Custom Cleaning Brush
Sponge Cup
Sponge Cup gives the operator controlled access to sponge cup contact surfaces, adjacent edges, and mounting features for sponge cup cleaning and maintenance. Head shape, reach, handle form, and filament stiffness are matched to beverage film, milk residue, and oil and the available working space.
Product Features
Soft cup-shaped sponge contact — The head wipes curved surfaces and holds cleaning liquid.
Compressible working face — The sponge conforms to bowls, cups, and recessed cavities.
High liquid retention — Porous material carries detergent or rinse water.
Low-scratch cleaning — Suitable for glass, plastic, coated, and polished surfaces.
Replaceable head options — Worn sponge cups can be changed independently.
Built to the tool — Diameter, depth, sponge density, core, handle, and connection can be customized.
Product Overview
Sponge Cup starts with how the operator reaches and sees the cleaning zone. The brush should place the active tips on sponge cup contact surfaces, adjacent edges, and mounting features, dislodge beverage film, milk residue, and oil, and keep the handle, ferrule, or rigid backing clear of nearby parts. The sponge cup working face must reach the complete residue path while the holder remains clear of the part.
Key dimensions start with Brush head diameter 20–70 mm, Brush head length 120–300 mm, and Handle length 200–450 mm. The brush uses a manually controlled detail-brush structure for precise access. The specified interface is fixed. PVA Sponge, PU Sponge, and Silicone are the principal material directions in the current specification. Handle length, neck shape, and head size should support comfortable control and avoid excessive contact pressure.

Application Areas
Sponge Cup is primarily mapped to Cup & Mug Cleaning. For a different application, first confirm the surface, where the loosened debris will go, and the finish you need.
- Sponge Cup is best suited to cup, mug, bowl, jar, and smooth-container wiping.
- The hand-held block, handled detail, cup, swab, applicator, or specialty brush follows glass, ceramic, stainless steel, coated cups, bowl interiors, and curved container walls while the fill displaces beverage film, milk residue, oil, foam, and light food soil.
- Use this configuration when the available access supports localized manual contact on accessible faces, corners, grooves, fixtures, and equipment details.
Selection Guidance
Structure fit
Match the handheld detail brush geometry to sponge cup contact surfaces, adjacent edges, and mounting features, the available access, and manual operation. Confirm Brush head diameter 20–70 mm, Brush head length 120–300 mm, and Handle length 200–450 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PVA Sponge, PU Sponge, and Silicone according to the behavior of beverage film, milk residue, and oil, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Choose stiffness by looking at filament size, free trim length, and density together with the material.
When to use another solution
For Sponge Cup, use another cleaning method when beverage film, milk residue, and oil cannot be released by controlled filament contact, when sponge cup contact surfaces, adjacent edges, and mounting features cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should Sponge Cup be selected?
Start with cup, mug, bowl, jar, and smooth-container wiping, glass, ceramic, stainless steel, coated cups, bowl interiors, and curved container walls, and beverage film, milk residue, oil, foam, and light food soil. Then set Head diameter, Working length, and Overall length, choose the fill from the material and residue table, and match the mounting interface and operating condition.
Which dimensions define Sponge Cup?
The primary dimensions are Head diameter (20–70 mm), Working length (120–300 mm), and Overall length (200–450 mm). 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 Cup?
The primary options are PVA Sponge, PU Sponge, and Silicone. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Sponge Cup not the best cleaning method?
Sponge Cup is not the first choice for a tube brush, powered brush, scraper, wipe, sponge, or vacuum when the target is internal, heavily bonded, or highly delicate.
What information is required to quote Sponge Cup?
Send the part or machine drawing, photos of glass, ceramic, stainless steel, coated cups, bowl interiors, and curved container walls, Head diameter, Working length, Overall length, and Filament diameter, the residue description, wet or dry conditions, motion or use method, temperature, preferred PVA Sponge, PU Sponge, and Silicone, quantity, and the existing interface or sample.
