Grout lines, oven racks and grill grates are the jobs where steam alone stops being enough and you need something abrading the surface while the steam softens it. The Reliable 100CHA30B is the 30 mm brass detail brush for the Pronto 100CH handheld steam cleaner, and it is the attachment to reach for when a nylon brush is just sliding over baked-on residue. Brass bristles are stiff enough to lift carbonized grease and ground-in grout soil, but softer than steel, so they scrub porcelain-coated grill grates and glazed ceramic tile without the chipping risk a stainless brush brings.
The brush threads onto the Pronto nozzle, which concentrates the machine 4-bar (60 PSI) steam output into a small working head. That combination is what does the work: the steam breaks the bond between the soil and the surface while the brass agitates it, so you clean without detergents on surfaces where chemical residue is a problem, such as food-prep areas, ovens and barbecue grills. Cleaning crews typically keep a brass brush and a nylon brush on hand and switch between them by surface hardness rather than trying to make one brush do everything.
This is a wear item. Brass bristles are intentionally softer than the surfaces they clean, which is the point, and it means the brush wears down faster than a nylon head under heavy use. Buying a spare is normal practice for anyone running the Pronto daily rather than occasionally.

Frequently asked questions
What is the difference between the brass and nylon Pronto brushes?
Brass is stiffer and is meant for hard, durable surfaces such as grout, grill grates and oven racks. Nylon is gentler and is the general-purpose choice for finer or softer surfaces. Most users keep both.
Will the brass brush scratch my tile?
Brass is softer than glazed ceramic and porcelain, so it agitates grout without scratching the tile face. Test an inconspicuous spot first on softer or unglazed natural stone.
Is this safe on porcelain-coated grill grates?
Brass is the safer metal choice for porcelain-coated grates. Stainless bristles are more likely to chip the coating.
Does this fit the Pronto 100CH?
Yes. The 100CHA30B is the factory 30 mm brass brush for the Reliable Pronto 100CH.
Do I need detergent with it?
No. The brush is designed to work with the steam output of the machine, which is why it suits ovens, grills and food-prep surfaces where chemical residue is unwanted.
