How to Remove Old Stains from a Resin Chair

Stubborn marks and discolouration can spoil the appearance of resin chairs, but with the right methods it’s often possible to restore their original look. Here’s how you can tackle old stains safely and prepare your chair for any further repairs or refinishing.

Choosing the Right Cleaning Approach

Before reaching for harsh chemicals, start by removing surface dirt with warm soapy water. For persistent stains, a specialist cleaner like the Strong Technical Degreaser for Resin Projects works particularly well on resin. Formulated with natural plant extracts, it helps dissolve grease, marker ink, and silicone residues without damaging resin surfaces or leaving harmful residues.

Applying Gentle Abrasion

If stains prove resistant, consider gentle mechanical cleaning. Use a soft cloth or non-abrasive pad and work with mild pressure. For ingrained spots, a touch of fine polishing compound—such as the “Epoxy Polish” system—can help lift grimy patches and restore shine. Always test your chosen method in an inconspicuous area to ensure no dullness or scratching occurs.

When Stain Removal Matters

Effective cleaning is essential before attempting any resin repair or refinishing. Removing old stains ensures that adhesion is not compromised and gives repairs a more seamless finish.
Regular cleaning makes ongoing maintenance quicker and protects the look of the chair long-term.
