Why Golden Care teak protector is so much better than teak-oil/sealer: it maintains the golden-brown color of teak for a longer time. Teak-oil often causes black spots on teak. Our protector prevents black spots. Our teak protector is not an oil and it is not greasy, so clothes stay clean. Most teak-oils/sealers contain hazardous solvents/VOC's. Our protector is completely water-based and Solvent-free: that is why we call it ecosafe.
