IOSSO Decap-Out Gel
Professional IOSSO Decap-Out Gel, a powerful acidic descaler designed to remove stubborn marine growth, limescale, and oxidation. Its high-adhesion gel formula stays in place on vertical surfaces, making it the perfect tool for cleaning boat hulls, waterlines, propellers, and stainless steel hardware. Safe for fiberglass (GRP), PVC, and acid-resistant metals.
IOSSO Decap-Out Gel is engineered for “restoration” level cleaning. In the nautical world, the waterline and hull often accumulate a “beard” of calcium deposits and biological growth that standard soaps cannot touch. Decap-Out Gel chemically dissolves these mineral bonds.
The standout feature of this product is its Gel Technology. When applied to a vertical hull or a hanging propeller, the gel remains thick and active, preventing runoff and ensuring the acid stays in contact with the encrustation for the required dwell time. It is also exceptionally effective at removing “rust bleeds” from stainless steel fittings and yellowing from fiberglass. Once the gel has finished its work, it can be easily rinsed away with fresh water, leaving a surgically clean surface ready for polishing or anti-fouling.
✔ High-Adhesion Gel → Stay-put formula for vertical and overhead applications.
✔ Mineral Dissolver → Instantly attacks limescale, salt crusts, and barnacle bases.
✔ Biological Remediation → Breaks down algae and organic residues on the hull.
✔ Rust & Oxidation Eraser → Removes surface rust from Inox and oxidation from aluminum.
✔ Concentrated Power → Reduces product waste by allowing targeted application.
✔ Fiberglass Safe → Specifically tested for use on marine gelcoats and GRP.
✅ Fiberglass (GRP): For waterline cleaning and yellowing removal.
✅ Stainless Steel: Removing tea-staining and rust spots.
✅ Aluminum: Removing heavy oxidation (test on a small area first).
✅ Ceramic & PVC: Ideal for head (toilet) systems and rigid fenders.
✅ Acid-Resistant Paints: For industrial and technical cleaning.
🔹 Application Instructions
Preparation: Ensure the surface is dry to prevent diluting the gel.
Apply: Brush or sponge the pure gel onto the encrusted area.
Dwell: Leave it to act for 5–15 minutes. For very thick barnacle bases, you may leave it slightly longer, but do not let it dry completely.
Agitate: Use a stiff plastic brush or a non-abrasive pad to help break up the loosened deposits.
Rinse: Flush with plenty of fresh water.
👉 Pro Tip: In the nautical sector, use Decap-Out Gel to clean propellers and shafts after hauling the boat out. It dissolves the “white ring” calcium deposits that often remain even after pressure washing, ensuring your running gear is perfectly smooth for the next season.
Hulls & Waterlines: Removing the “yellow stain” and calcium buildup.
Propulsion Gear: Cleaning propellers, rudders, and trim tabs.
Engine Cooling Systems: Descaling heat exchangers (external parts).
Sanitary Systems: Removing heavy limescale from marine toilets and pipes.
Metal Restoration: Cleaning rusted stainless steel railings and cleats.
Decap-Out Gel: Ready-to-use professional gel formula.
A surface completely free of mineral and biological encrustations, restored to its original smoothness and ready for protective coatings or aesthetic finishing.
