General rules for canvas

Untreated cotton canvas is one of the most robust fabrics here and takes soaking, enzymes and firm handling.

The complications are the finish and the fittings. Waxed or proofed canvas loses its treatment in a detergent soak. Bags and shoes have leather trim, metal eyelets and glued seams that do not enjoy being submerged.

Work out which kind of canvas you have before deciding whether to soak it or treat only the mark.

Check the label

Canvas is a heavy plain weave, usually cotton, sometimes with a water repellent or waxed finish. Check for a finish before soaking anything, because water repellent treatments and wax are removed by detergent and are not easily put back.

Stains on canvas

Canvas is a plain, tightly woven cotton, thick enough to hold its own shape.

The weave is coarse

A heavy weave has larger gaps between yarns, so solids sit in them rather than on the surface. Scraping and rinsing from the back matter more on canvas than on a fine cotton.

Finishes change the rules

Water repellent, waxed and proofed canvas all shed their treatment in a detergent wash. That is recoverable with a re-proofing product, but it is an extra job and a cost.

It is usually attached to something else

Canvas shoes have rubber soles and glued seams, bags have leather trim and steel eyelets that rust. Soaking the whole item is often the wrong call even when the canvas itself would be fine.

It dries slowly

Thick cotton holds a lot of water. Drying it properly matters, because damp heavy cotton left folded goes musty and can mildew.
