What is the Best Thing to Clean uPVC?
uPVC, which stands for unplasticized polyvinyl chloride, is a popular material used for window frames, doors, soffits, fascia boards, and other exterior fittings in homes and buildings. It’s durable, low-maintenance, and resistant to weathering, making it a go-to material for many construction projects. However, over time, uPVC can accumulate dirt, grime, algae, and other marks. This is where uPVC cleaning becomes essential.
What is uPVC?
uPVC is a hard, rigid plastic used primarily in the construction industry. It’s most commonly seen in window frames, doors, and exterior cladding. Additionally, soffits and fascia boards, which form part of a building’s roofline, are often made from uPVC. These components are exposed to the elements and are particularly susceptible to dirt, algae, and general wear and tear.
uPVC is valued for its longevity, resistance to corrosion, and ease of maintenance. However, regular cleaning is required to keep it looking new and to prevent staining or degradation. Cleaning uPVC is now an industry in itself, with many companies offering specialized services to keep it pristine.
The uPVC Cleaning Industry
Cleaning uPVC has evolved into a niche market. Over the years, companies have developed methods and products specifically designed to clean uPVC without causing damage. This has led to a thriving uPVC cleaning industry that focuses on removing stubborn marks, dirt, algae, and even discolouration. Professionals in the field use a variety of equipment and chemicals to achieve the best results, often offering services to clean soffits, fascias, window frames, and even uPVC cladding on buildings.
Because uPVC is a relatively tough material, cleaning it involves using the right chemicals and tools to avoid scratching or damaging the surface. For homeowners and cleaning professionals alike, it’s important to know what to use to keep uPVC looking as good as new.
Caustic vs. Non-Caustic Chemicals
When it comes to cleaning uPVC, there are two broad categories of chemicals: caustic and non-caustic. Understanding the differences between these types is key to choosing the right products for your cleaning needs.
Caustic chemicals are strong and aggressive cleaners, often used to tackle tough stains and grime. These chemicals, such as sodium hydroxide or bleach-based cleaners, can dissolve grease, dirt, and organic material. However, they can also be harsh on surfaces, and using them incorrectly can result in discolouration or damage to the uPVC material. As a result, many cleaning professionals avoid using overly caustic substances on uPVC.
Non-caustic chemicals, on the other hand, are much gentler and safer for use on uPVC surfaces. These cleaners rely on enzymes, mild detergents, or surfactants to lift dirt and grime without damaging the surface. They are effective for everyday cleaning and maintenance, and they can even be used on delicate surfaces like uPVC fascia and soffits.
Common Chemicals Used for Exterior Cleaning
Several chemicals are commonly used by exterior cleaners to maintain and clean uPVC. Some of the most widely used products include Ubic and Virosol, which are both formulated for cleaning various surfaces, including uPVC.
Clover Ubic 200 is a powerful cleaner sold by places such as window cleaning stuff. It known for its ability to remove dirt, algae, and other stains from uPVC. It’s often used by professional cleaning services for large-scale cleaning tasks, such as cleaning entire buildings or areas with heavy grime build up. Ubic is effective at breaking down organic material, such as algae, but it is also gentle enough not to damage the surface of uPVC.
Viro-sol, another popular cleaner, is typically used for removing algae and moss from outdoor surfaces, including uPVC. It works by attacking the organic matter, breaking it down, and lifting it off the surface. This cleaner is highly effective for cleaning soffits, fascia, and cladding, and it leaves surfaces looking fresh without causing harm to the uPVC.
Both of these products work well due to their biodegradable nature and ability to target specific types of dirt and stains commonly found on exterior uPVC.
Removing Scuff Marks from uPVC
Our Ultimate Upvc cleaning guide covers cleaning high areas, but scuff marks are one of the most common types of stains on uPVC, especially on doors and windowsills. These marks are often caused by contact with shoes, furniture, or other objects. Fortunately, removing scuff marks from uPVC is relatively easy.
A magic sponge (melamine foam) is one of the most effective tools for removing scuff marks. When lightly dampened, it can lift scuff marks off uPVC without causing any damage. The abrasive texture of the sponge helps scrub away marks without scratching the surface.
Another useful product for removing scuff marks is The Pink Stuff. This mildly abrasive paste works similarly to T-Cut on cars, providing gentle abrasion to polish away scuff marks without harming the uPVC. Simply apply the paste, rub it in, and wipe it off to reveal a cleaner surface.
Cif is another popular brand for removing scuff marks. Its cream cleaner is mildly abrasive and works well for tougher stains or grime on uPVC surfaces.
Avoiding Strong Sodium Hypochlorite Mixes
One of the biggest mistakes people make when cleaning uPVC is using strong sodium hypochlorite mixes (bleach) on the surface. While bleach can effectively kill algae and mildew, it can also have disastrous effects on uPVC. Over time, using bleach or high concentrations of sodium hypochlorite can bleach the surface of the uPVC, causing it to turn yellow or discolour. This is especially true for white or light-coloured uPVC.
To avoid this, always opt for cleaners that are specifically designed for uPVC, and avoid overly strong chemicals that could cause discolouration. It’s best to use milder, non-caustic cleaners, such as Ubic or Virosol, which are both effective and safe for maintaining the integrity of the material.
Additional Tips for uPVC Care
- Regular Cleaning: To maintain the appearance of uPVC, regular cleaning is important. This can help prevent dirt and algae buildup, which can be harder to remove once it’s set in.
- Pressure Washing: For larger areas, such as soffits or fascia, using a pressure washer can be effective, but ensure you use a low-pressure setting to avoid damaging the uPVC.
- Avoid Abrasive Tools: While a magic sponge or mildly abrasive cleaner can help with scuff marks, always avoid using steel wool or harsh scrubbing brushes, as these can scratch and damage the surface
