Convection Steam Oven Discoloration
- Inside of a Convection Steam Oven (CSO) is discoloring, brown, golden, or blue
- Dark stains stay in the CSO after use and cleaning is complete
- Black or brown spots inside walls of CSO
Discoloration in a Convection Steam Oven (CSO) may be because of several factors and varies by oven surface and stain type:
- Erratic, dark gray stains:
- Dark stains are from burned-in residue (especially spatters from meat and poultry), which may not get removed completely with cleaning.
- Cleaning with steam:
- When using the steam-only program (not combination of steam and hot air), some residue may clean off after steaming without use of any detergent.
- To soften residue, keep the door closed for 30 minutes after using the steam-only program, then clean the warm and humid cavity inside with a soft microfiber cloth.
- Leave the door opened for a while to allow the cavity to dry out.
- Refer to Convection Steam Oven Cleaning Information.
