The quick answer
Before you paint kitchen cabinets, you need to remove grease, hand oils, cooking residue, and surface shine. A quick wipe-down is not enough.
My go-to first step is Cabinet Prep because it is made for the exact problem cabinet painters run into: cabinets that look clean but are still too greasy, glossy, or contaminated for the next coating to bond well.
Here’s the simple order:
- Protect the area and remove obvious dust or debris.
- Spray Cabinet Prep onto the cabinet surface.
- Wipe thoroughly with a clean cloth or scrub pad.
- Let it sit briefly on heavy grease, then wipe clean.
- Let the cabinets dry fully.
- Move on to sanding, grain filling, primer, or paint.
The biggest thing to remember is this: cleaning and deglossing comes before Cabinet Mud, primer, or paint.
Cabinet Prep
Degreaser + deglosser made for cabinets, so primer, Cabinet Mud, and paint can actually bond.
- Breaks through kitchen grease, grime, and hand oils
- Dulls slick cabinet surfaces for better adhesion
- Leaves no waxy or oily residue behind
- No rinsing required
- One 16 oz bottle preps most average-size kitchens
Why cleaning cabinets before painting matters so much
Most cabinet painting problems start before the paint ever goes on.
Kitchen cabinets live in one of the worst environments for paint adhesion. They collect cooking grease, hand oils, food residue, old cleaners, polish, dust, and everyday grime. The worst areas are usually around handles and pulls, near the stove, around the sink, and along the edges of doors and drawer fronts.
The tricky part is that cabinets can look clean and still be a bad surface for primer or paint.
If the surface is greasy or glossy, the paint system is already fighting uphill.
That is why I want the cabinets clean and deglossed before I sand, fill grain, prime, or paint. This step makes the rest of the project more predictable.
What should you use to clean cabinets before painting?
I like using Cabinet Prep because it handles both parts of this stage: cleaning and deglossing.
That matters because you are not just trying to remove visible dirt. You are trying to remove the stuff that can stop the next layer from bonding.
Degrease
Remove kitchen grease, cooking residue, grime, and hand oils that build up over time.
Dull the gloss
Break down slick surface shine so Cabinet Mud, primer, and paint are not trying to bond to a shiny surface.
Move on clean
Let the surface dry fully, then continue with sanding, grain filling, primer, or paint.
How to clean kitchen cabinets before painting: step by step
Here is the exact cleaning flow I would use before painting cabinets.
Step 1: Protect the area
Before you start spraying or wiping anything, protect the areas around your cabinets. Put down drop cloths or plastic where needed, move small appliances, and clear off the counters.
You do not need to make this complicated, but you do want to avoid dripping cleaner onto things you care about.
Step 2: Remove hardware or clean around it carefully
If you are doing a full cabinet painting project, remove the knobs, pulls, and hinges and label everything. If you are still in the early prep stage, at least pay special attention around every handle and pull.
Those spots usually have the most hand oils and grime.
Step 3: Knock off loose dust and crumbs first
Use a vacuum, soft brush, or dry cloth to remove loose dust, crumbs, pet hair, and debris before wet cleaning.
This keeps you from just smearing loose junk around the surface.
Step 4: Spray Cabinet Prep onto the cabinet surface
Work in manageable sections. Spray Cabinet Prep onto the cabinet surface, then wipe thoroughly with a clean cloth or scrub pad.
On heavier grease areas, let it sit briefly before wiping. Around the stove, near handles, and on drawer fronts, do not be afraid to scrub a little.
Step 5: Change cloths as they get dirty
This is a small detail that makes a big difference.
If your cloth is picking up grease and grime, do not keep wiping the whole kitchen with the same dirty towel. Switch to a clean cloth as needed so you are actually removing contamination instead of spreading it around.
Step 6: Let the cabinets dry fully
After wiping, let the surface dry fully before you move on.
You want the cabinets to feel clean and dull, not slick, greasy, wet, or tacky.
Step 7: Inspect the problem areas and repeat if needed
Look closely around handles, edges, the stove area, and any doors that still feel slick. If something still feels greasy or shiny, clean it again.
It is much easier to repeat cleaning now than to fix peeling paint later.
Important: Cabinet Prep does not replace sanding
Cabinet Prep cleans and deglosses. Sanding handles texture, roughness, and surface refinement. For the best cabinet painting process, use both in the right order.
Clean and degloss first. Then sand. Then remove dust. Then move on to Cabinet Mud, primer, or paint.
Cabinet Prep vs. dish soap, TSP, and other cleaners
There are a lot of ways people try to clean cabinets before painting. Some can work in certain situations, but I prefer Cabinet Prep because it is built specifically for cabinet painting prep.
| Cleaning Method | What it does well | Where it falls short | My take |
|---|---|---|---|
| Dish soap and water | Good for basic surface dirt and light kitchen grime. | It does not properly degloss cabinet surfaces and can leave you with extra rinsing/drying steps. | Fine for general cleaning, but not my first choice for cabinet paint prep. |
| TSP | Strong cleaner that many painters have used for years. | Can be harsh, usually requires careful rinsing, and residue can create problems if not handled correctly. | It can clean, but it adds more risk and cleanup than most DIYers need. |
| General household degreaser | Can help cut grease in normal household cleaning situations. | Not all degreasers are designed for adhesion prep, and some may leave residue depending on the product. | Read the label carefully. I would rather use something made for cabinet painting. |
| Liquid sandpaper / deglosser | Can dull gloss on some surfaces. | Not always a complete grease-removal solution, and some products have stronger fumes or timing requirements. | Deglossing alone is not enough if grease and oils are still there. |
| Cabinet Prep | Degreases, deglosses, leaves no waxy/oily residue, and does not require rinsing. | You still need to sand after cleaning as part of a proper cabinet process. | This is the simplest first step for most cabinet painting projects. |
Why Cabinet Prep wins for most DIY cabinet jobs
Cabinet Prep is not just a random cleaner. It is a cabinet-painting prep product. It is made for vertical cabinet surfaces, hidden grease, hand oils, cooking residue, and slick finish that can stop the next layer from grabbing.
