If necessary, carefully treat the headlamps with Headlight Polish (Art. No. 02761410). Open a sachet, pour onto a SONAX Polishing Cloth (Art. No. 04222000) and apply a thin layer to the clean and dry headlamp. One sachet is intended for the treatment of two headlamps. Do not use on glass or hot surfaces. Immediately wipe off residue with a SONAX Microfibre Cloth soft touch (04510000). Allow product to harden at least 4 hours; make sure the vehicle does not get wet during this time. Do not wash the vehicle within 1 week after application.
