Simmered Sodium Bicarbonate Soak for Scorched Enameled Cast Iron Cookware
Rex says
Rex Sterling, Ph.D. · Head of R&D, Clean Report · Meet Rex
"Simmering 2 tablespoons of baking soda in water inside a burnt Dutch oven or enamel pan for 10 minutes releases charred food fond without scratching the enamel glaze."
The science
-
Alkali does it, not abrasion
Sodium bicarbonate dissolves to a mildly alkaline solution and, on heating, drives off CO2 toward carbonate, pushing pH higher as it simmers. That alkalinity hydrolyzes scorched protein and starch and saponifies burnt fat, so the fond swells, loses grip on the glaze, and releases under a soft tool.
-
Enamel is glass; it minds scratches, not pH
Vitreous enamel is a fused glass coating and shrugs off mild alkali at simmering temperatures. Its real failure modes are mechanical - metal scrapers, scouring powder, chipping - plus thermal shock. A bicarbonate soak attacks the soil while leaving the only vulnerable thing, the surface itself, alone.
-
Carbon that is truly charred will not dissolve
Bicarbonate loosens cooked-on food; it does not dissolve hard carbonized crust or the brown staining that builds inside pale interiors. Expect two or three soaks for a bad burn. If a soak stops making progress, that is the ceiling - escalate to a dedicated enamel cleaner, not to steel wool.
Do it right
Cover the burnt area with water, add about 2 tablespoons of baking soda, simmer gently for 10 minutes, then let it cool and lift the residue with a wooden or nylon tool. Repeat the soak rather than reaching for a scouring pad, and never pour cold water into a hot pan.
