Our Teak Brightener is supplied concentrated and can be mixed with water at a ratio of 1:1 to create 1 liter of ready to use, professional strength brightening solution. This product is needed for older, worn, grey and weathered teak. It will further enhance the natural beauty and color of all types of teak after using our Teak Cleaner. After cleaning, the brightener acts to lighten old, blemished teak, enhancing its overall appearance and preparing it for further treatment with Teak Oil as required. Teak Brightener will also remove rust marks, dark stains, and lighten darkened wood. If your teak is in good condition and/or only slightly weathered, then the cleaner alone should be sufficient. Regular cleaning and maintenance with Teak Brightener and our other teak products can help extend the life of your wooden surfaces and keep them looking good as new.
