Its penetrating action breaks down oil residues, wax, mold spores, and general surface soiling, leaving a clean substrate that promotes good adhesion for primers and antifoulants. Because it is water-based rather than petroleum-based, S-90 is safer to use and lifts stubborn contaminants with minimal scrubbing effort.\u003c\/p\u003e\u003cp\u003eS-90 is formulated without harsh chemicals and contains no methylene chloride, and it is water based and biodegradable. It can be used for general cleaning of virtually all surfaces, and is safe for cleaning painted surfaces when used properly. For general cleaning, apply generously with a cloth towel and gently rub to remove contaminants, then rinse away with clean water. For de-waxing with etch prior to coating, apply a thick wet coat using a china bristle brush or a solvent-resistant roller cover with 3\/8 inch nap, then work the surface with a Scotch-Brite 7447 pad in circular motions to create scratch\/profile ahead of primer or antifoulant application. Allow the product to work for 3-5 minutes before rinsing away with clean water.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea Hawk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e S-90GL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 811577012613\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Thinners \u0026amp; Solvents\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormula Type:\u003c\/strong\u003e Water-based de-waxing etch and cleaner, concentrated strength\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVOC Content:\u003c\/strong\u003e 316 grams\/liter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Application Method (De-Waxing):\u003c\/strong\u003e China bristle brush or solvent-resistant roller cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Roller Nap:\u003c\/strong\u003e 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Scrub Pad:\u003c\/strong\u003e Scotch-Brite 7447\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking\/Contact Time (De-Waxing with Etch):\u003c\/strong\u003e 3-5 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 7.55 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is Sea Hawk S-90 De-Waxing Etch \u0026amp; Cleaner used for?\u003c\/strong\u003e It is a water-based de-wax etch and cleaner designed to strip oil residues, wax, mold spores, and surface soiling from a hull before primer or antifoulant is applied, using S-90GL's concentrated formula for deep penetrating and lifting action.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs S-90 De-Waxing Etch \u0026amp; Cleaner water-based or solvent-based?\u003c\/strong\u003e Sea Hawk S-90 (part number S-90GL) is a water-based and biodegradable cleaner, which makes it safer to use than petroleum-based cleaning products while still cutting through grease and oil for scrub-free cleaning.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes S-90GL contain methylene chloride or harsh chemicals?\u003c\/strong\u003e No, Sea Hawk S-90 De-Waxing Etch \u0026amp; Cleaner is formulated with no harsh chemicals and contains no methylene chloride.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does a container of S-90GL weigh?\u003c\/strong\u003e Sea Hawk S-90 De-Waxing Etch \u0026amp; Cleaner (S-90GL) weighs 7.55 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I use S-90 for general cleaning versus de-waxing before painting?\u003c\/strong\u003e For general cleaning, apply S-90 generously with a cloth towel and gently rub to remove contaminants, then rinse with clean water.
