Visual Guide: Cleaning Your Resin Sink
See examples of effective resin sink cleaning techniques, showing the transformation from stained to glossy with safe products and the right methods.
Step 1: Remove Surface Debris and Rinse
Start by removing any food scraps, loose debris, or surface dirt from the sink. Use warm water and a soft microfibre cloth to gently wipe down all visible areas. Make sure to reach corners and edges, where residue often accumulates. Avoid using abrasive pads which may cause scratches. Rinse the sink thoroughly to remove any loose particles before proceeding.
Step 2: Treat Stains and Grease
For greasy or stubborn stains, apply a small amount of Strong Technical Degreaser for Resin Projects – 100% Natural Formula directly to the problem areas. Let it sit for 2–5 minutes to allow the natural solvents to break down any buildup. Gently wipe with a non-abrasive sponge in circular motions. The natural formula is safe on resin surfaces and effective against grease, adhesive residues, and silicone marks, making it suitable for regular maintenance. Rinse off any cleaner thoroughly with warm water afterwards.
Step 3: Dissolve Residue and Sanitise the Surface
If water spots or lighter stains remain, dampen a clean microfibre cloth with Pure Isopropyl Alcohol 99.9% – 1000ml Bottle for Epoxy Resin Projects & DIY and wipe the affected areas. Isopropyl alcohol quickly evaporates to remove any sticky traces or residue without leaving streaks and is safe for resin when used in small amounts. Always ventilate the area and avoid excessive use. Allow the surface to air dry fully.
Step 4: Restore Gloss with Polishing
If your sink surface has become dull or has fine scratches even after cleaning, apply a small amount of “Epoxy Polish” – Epoxy Resin Polishing System following the kit’s instructions. Use a soft pad holder or polishing cloth in gentle, circular motions. This step removes fine blemishes and brings back the original shine of the resin without damaging the material. Wipe away any polishing residue with a clean cloth for a clear, glossy finish.
Tips, Common Mistakes, and Troubleshooting
- Always use non-abrasive cloths or soft sponges to prevent scratching the resin surface.
- Never use strong acids, bleach, or aggressive scrubbers as these can cause irreparable damage to resin sinks.
- Repeat degreasing or alcohol cleaning for tough stains, but allow the area to dry between treatments.
- Polish only once stains are removed for the best result; polishing over debris can create permanent marks.
- If staining persists after these steps, contact a professional for advice before attempting more intensive methods.
