How you go about removing the rust will partially depend on the canvas item. If it is a canvas cover, you can move it around in ways that you won’t be able to move a canvas beach chair, where the canvas covering permanently attaches to the chair.
Things You Will Need
-
Cover the rust stain with table salt.
-
Pour lemon juice over the salt to make a paste.
-
Set the canvas in the sun, or soak the area in a pint of warm water.
-
Rinse off the canvas after the rust disappears.
The Drip Cap
- Acids remove rust stains from canvas.
- Instead of using a poisonous substance, like oxalic acid, another option is lemon juice, which is both acid and edible.
- Cover the rust stain with table salt.
