Texwipe STX1722 Sterile Revolve BetaMop Tubular Polyester String Replacement Heads (Refills)

Purpose & Scope

The STX1722 are sterile tubular string replacement mop heads for the BetaMop® platform, manufactured using Revolve® upcycled polyester. String mops are typically selected for larger floor areas and higher liquid loading, where coverage efficiency matters. In sterile environments, this increased capacity must be balanced with solution control, zone discipline, and objective change-out rules so sustainability does not introduce variability or re-deposition risk.

Visual Aids (Technique, Zoning, Lifecycle)

Use this graphic to reinforce zone sequencing, lane discipline, and mop head lifecycle control. String mops magnify both good and bad technique.

Implementation note: Higher liquid capacity increases coverage—but also increases re-deposition risk if change-outs are delayed.

Sterile Handling (Large Mop Heads, Larger Risk Envelope)

Tubular string mop heads present more surface area and more handling opportunity than flat covers. The most common sterile deviation is touch transfer during setup—sterile heads handled with gloves that contacted bucket rims, wringers, cart rails, or door hardware.

• Open at point-of-use: avoid staging opened sterile mop heads.
• No contact staging: do not rest sterile strings on floors, bucket rims, or carts.
• Glove transfer rules: define corrective action if gloves touch non-sterile surfaces during setup.
• Controlled removal: remove and discard used heads without contacting clean tools or packaging.

String Mop Behavior in Aseptic Cleaning (What Changes vs. Flat Mops)

Tubular string mops hold more solution and can cover larger areas quickly. That same capacity can accelerate solution loading and re-deposition if lane discipline and solution change-out rules are not enforced.

• Higher liquid retention: improves coverage efficiency but increases drip/splash risk.
• Less defined edge control: requires deliberate perimeter management.
• Change-out sensitivity: string mops can look usable while already overloaded.

Wetting & Wringing Control (Critical for String Mops)

With tubular string heads, wringing discipline is one of the most important controls. Over-wet string mops drip, splash, and spread contamination instead of capturing it.

• Uniform wetting: ensure even saturation before wringing.
• Consistent wringing: use a defined wringing method (cycles/pressure) per SOP.
• Drip check: if it drips during transport, wring again before entering the work zone.
• Re-wring vs. change: if streaking persists after wringing, change the mop head.

Technique: Large-Area Unidirectional Floor Cleaning

• Clean-to-less-clean sequencing: align lane direction with your zoning map.
• Defined lanes: avoid random sweeping motions that redistribute solution.
• No backtracking: do not pull loaded strings back over cleaned floors.
• Perimeter control: manage edges separately to avoid pulling debris inward.

Objective Change-Out Triggers (Sterile Revolve® String Mop Heads)

Sustainability goals should never extend use windows in sterile programs. String mop heads require strict, objective change-out criteria.

• Change by zone boundary: never carry used heads into cleaner zones.
• Change by stage: perimeter/entry work should not share heads with critical interiors.
• Change by performance: streaking, haze, visible soil load, increased drip after wringing.
• Change by handling event: dropped head, torn packaging, uncontrolled staging, touch contamination.

Details Most Websites Skip (String Mop Reality)

• “Looks clean” trap: string mops can appear usable while already overloaded.
• Drip trail risk: over-wet strings create contamination trails between lanes.
• Wringer contamination loop: pressing heavily loaded strings into the same wringer concentrates soils.
• Sustainability drift: extending use for environmental reasons undermines audit defensibility.

SOP & Audit Readiness Checklist (Sterile Revolve® String Mop Heads)

• Define sterile opening, seating, and removal steps for large mop heads.
• Define wetting and wringing targets (uniform saturation; drip control).
• Define lane technique and perimeter management for large floor areas.
• Define objective change-out triggers (zone, stage, performance, handling events).
• Document that sustainability goals do not alter sterile process controls.
