BEWARE OF OIL-BASED PRODUCTSGolden Care products are water-based. Water transports active ingredients into the hardwood, then the water evaporates, leaving the wood residue-free. Oil-based products are for indoor woods only. In teak and other hardwoods, the oil seeps into cracks and does not evaporate, resulting in mold and mildew. The results from Golden Care products last 3-4 times longer. The world's top teak and hardwood manufacturers use Golden Care products in their factories.
