It's a spray which helps to dissolve oil, fat , and wax stuff ... You can use it for all kind of stuff.
If you need to go for a service to clean a oil boiler that's the perfect product.
I remember back in the days using this stuff for cleaning nozzles, steal plate in front of the burner, inside the burner.

chlore free , dissolves all kind or particles,

I think it's worth using this stuff to get rid off sulfur.

and if your not careful it will probably clean away your brain cells, to be used in large airy environmeny very similar to ardrox which we used a lot in the RN

I've tried out duel x and soot breakers. Could be useful with really bad chamber. But settled on 10mins with good old brush, scraper and vac.

sorts out most boilers, but if they are particularly manky i break out this

Surely it will work with scraper ...
I used to use scraper too but sometimes the chambers are so big or awkward you can't rely on a brush or Hoover. Sometimes there is no space to get far enough with the Hoover therefore I'd use a chemical which will burn the rest of stuff away.
