As an engineered quartz, 9211 Taj Mahal Genius is virtually non-porous and needs no classic natural stone sealer. Daily cleaning is with warm water, a soft microfibre cloth and a mild, pH-neutral general-purpose cleaner. Afterwards wipe over with clear water and polish dry — otherwise wiping streaks remain visible as a veil on the pale, warm cream tonality.
Do not use: aggressive solvents, abrasive pads, strongly alkaline cleaners and acidic specialist cleaners (descalers based on phosphoric or hydrochloric acid, alloy wheel cleaners, oven sprays). These can attack the polyester resin matrix and leave matt patches.
Kitchen and bathroom: take up spilt food, wine, coffee or oil promptly with warm water and mild washing-up liquid — the surface is stain-resistant, but dark pigments can leave a veil if allowed to act for a long time. Do not set hot pots down directly from the hob — engineered quartz is heat-resistant in everyday use, but very high temperatures above 150 °C can locally damage the resin matrix. Use trivets or a chopping board.
For external applications, engineered quartz is suitable only to a limited extent — direct UV exposure can alter the pigments and the resin matrix over the long term. Recommendation: internal applications or covered external surfaces.
Scratches and repair: in the case of mechanical damage or local matt patches, a specialist engineered quartz fabricator can locally repolish the surface or make it good with colour-matched repair pastes.
