Sundries for cleaning your polytunnel

🧼 How to Clean Your Polytunnel

Cleaning is straightforward:

  1. Spray Agri Clear Pro onto the polythene using a pressure sprayer.

  2. Leave it to work — no scrubbing or rinsing required.

  3. The solution continues breaking down dirt and growth over time, restoring clarity and light transmission.

💧 Controlling Condensation

Treating the inside of your polytunnel every two to five years with Sun Clear helps prevent condensation build‑up. This keeps the interior brighter, reduces dripping, and improves overall growing conditions.

🌿 AlgiclearPro Green Algae Remover – Super Concentrate

Long‑term control for algae, moss, liverwort & lichens

AlgiclearPro is a highly concentrated, environmentally sensitive treatment designed to kill and prevent algae, moss, liverwort and lichens on all hard surfaces. Using patented technology, Algiclear lifts and encapsulates the algal cell, causing it to dry out and simply blow away.

This twin‑effect formula provides immediate cleaning and residual protection for up to 9 months, helping keep surfaces clear long after application.

Powerful protection with a safer, grower‑friendly formula

Hortisept Pro is a specially formulated synergistic disinfectant blend that delivers broad‑spectrum protection while remaining user‑safe and environmentally sensitive. Effective against bacteria, fungi, and viruses, it provides reliable hygiene for polytunnels, greenhouses, propagation areas, and equipment.

Why Growers Choose Hortisept Pro

  • Bactericidal, fungicidal & virucidal performance

  • Non‑corrosive and low‑risk for users and the environment

🌿 Polytex Pro – Polytunnel & PVC Cleaning Solution

Green residue on your polytunnel cover can significantly reduce light transmission, limiting plant growth and reducing overall efficiency. This build‑up often comes from nearby trees and general environmental exposure. Importantly, soapy water should never be used, as it reacts negatively with the oil‑based polymers in polytunnel plastic.

Polytex Pro is the only cleaner we recommend. It has been specifically developed for the safe and effective cleaning of polythene, plastics, and uPVC — making it ideal for polytunnels, conservatories, and window frames. 

🧴 Application Rates

  • Dilution: Mix 1:10 with water

  • Suitable for manual cleaning, machine application, or power hose use

  • For best results, apply and then rub with a soft broom or cloth shortly afterwards

📏 Coverage

  • 1 litre covers approx. 110m² (e.g., a 14ft × 45ft polytunnel)

  • 5 litres covers approx. 550m² (e.g., two 21ft × 80ft polytunnels)

🌿 How It Works

Once applied, water condenses into a thin, continuous film rather than forming droplets. This film then runs down the curved sheeting to the outer edges of the structure, keeping the interior clear and drip‑free.

🏡 Suitable for Multiple Greenhouse Plastics

Sunclear can be used on:

  • UVI polythene

  • PVC

  • Polyester sheeting

  • Flexible or rigid plastics used in greenhouse construction

Although developed for polytunnels, it performs equally well in glasshouses and other covered growing environments.

⭐ Key Benefits

  • Up to 15% more light transmitted

  • Non‑toxic and safe for use around plants and food crops

  • Easy application — spray or paint on

  • Eliminates dripping, helping reduce fungal diseases such as Botrytis

📏 Coverage

One 473ml container covers up to 900m² (9,500ft²) — approximately a 21ft × 100ft polytunnel.
