Custom Cleaning Brush
Sponge Chimney
Sponge Chimney is built for duct, vent, and chimney where the brush must enter or follow duct walls, dryer vents, and flues. Head size, working length, stem flexibility, and fill are selected to loosen lint, soot, and dust without losing access or control.
Product Features
Soft sponge element wipes inside ducts or flues — The head removes loose soot and fine residue with broad contact.
Compressible shape follows passage variation — The sponge adapts to minor diameter changes.
High debris and liquid carrying capacity — Porous material can collect dust or distribute cleaning solution.
Pull-through and rod-mounted options — The head can be used with ropes, rods, or flexible shafts.
Replaceable sponge section — Worn or contaminated heads can be changed.
Sponge head matched to the flue — Diameter, length, sponge density, core, connector, and cleaning method can be customized.
Product Overview
Sponge Chimney uses a working section shaped around the available opening, depth, and internal profile. It contacts duct walls, dryer vents, and flues to remove lint, soot, and dust; the access path and minimum clearance determine whether the brush needs a rigid stem, a flexible extension, a tapered head, or a stepped cleaning section. The flexible rod, brush diameter, joint, working length, and bend radius must reach the complete passage without separating.
Key dimensions start with Brush head diameter 100–600 mm, Brush head length 80–300 mm, and Handle length 1–10 m mm. The product follows an internal-cleaning brush structure for pipes, holes, and narrow channels. The specified interface is threaded removable / fixed. PVA Sponge and PU Sponge are the principal material directions in the current specification. The stroke, guide clearance, and flexible length must be checked against the complete movement envelope.

Application Areas
Sponge Chimney is primarily mapped to Tube & Pipe Cleaning. For a new use case, check the surface material, debris flow, and finish requirement before fixing the brush design.
- Sponge Chimney is best suited to chimney, flue, smoke-pipe, and fireplace passage cleaning.
- The twisted-in-wire, flexible-rod, pull-through, fan-tip, or powered bore brush follows masonry, stainless, clay, or metal flue wall and cap passage while the fill displaces soot, ash, creosote, scale, and loose combustion residue.
- Use this configuration when the available access supports radial filament contact inside a bore, tube, hose, channel, nozzle, or drilled passage.
Selection Guidance
Structure fit
Match the tube & pipe bore brush geometry to duct walls, dryer vents, and flues, the available access, and reciprocating motion. Confirm Brush head diameter 100–600 mm, Brush head length 80–300 mm, and Handle length 1–10 m mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PVA Sponge and PU Sponge according to the behavior of lint, soot, and dust, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Brush stiffness depends on the material plus filament diameter, free trim length, and fill density.
When to use another solution
For Sponge Chimney, use another cleaning method when lint, soot, and dust cannot be released by controlled filament contact, when duct walls, dryer vents, and flues cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should Sponge Chimney be selected?
Start with chimney, flue, smoke-pipe, and fireplace passage cleaning, masonry, stainless, clay, or metal flue wall and cap passage, and soot, ash, creosote, scale, and loose combustion residue. Then set Flue diameter, Brush head length, and Rod reach, choose the fill from the material and residue table, and match the mounting interface and operating condition.
Which dimensions define Sponge Chimney?
The primary dimensions are Flue diameter (100–600 mm), Brush head length (80–300 mm), and Rod reach (1–10 m). Also provide the minimum clearance, working envelope, trim or engagement, and the existing holder, shaft, stem, thread, or handle.
Which filament or contact material is used for Sponge Chimney?
The primary options are PVA Sponge and PU Sponge. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Sponge Chimney not the best cleaning method?
Sponge Chimney is not the first choice for pigs, flushing, ultrasonic, chemical descaling, blasting, or a flexible cable system for long, sharply curved, or heavily scaled passages.
What information is required to quote Sponge Chimney?
Send the part or machine drawing, photos of masonry, stainless, clay, or metal flue wall and cap passage, Flue diameter, Brush head length, Rod reach, and Connection, the residue description, wet or dry conditions, motion or use method, temperature, preferred PVA Sponge and PU Sponge, quantity, and the existing interface or sample.
