Spring is here once again and it is time to get that metal, outdoor furniture and all those Bar-B-Q Grill looking spiffy again before your guests start arriving. The hardest part of that process has always been the rust removal which must be done before

Naval Jelly, the miracle rust remover, has been around for over twenty-five years, yet most DIY people are unaware of it and continue to remove rust the old fashion way with scrapers, wire brushes, and sandpaper. Naval Jelly, a pretty, pink gel, is really available at any hardware store or home center. You need to have this wonder working chemical in your shops chemical cabinet right next to those cans of Specialty WD-40 Products.

What is Naval Jelly?

Today, Naval Jelly is manufactured by the Loctite Corporation and sold as LOCTITE® NAVAL JELLY RUST DISOLVER. Naval Jelly does contain Phosphoric Acid (10 to 30 percent by composition) and minute amounts of Sulfuric Acid (0.1 to 1.0 percent by composition), as well as other hazardous chemicals—Phosphate ester (1 to 5 percent), Polysaccharide (1 to 5 percent), and Isopropyl alcohol (1 to 5 percent). Water makes up the non-hazardous portion by more than 50 percent.

Safety precaution to be observed when using Naval Jelly

  • Do not use in confined spaces. Use Naval Jelly in well ventilated areas only. Inhaling the fumes can seriously damage your respiratory system.

  • Always wear rubber or plastic gloves when working with naval Jelly. If you do get some on your skin, wash it off immediately using plenty of soap and water.

  • Always wear safety glasses, safety goggles, or a full-face shield to prevent the Naval Jelly from getting into your eyes. If you do get any in your eyes, wash your eyes out with plenty of water for at least fifteen minutes and then see a doctor immediately.

  • If you swallow any Naval jelly, do not induce vomiting, but drink large amounts of water and head for the ER.

  • By now it should be obvious that this is a product that you need to keep out of the reach of children and pets. There should be no children allowed in the area where you are working with Naval Jelly.

  • Do not dispose of Naval Jelly by flushing it down the drain.

I did not put all this first to scare you away from using this product, but, as I said in my article, “The 4 Cardinal Rules of DIY”, safety first, always safety first. Naval jelly can be used safely as long as you know what safety pecautions you need to take when using it.
