How to Clean Oven Racks: The Bathtub Soak, Baking Soda and What Scratches
Greasy oven racks come clean with a long hot-water soak, a little dish soap and a baking soda scrub. Here is the method, the dryer sheet question, and how to keep racks sliding smoothly.
The simplest way to clean oven racks is to soak them for several hours in very hot water with dish soap (a bathtub, laundry sink or large tub works), then scrub with a baking soda paste and a non-scratch or nylon brush, rinse and dry. Most oven makers say to take racks out before a self-clean cycle, because the extreme heat can discolor shiny racks and make them stick. Line the tub with an old towel so the metal does not scratch it.
Racks collect drips from every roast and casserole, and the grease polymerizes into a sticky brown layer that ordinary washing barely touches. Time and heat do most of the work here, so plan the job for an evening and let it soak overnight.
What you need
- A bathtub, utility sink, large plastic storage tub or a heavy-duty trash bag
- An old towel to protect the tub surface
- Hot water and a generous squirt of dish soap
- Baking soda
- A nylon scrub brush, non-scratch sponge or old toothbrush
- Rubber gloves
- Vegetable oil (for the rack slides afterward, if they stick)
Step-by-step: the hot soak method
- Let the oven cool and pull the racks out.
- Protect the tub. Lay an old towel in the bottom so the metal edges do not chip or scratch enamel or acrylic.
- Fill with hot water deep enough to cover the racks and add dish soap. Swish to dissolve.
- Soak several hours or overnight. Longer soaks make a real difference on old, sticky grease.
- Scrub. Make a paste of baking soda and a little water, rub it along the bars with the brush, and work the corners where bars meet the frame.
- Rinse well with clean water so no soap or soda residue bakes on later.
- Dry completely with a towel before putting them back.
- Clean the tub right away so greasy water does not leave a ring.
No tub to spare? Put each rack in a heavy-duty trash bag with hot soapy water, tie it closed and lay it flat in a sink or on the lawn overnight, then scrub and rinse.
Do dryer sheets help?
A popular trick is soaking racks with a few dryer sheets in the water. Some people report it helps, but there is no manufacturer guidance or published research behind it, and dryer sheets add fragrance and softener residue you then have to rinse off. Dish soap is designed to cut grease, is cheaper and leaves nothing behind after rinsing. If you already have dryer sheets and want to try them, rinse the racks very thoroughly afterward.
What works and what damages racks
| Approach | Verdict | Notes |
|---|---|---|
| Hot water, dish soap, long soak | Safe, effective | The first thing to try |
| Baking soda paste with nylon brush | Safe, effective | Mild abrasive; good for sticky spots |
| Steel wool | Use with care | Some manufacturers suggest it for plain chrome racks; avoid on coated or enameled racks and on rack glides |
| Commercial oven cleaner | Possible, with caution | Caustic; follow the label, use outdoors or with strong ventilation, gloves and eye protection, rinse thoroughly |
| Self-clean cycle with racks in | Usually no | Only for racks your manual says can stay in; others may discolor or stop sliding |
| Dishwasher | Usually no | Racks rarely fit and baked grease will not shift; check your manual |
Self-clean and your racks
Manufacturer instructions vary. Whirlpool’s product help says to always remove oven racks before self-cleaning, while some GE manuals say the dark enameled racks supplied with that oven can stay in and only shiny racks must come out. Some Samsung guidance says porcelain-coated racks can remain but nickel racks should be removed. In short: your manual decides. If you do not have it, search the model number on the maker’s support site.
Racks left in the cycle that were not designed for it often come out with a dull or rainbow discoloration and can be harder to slide. That is mostly cosmetic, but it is easy to avoid. For the full oven cleaning process, see our guide to how to clean an oven.
Racks with ball-bearing glides
Extension racks with telescoping glides need gentler treatment. Long soaks can wash out the lubricant that keeps them rolling, so wipe the glides instead of submerging them where possible, and keep them out of self-clean unless the manual says otherwise. Clean the wire part with soapy water and a brush, and dry the glides thoroughly.
If racks stick after cleaning
Clean racks can drag on the side supports. Whirlpool and GE both suggest a light coat of vegetable oil on the rack guides or supports. GE notes that other cooking oils can leave a discolored residue, so stick with a thin film of vegetable oil wiped on with a paper towel.
Using oven cleaner safely, if you choose to
- Read the whole label first and use only that one product; do not combine it with any other cleaner, and never with bleach.
- Work outdoors or in a well-ventilated space, with gloves and eye protection.
- Place racks on newspaper or in a trash bag, spray, wait the label time, then rinse thoroughly with a hose or in the tub.
- Keep the can in its original container, away from children and pets.
If someone swallows, inhales or gets a cleaning product in the eyes, call Poison Control at 1-800-222-1222 (US) or emergency services.
Keeping racks cleaner
- Put a sheet pan under dishes that may bubble over.
- Wipe drips once the oven cools, before they bake on again.
- Give racks a quick soapy wash every month or two so grease never builds up into a hard layer.
Roasting pans tend to need cleaning at the same time; our guide to cleaning a roasting pan covers soaking by material.
Bottom line
A long hot soak with dish soap, followed by a baking soda scrub, cleans most oven racks for almost nothing. Protect the tub with a towel, rinse well, and check your manual before leaving racks in a self-clean cycle. A little vegetable oil on the supports fixes sticky racks.
FAQ
How long should I soak oven racks?
At least a few hours, and overnight for heavy grease. The hotter the starting water, the better.
Can I clean oven racks in the self-clean cycle?
Only if your manual says your rack type can stay in. Many makers say to remove all racks; others allow specific coated or enameled racks.
Will baking soda scratch the racks?
Baking soda is a mild abrasive and is generally safe on chrome-plated and enameled racks when used with a nylon brush. Steel wool and gritty powders are much more likely to scratch.
Why are my racks hard to slide after cleaning?
Cleaning removes the grease film that was acting as a lubricant. Wipe a thin coat of vegetable oil onto the rack supports.