The areas you should clean twice
Some parts of the kitchen always need extra attention. If I were only going to tell you to slow down in a few places, it would be these:
Around handles and pulls
This is where hand oils build up the most. Don’t just wipe the face of the door and miss the edges around the hardware.
Near the stove
Grease can travel farther than people think. Upper cabinets and doors near the stove often need extra cleaning.
Drawer fronts
Drawers get touched constantly, especially around utensil drawers, trash pullouts, and sink areas.
Edges, rails, and profiles
Grime can hide in profiles and corners. Work the cleaner into those details instead of only wiping the flat center panel.
What comes after cleaning?
Once the cabinets are clean, dry, and dull, you can move into the rest of the cabinet painting process.
The next step depends on your cabinet type and finish goal.
Sanding
Cabinet Prep does not replace sanding. After cleaning, sand the surface, then remove dust before filler, primer, or paint.
Grain filling
If you have oak cabinets and want a smoother painted finish, clean first, then fill the grain with Cabinet Mud before primer.
Kits
Want the supplies grouped by stage? Use a kit so you are not piecing the whole cabinet project together one product at a time.
Clean first. Then fix the grain.
If you are painting oak and want a smoother finish, cleaning is only the first step. Once the cabinets are clean and dry, use Cabinet Mud or the Oak Cabinet Grain Filler Kit before primer.
Common cabinet cleaning mistakes before painting
These are the mistakes I would avoid if you want the rest of the project to go smoother.
1. Only wiping the middle of the door
The worst grease is usually around handles, edges, and profiles. Clean the entire door, not just the easy flat areas.
2. Using a dirty rag too long
Once a cloth is loaded with grease and grime, switch to a clean one. Otherwise, you are just moving residue around.
3. Skipping deglossing
Cabinets can be clean and still too slick. That surface shine needs to be dulled before the next steps.
4. Thinking cleaning replaces sanding
It does not. Cleaning/deglossing and sanding do different jobs. Use both.
5. Not letting the surface dry
Do not trap moisture under sanding dust, filler, primer, or paint. Let the cabinets dry fully.
6. Waiting until after sanding to degrease
Clean first so grease and grime do not get pushed around or ground into the surface during sanding.
What I’d buy first
If you are starting a cabinet painting project and want the step that makes the rest of the system work better, start with Cabinet Prep.
Cabinet Prep
Use this before Cabinet Mud, primer, or paint. It is the cleaning and deglossing step that helps prevent adhesion problems before they start.
- For painted, stained, oak, laminate, MDF, and previously finished cabinets
- Use around handles, edges, doors, drawer fronts, and box faces
- Great first product whether you are spraying or brushing and rolling
Building the full project?
Here’s the order I’d follow:
- Cabinet Prep to clean and degloss.
- Cabinet Mud or the Oak Cabinet Grain Filler Kit if you have oak.
- Cabinet Pro Finish Kit when you are ready for the paint-stage setup.
FAQs about cleaning cabinets before painting
Do I really need to clean cabinets before sanding?
Yes. I like cleaning before sanding because grease, oils, and kitchen grime can get smeared or pushed around during sanding. Clean and degloss first, then sand, then remove the dust.
Does Cabinet Prep replace sanding?
No. Cabinet Prep cleans and deglosses. Sanding handles texture, roughness, and surface refinement. For best results, use both steps.
Do I need to rinse Cabinet Prep?
No. Cabinet Prep is a spray-on, wipe-off product. Let the surface dry fully before moving on to sanding, Cabinet Mud, primer, or paint.
Can I just use dish soap and water?
Dish soap can clean surface dirt, but it does not properly degloss cabinet surfaces. If you are preparing cabinets for paint, I would rather use Cabinet Prep because it is made for cabinet painting adhesion prep.
Is TSP better than Cabinet Prep?
TSP can be a strong cleaner, but it is harsher, usually requires careful rinsing, and can create residue problems if not handled correctly. Cabinet Prep is simpler for most DIY cabinet projects because it degreases, deglosses, and does not require rinsing.
Do I use Cabinet Prep before Cabinet Mud?
Yes. Clean and degloss first. Then fill oak grain with Cabinet Mud or the Oak Cabinet Grain Filler Kit before primer and paint.
How much Cabinet Prep do I need?
One 16 oz bottle preps most average-size kitchens. Larger kitchens, very greasy cabinets, or repeated cleaning passes may need more.
What should the cabinets feel like after cleaning?
They should feel clean, dry, and dull — not greasy, slick, wet, or tacky. If an area still feels slippery or contaminated, clean it again before moving on.
