Household detergents glide over it, scrubbing only spreads the film. Universal FUGEX cuts through that mortar residue in minutes and rinses away without etching the tile surface.\u003c\/p\u003e\n\u003ch2\u003eWhat FUGEX Does\u003c\/h2\u003e\n\u003cp\u003eFUGEX is an alkaline gel cleaner for ceramic, porcelain, and other acid-sensitive surfaces. With a pH of 11.5 it breaks the cementitious bond in joint mortar residues while surfactants lift greasy dirt. The thixotropic gel (viscosity 4,500 mPa·s) clings to vertical joints, giving the active ingredients a 3-minute window to dissolve particles up to 50 µm thick.\u003c\/p\u003e\n\u003ch2\u003eWhen to Use\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFresh mortar haze on patio \u003ca href=\"\/en-hr\/pages\/stone-porcelain\"\u003eporcelain\u003c\/a\u003e: dilute 1 : 10.\u003c\/li\u003e\n\u003cli\u003eEpoxy streaks on indoor \u003ca href=\"\/en-hr\/pages\/stone-ceramic\"\u003eceramic\u003c\/a\u003e shower walls: use 1 : 5.\u003c\/li\u003e\n\u003cli\u003eDeep-set grime in textured \u003ca href=\"\/en-hr\/pages\/stone-granite\"\u003egranite\u003c\/a\u003e kitchen flooring: 1 : 5.\u003c\/li\u003e\n\u003cli\u003eChalky runoff on balcony \u003ca href=\"\/en-hr\/pages\/stone-concrete\"\u003econcrete\u003c\/a\u003e pavers after winter: 1 : 10.\u003c\/li\u003e\n\u003cli\u003eAnnual spring \u003ca href=\"\/en-hr\/pages\/problem-outdoor-cleaning\"\u003eoutdoor cleaning\u003c\/a\u003e routine for clinker steps: 1 : 10.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to Apply\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003ePrepare a 1 : 5 or 1 : 10 solution in a bucket and wet the surface.
