Storage sodium chlorite & Hcl

Hi, I purchased sodium chlorite and hydrochloric acid 1 year ago, and have kept the solutions in the original plastic bottle containers. Does anyone know if it is safe to use? I heard some people store these solutions long-term in opaque glass bottles.

ok thanks I'll take a look at your website.
it's sodium chlorite 22.4%, and Hcl 4%.
they came in non-transparent white plastic containers and have been kept in the dark cupboard for a year.
I'll get the test strips too.
any other suggestions?
Thanks again!
