Does anybody have any tips on cleaning exhuast stacks?
20%Ph acid mixed brightner for the hard black soot on the exaust tips and elbows down by the cab ,applied with #4 steel wool or scratch less dish hand pad. Once you get them clean the first time and they get washed at least twice a month,then I normally just sprinkle non scratch ajax,comet on my stack brush. Spray n wash works well to.
Be carful with PH acid around polished aluminum. If the unit is ,I’d go with a mild citric acid a the above products
Great! Thank you
