uPVC cleaning vs other exterior cleaning methods

There are several methods used to bring uPVC back to its best. Here’s a quick overview of the popular options:

uPVC cleaning

• Gentle detergents or non-abrasive cleaners
• Designed to protect surface coatings
• Suitable for frames, sills, fascias, and gutter fronts

Pressure washing

• Effective for some exteriors
• Not always suitable for uPVC close to seals or vents

Hand detailing or restoration products

• Can help remove oxidation when appropriate
• More time-intensive

How long does uPVC cleaning take?

Timescales for uPVC cleaning vary depending on surface size and access:

• Small sets of windows: 30–60 minutes

Can discoloured or faded uPVC be restored?

Surface-level staining on uPVC can often be improved through specialist cleaning, non-abrasive pads, or approved uPVC restoring products.

However, deeply faded or sun-damaged uPVC may not return to its original appearance and may require repair or replacement of the affected sections.
