How to Clean Isinglass Curtains

Whether you run a center console or a sport-fisher with a flying bridge, odds are there is some sort of enclosure or curtain on your boat. If you don’t take care of the material that makes up the clear windows in the curtains, often referred to isinglass, the sun and salt will make quick work of the material and hamper your view.

Boat manufacturers use several types of clear plastic or vinyl for the windows of an enclosure. Some use a hard EZ2CY material while others use Strataglass or isinglass, which you can roll up. There are several other types, including a few brand new ones, but we have Strataglass on the Anyar and the Fish Trap.

To keep the Strataglass in good shape, I use two types of IMAR products ( made especially for the clear windows in the enclosure. The first is IMAR Strataglass Protective Cleaner and the second is IMAR Strataglass Protective Polish. To apply the products is a pretty simple process, but you want to be careful not to let anything scratch the material.

The first product we use is a protective polish. We apply this about once a month or whenever we get some stubborn dirt on the curtains (or bird droppings).

Rinse and dry the curtain with a chamois to make sure there is no grit or salt crystals on the material as these will scratch your windows.

Use a small microfiber application pad or soft terry cloth rag to clean the glass. Do small sections at a time.

Wax on the product, let it haze and then buff it off with a clean microfiber cloth.

For cleaning in between polishes we use an Imar spray cleaner. This is like the “Windex” for your plastic curtains. Just spray it on and buff off with a soft cloth.

To keep your plastic clean it is very important to dry it with a chamois after washing your boat. This eliminates the hard-water spots, which can become a real nuisance to remove from plastic and metal. If you keep up on the maintenance of your curtains, they should remain clean and clear for years to come.

Check out this simple tip to protect your curtains where they touch other surfaces.

Capt. Scott Goodwin started fishing in the lakes of Kentucky where he grew up. A move to Florida, however, brought him into a whole new realm of fishing. After receiving a bachelor's degree in biology from Eckerd College, he decided that he liked catching fish more than studying them and thus began his career as a captain. Scott began working as a mate on a charter boat and worked his way up to captain. He has been fortunate to fish in some of the top locations on the globe, including Florida, Panama, Costa Rica, Mexico and the Bahamas. Scott has learned from some of the best captains in the sport and has more than 25 years experience as a professional fisherman. He openly shares his knowledge and fishing tips on BD. Scott is currently the editor of BDOutdoors.
