times the price.
Another tip, drop of vanilla essance in water left to soak for a bit will take away manky taste/smell from bottles but won't be enough to flavour drink after rinsing.
Well bicarb and citric acid to make the powder/fizz and aspirin to do the job.
I just rinse mine through and then every now and again use some milton, stronger than normal (of course you leave it for longer as well as you forget about it.
It's a Tesco cheap camel back but the bladder itself is better than a lot of the expensive ones I've seen. It' not 'plasticy'.
Never had a bad taste no matter what's been in it and never a bad build up. I just use the pre-made stuff (which is a bit different to the tablets). Tablets should be better. Tesco's also make their own version for cheaper if I remember correctly.
You tap water must be bad if you have to use bottled water, over here it's often the same stuff.
