How to Remove Watermarks and Streaks from a Resin Shower Tray

← Back to How do you clean a resin shower tray?

Noticed watermarks or streaks developing on your resin shower tray? These smudges can be both unsightly and stubborn, but with a careful approach and the right supplies, you can restore your tray’s original clarity and shine.

Step-by-Step: Preventing and Removing Watermarks

Routine drying is key to avoiding residue. After each use or cleaning, wipe the tray thoroughly with a soft microfibre cloth. Microfibre is gentle on resin and highly absorbent, effectively lifting away water to prevent streak formation.

Go over the tray in overlapping motions to collect all moisture.
Pay special attention to any pooling areas or edges where water may linger.

For existing watermarks, dampen the cloth slightly before buffing to help loosen mineral build-up. Always finish by drying with a fresh, dry section of the cloth.

Dealing with Stubborn Marks and Greasy Residues

If regular drying isn’t enough, a gentle cleaning product can help. Apply a non-abrasive, naturally formulated cleaner such as the Strong Technical Degreaser for Resin Projects to target oily or sticky residues without harming the resin. Simply apply a small amount to a damp microfibre cloth, wipe the affected area, then rinse and dry as normal.

When Polishing Makes a Difference

If you notice persistent dullness or fine streaking, a polishing product specifically designed for resin – like the “Epoxy Polish” – Epoxy Resin Polishing System – can restore gloss. Always use with appropriate soft cloths or pads, and follow product instructions for safest results.

When This Matters Most

Watermarks and streaks are most visible in bright bathrooms and on darker trays. Regular attention helps maintain a lasting, spotless finish – especially important before guests arrive or during seasonal home cleaning.
