Spear jackson heavy duty sink and drain unblocker gel -is this sulphuric acid

Not that I remember re sulphuric acid but the product was not as good as I was hoping.

I think i may have candle wax far down my drain, will this remove it please?

Probably. Boiling hot water should work, also. I'd try that first as it's free.
