Cleaning blind plastic discs

Plastic discs, whether made of acrylic glass (Plexiglas®) or polycarbonate, can become dull and cloudy over time due to scratches, deposits or UV exposure. This affects not only the appearance but also the function of the discs. However, there are simple ways to restore cloudy plastic discs to their former shine and breathe new life into them. In this article you will learn how to clean, polish and care for your dull plastic discs in order to maintain a clear view.

Causes of cloudy plastic discs

Cloudy plastic discs are caused by various influences. The most common causes include:

• Scratches and micro-scratches: Caused by improper cleaning or mechanical stress.
• UV exposure: Long-term sunlight can lead to yellowing and clouding.
• Soiling: Dust, pollen and dirt particles settle and leave dull surfaces.

For the discs to look like new again, the right cleaning and care is crucial.

Cleaning steps for cloudy plastic discs such as acrylic sheets

1. Preparation and basic cleaning

First, the basic cleaning of the plastic discs should be carried out to remove surface dirt. Use lukewarm water and a soft microfibre cloth for this. Avoid hard sponges or abrasive cleaning agents, as these can cause scratches.

• Prepare the mixture: Add a few drops of mild washing-up liquid to lukewarm water.
• Wipe the discs: Dip the microfibre cloth into the mixture and carefully wipe the discs. Make sure that no coarse particles remain on the disc in order to avoid further scratches.

2. Polishing for more shine

To remove deeper scratches and the clouding, the plastic discs should be polished. A special polishing paste for plastic surfaces is suitable for this. This is available from DIY stores or specialist retailers.

• Apply polishing paste: Apply a small amount of polishing paste to a clean microfibre cloth or a soft polishing pad.
• Polish: Polish the disc with light pressure in circular movements. Always work in small sections and take enough time to achieve even results.
• Remove residues: Remove residues of the polish with a fresh microfibre cloth and check the result. Repeat the process if necessary until the desired clarity is achieved.

3. Protecting the surface

To protect the plastic discs after cleaning and polishing, it is advisable to apply a sealant. This protects the surface from new scratches and reduces the adhesion of dirt.

• Apply sealant: Use a special plastic sealant or a suitable plastic protectant. Apply the sealant to the cleaned and polished surface in accordance with the manufacturer's instructions.
• Work it in: Work the sealant in with a soft cloth and then allow it to dry. This protective layer ensures that the discs stay clear for longer and are easier to clean in future.

Important tips for caring for plastic discs

• Avoid aggressive cleaning agents: Avoid using aggressive cleaners such as acetone or alcohol, as these can attack the surface and make it dull.
• Do not use scouring sponges: Only use soft cloths to avoid scratches.
• Regular care: Carry out regular cleaning to prevent stubborn soiling and the formation of scratches.
