Identify the sink material and spill
Check the sink or vanity maker's care guidance and distinguish surface residue from etching, scratches or a finish change. Remove loose product without spreading it and avoid scraping the basin.
Start with a gentle compatible method
If the care instructions permit, use a soft cloth and mild labelled cleaner for the surface. Blot or wipe gently, rinse only as directed and dry the area. Test an unfamiliar product discreetly and stop if colour, shine or texture changes.
Avoid acids, abrasive powders and long soaking
Vinegar, lemon, baking soda, bleach and scouring pads may damage some stone, grout, coatings and acrylic. Do not leave a chemical on the sink overnight or mix products. Follow the exact cleaner label and material guidance.
When the mark does not lift
A permanent dye mark, etching or finish damage may not be removable by cleaning. Avoid escalating to stronger chemicals; ask the sink maker or a qualified surface specialist for advice.
