Clean glazed surfaces and facades
This element covers the essential knowledge and practical skills for cleaning glazed surfaces and façades, such as windows, glass doors, and curtain walling, in commercial and public settings. Learners will understand the theory behind safe access, appropriate tool and detergent selection, and systematic cleaning techniques, and will demonstrate competence in achieving a streak-free finish and restoring the work area to a tidy, safe condition. Mastery of these skills is critical for maintaining professional building appearances, ensuring occupant satisfaction, and prolonging the lifespan of glazing materials.

Topic Overview
The IQ Level 2 Certificate in Cleaning and Support Services Skills provides foundational knowledge for anyone pursuing a career in professional cleaning. It covers key areas such as health and safety legislation (including COSHH and RIDDOR), cleaning methods for different surfaces, waste management, and customer service. Students learn to work safely and efficiently in various settings like hospitals, offices, and schools.
This qualification is part of the Service Industries suite and is recognized by employers across the UK. It emphasizes practical skills like using cleaning equipment, selecting appropriate chemicals, and following infection control procedures. Understanding these topics is crucial for maintaining hygiene standards and preventing cross-contamination.
The course also develops soft skills such as communication, teamwork, and time management, which are essential for working in support services. By mastering these competencies, students can progress to supervisory roles or specialize in areas like healthcare cleaning or environmental services.
Key Concepts
Core ideas you must understand for this topic
- →COSHH regulations: assessing risks, using safety data sheets, and storing chemicals correctly.
- →Colour coding system: using different coloured equipment (cloths, mops) for different areas to prevent cross-contamination (e.g., red for toilets, blue for general areas).
- →Infection control: understanding pathogens, transmission routes, and disinfection methods.
- →Waste segregation: separating general, clinical, and hazardous waste as per legal requirements.
- →Customer service: communicating politely, respecting privacy, and handling complaints.
Learning Objectives
What you need to know and understand
- understand how to clean glazed surfaces and façades, understand how to finish cleaning glazed surfaces and façades, and reinstate the work area, be able to clean glazed surfaces and façades, be able to finish cleaning of glazed surfaces and façades, and reinstate the work area
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct risk assessment and selecting safe access equipment (e.g., ladders, mobile platforms) in compliance with working at height regulations.
- Award credit for achieving a uniform, smear-free finish free from drips, runs, and residue on all cleaned glazed surfaces.
- Award credit for safely storing cleaning equipment and correctly disposing of waste materials, leaving the work area clean, dry, and hazard-free.
- Award credit for identifying and reporting any pre-existing damage or defects on glazed surfaces before commencing cleaning.
Assessment Guidance
Guidance for achieving higher grades
- 💡In practical assessments, always start with a visual survey and verbally confirm that the area is safe to clean, mentioning any specific hazards.
- 💡Follow manufacturer’s dilution ratios precisely for cleaning chemicals, and demonstrate the use of a colour-coded system (e.g., red cloths for high-risk areas) if applicable.
- 💡Check finished surfaces from at least two different angles and under varied lighting to verify a streak-free result before declaring the task complete.
- 💡When reinstating the work area, show awareness of environmental considerations, such as recycling containers and avoiding chemical runoff into drains.
- 💡Always use correct terminology like 'disinfectant', 'sanitise', 'decontaminate' – they have specific meanings.
- 💡In questions about procedures, list steps in chronological order and include safety checks.
- 💡For calculations, show your working and include units in the final answer.
Common Mistakes
Common errors to avoid in your coursework
- Neglecting to inspect glazed surfaces for cracks, chips, or seal failures before cleaning, which can lead to water ingress or further damage.
- Using abrasive cleaners or wire wool on tinted or coated glass, resulting in irreversible scratches and surface degradation.
- Failing to erect warning signs or barriers around the work area, creating slip hazards from splashed water or cleaning solutions.
- Applying cleaning solution directly to glass in direct sunlight, causing rapid drying and streaking before proper removal.
- Mistake: Thinking all cleaning chemicals can be mixed to increase effectiveness. Correction: Mixing chemicals (e.g., bleach and ammonia) can produce toxic gases; always use as directed.
- Mistake: Believing that a visible clean surface is also hygienically clean. Correction: Disinfectants need contact time to kill germs; wiping immediately may not be effective.
- Mistake: Assuming PPE is optional for quick tasks. Correction: Even short exposure to chemicals can cause harm; PPE must be worn whenever handling hazardous substances.

Detailed solution breakdown for typical exam problems
Question: A cleaning operative is tasked with cleaning a spill of unknown liquid in a hospital corridor. Describe the steps they should take to ensure safety and effectiveness. (6 marks)
- 1.Step 1: Cordon off the area to prevent access and display warning signs.
- 2.Step 2: Assess the spill – identify if it is hazardous (e.g., blood, chemical) using spill kit or safety data sheet if available.
- 3.Step 3: Put on appropriate PPE: gloves, apron, and goggles.
- 4.Step 4: Use absorbent material from a spill kit to contain and soak up the liquid.
- 5.Step 5: Dispose of waste in a biohazard or chemical waste bag as per COSHH.

Question: Calculate the dilution ratio for a cleaning solution if 50ml of concentrate is mixed with 2 litres of water. Express as a ratio (concentrate:water).
- 1.Step 1: Convert both quantities to the same unit. 2 litres = 2000 ml.
- 2.Step 2: Ratio = concentrate : water = 50 ml : 2000 ml.
- 3.Step 3: Simplify by dividing both sides by 50: 1 : 40.
