OATEY 35100 Hercules® 113 Gram Scout Boiler Cleaner

Scout is a liquid boiler cleaner that pulls rust, scale, oil, foam and other impurities out of pressure vessels, steam kettles, heat exchangers, steam generators and tanks. The active ingredient is trisodium phosphate (TSP). It goes to work on the deposits that cause carryover and foaming in a steam system rather than on the water hardness itself.

No draining or flushing is required. Scout removes rust, scale, oil, foam and impurities while the system stays filled, which is what makes it usable on a live plant where you cannot take the vessel down for a full flush and refill.

Yes, that is the case Scout is built for. Oil and surface impurities are the usual cause of foaming and carryover in a steam boiler, and the TSP in Scout removes oil and foam along with rust and scale, without taking the system down to drain it. Applies to steam generators and pressure vessels as well as conventional boilers.

Scout is described as non-toxic and odorless, and steam kettles are named among the equipment it cleans. That covers the kitchen and cafeteria steam equipment a facility maintenance crew deals with alongside the boiler itself.

Order Oatey part 35100. That single MPN covers the 113 gram Hercules Scout boiler cleaner, so there is no size, finish or pack option to specify on the order.

No. Scout is a cleaner, not a feedwater treatment or softener. Its job is removing deposits already in the vessel, rust, scale, oil, foam and impurities, from pressure vessels, heat exchangers, steam generators and tanks. If the incoming water is the reason scale keeps coming back, you need a separate water treatment or softening program alongside it.

The 35100 is the 113 gram size of Hercules Scout, a single-model item with no other fill sizes offered. Shipping weight is listed at 0.3 and volume at 0.013, so this is a small dosing container meant for treating a vessel, not a bulk drum for a boiler room program.
