Hi newbie's first proper post here.
I get my citric acid from places that sell soap making ingredients - there are lots online if you do a search.
I use it to make bath fizzers
The trouble is shipping can be expensive - especially if you just want a bit.
Ebay is quite useful for small quantities.
I've also been lucky enough to find it in Asian foodstores.
Mind you I now use so much I get it in 5 kg buckets from soapmaking suppliers
I also buy bicarb (another key ingredient) in 12 kg sacks from my local food weigh house.
I used to get funny looks till I took some bath fizzers in for the ladies behind the counter
Hope this is useful
Thanks
Pogo
