chlorinated, but the rest of the formulation is a ???? I used Gunk brand recently, it did a decent job, albeit a tad slowly. There were some "crusties" that refused to give
& required some extra attn., but considering the carb. sat unused & a combo of corrosion & varnish/deposits festered for 18 years, it did OK.
