Ondanks een goede dagelijkse routine ontstaan er soms hardnekkige stiftresten of vlekken die niet met een gewone veegbeurt verdwijnen. Dat is geen teken dat het whiteboard vervangen moet worden, maar meestal een signaal dat een andere aanpak nodig is. Deze stappen helpen om ook hardnekkige resten effectief te verwijderen zonder het oppervlak te beschadigen.

Hardnekkige stiftresten en vlekken van een schoolwhiteboard verwijderen: zo doe je dat
Waarom sommige resten hardnekkiger zijn dan andere
Stiftresten die langere tijd op het oppervlak hebben gezeten, of die zijn opgedroogd onder direct zonlicht, hechten zich sterker aan het oppervlak dan vers aangebrachte inkt, wat verklaart waarom een gewone veegbeurt niet altijd voldoende is.
De juiste eerste stap bij hardnekkige vlekken
Begin met een specifieke whiteboardreiniger in plaats van direct naar een sterker middel te grijpen, en laat de reiniger enkele minuten intrekken voordat u begint met vegen.
Wanneer een intensievere methode nodig is
Voor echt hardnekkige resten kan een zachte microvezeldoek met een klein beetje extra reiniger, gecombineerd met voorzichtige druk, vaak alsnog het gewenste resultaat geven zonder dat er krassen ontstaan.
Wat u beter kunt vermijden
Schuursponsjes, staalwol en agressieve chemische middelen lijken op korte termijn effectief, maar beschadigen de coating van het ceramic steel oppervlak, waardoor toekomstige vlekken zich juist makkelijker hechten.
Voorkomen is beter dan verwijderen
Regelmatig vegen, ook wanneer het oppervlak nog niet vol lijkt, voorkomt dat inkt de kans krijgt om langdurig in te drogen en daardoor hardnekkiger te worden.
