Steps to Strip Paint from Metal Cabinets
Removing old paint and getting metal ready for new paint involves multiple steps. Here is the basic process:
1. Remove Cabinet Doors and Drawers
- Detach all cabinet doors, drawers, shelves, and hardware prior to stripping. This allows you to work on each piece individually.
- Number each door and drawer to ensure proper reinstallation in the original locations.
- Set the hardware like knobs and hinges aside in a secure container to avoid losing any pieces.
2. Clean the Cabinets
- Use a degreasing cleaner or soap and water to wash cabinet surfaces and remove any dirt, grease or grime before stripping.
- Dry all cabinet surfaces fully with a clean towel. Let them air dry to ensure there is no residue.
3. Apply the Paint Stripper
- Shake or stir the paint remover thoroughly before using. Follow all label directions.
- Use a chemical-resistant brush to generously apply a thick coat of stripper to a small section of the cabinet.
- Let the stripper sit for 15-30 minutes without allowing it to dry out. Reapply as needed.
- Scrape in the direction of the wood grain using your paint scraper to loosen the softened paint.
- Wipe away all paint stripper residue with rags. Use paint thinner to finish cleaning.
- Repeat the process on small sections until all paint is removed from doors, drawers and cabinet boxes.
4. Finish Stripping with Sanding
- Sand all surfaces lightly with 80-100 grit sandpaper to smooth and prep them after using the chemical stripper.
- Do not press too hard to avoid scratching or gouging the metal. Carefully sand hard-to-reach crevices.
- Finish by sanding all cabinets, doors and drawers with 150-220 grit paper for a final smooth finish.
- Wipe away all sanding dust using a dry cloth.
5. Clean and Prepare for New Paint
- Use a tack cloth to pick up any remaining dust or residue after sanding.
- Clean all surfaces with paint thinner one final time. Allow to fully dry.
- Fill any pits, holes or imperfections with metal filler as needed. Sand smooth when dry.
- Metal cabinets are now ready for priming and painting with suitable metal paint.
Tips for Effectively Removing Paint from Cabinets
Follow these tips to help tackle the paint removal process efficiently:
- Work in manageable sections for the stripper, one cabinet side or door at a time. Don’t let stripper dry on surfaces.
- Apply a very thick coat of remover to save time and avoid extra scrubbing.
- Keep cabinets wet with stripper by reapplying frequently during the dwell time.
- Use coarse sandpaper on a sanding block for best grip and control when sanding.
- Always wear gloves and work in a well-ventilated area due to harsh stripper fumes.
- Rinse rags often since paint residue can hinder remover effectiveness. Replace rags as needed.
- Avoid metal scrapers which can scratch and damage cabinet surfaces during paint removal.
- If original cabinet finish will be restored, use extra care not to over-sand surfaces when prepping.
- Properly store flammable paint thinning solvents. Allow all surfaces to dry fully before painting.
- Work slowly and thoroughly to avoid any drips or splatters of stripper on floors and surfaces.
Alternative Methods for Paint Removal
While using a chemical paint stripper is typically the most effective approach for removing paint from metal cabinets, some alternative methods include:
Heat Gun
- Use a heat gun to soften and loosen thick, built-up paint layers from metal cabinet surfaces.
- Move the heat gun constantly to avoid damaging the metal. Scrape away paint as it softens.
- Heat guns work best for small areas and details rather than entire cabinets. Take precautions against burns.
Orbital Sander
- An orbital sander with coarse sandpaper can be used to sand away paint from metal cabinets.
- This generates a lot of dust and may take longer than chemical strippers on thick paint.
- Use lighter pressure and finest grit paper as you get closer to the bare metal to avoid scratching.
Paint Dissolving Liquid
- Some mild, eco-friendly paint dissolving liquids can soften and remove paint layers without harsh methylene chloride.
- Apply the liquid and let it work for several hours or overnight before scraping.
- Test dissolution liquids first, as results vary based on paint type and thickness. Several applications may be needed.
Safely Disposing of Used Paint Remover
Proper disposal of used paint stripper and paint residue is important:
- Allow rags and brushes used for remover to fully air dry before disposal to avoid combustion.
- Check local regulations, as some areas require certain liquids to be disposed of as hazardous waste.
- For small amounts of dried residue, household trash disposal is often permitted. Double bag it first.
- Safely transport any liquid waste to a waste collection site in sealed, labeled containers once fully solidified.
- Never pour paint stripper liquids or waste down drains, sinks or toilets or dispose of improperly outdoors.
- Recycle or donate any still-usable paint thinner or solvents to avoid the need for disposal whenever possible.

What Type of Paint Stripper is Best for Removing Paint from Metal Cabinets?
When selecting a paint stripper to remove layers of old paint from metal cabinets, choosing the right formula is key for safety and effectiveness. Here are some important considerations when picking the best type of paint stripper for metal cabinets:
Gel or Liquid Remover
Thick gels and pastes are ideal for clinging to vertical cabinet surfaces and penetrating through paint layers without running or dripping. Liquid strippers may be too thin and run off before fully dissolving thick paint.
Cling Control Additives
Look for paint strippers formulated specifically for metal with ingredients to help the product cling tightly as it works to soften paint layers. Common cling control additives include urea formaldehyde and evaporated milk solids.
Avoid Harsh Methylene Chloride
Many pros recommend avoiding methylene chloride-based strippers for indoor cabinet refinishing due to the very harsh vapors. Opt for safer methylene chloride-free removers whenever possible.
Strong Enough for Multiple Layers
Cabinets often have several coats of paint built up over time. Choose a remover powerful enough to cut through and dissolve several layers for less hassle and scrubbing.
Easy Water Cleanup
Seeking strippers that can be cleaned up with just water can help simplify the process. Avoid options that require paint thinner, mineral spirits or other solvents to remove residue.
Fast-Acting Formula
Look for paint strippers specially formulated to work quickly on metal surfaces. The shorter the required dwell time before scraping, the faster the project can be completed.
Balanced Safety
Select a remover that is safe to use on metal cabinets but still effective. Avoid extreme caustic formulas reserved for industrial uses. Read all warnings carefully.
Quality Brand Reputation
Trusted brands known for specializing in paint strippers like Strypeeze, Citristrip, or Savogran can offer reliably effective results for DIY cabinet refinishing.
By selecting the best type of stripper for your specific cabinets, you can safely and easily remove all old paint for a smooth, clean surface primed for new paint adhesion.

Common Problems When Removing Paint from Cabinets
Stripping paint from cabinets can sometimes hit frustrating snags or issues. Being aware of common problems ahead of time helps you avoid them:
Remover Not Working
If paint is not softening and bubbling, the remover may be old or the formula too weak. Try a fresh can of a quality thick gel stripper. Reapply frequently.
Dry Spots Develop
Paint stripper drying out before dwell time is up prevents proper paint removal. Constantly rebrush with remover to keep wet. Use thinner coats.
Metal Damage
Scraping too aggressively can scratch metal. Take care when scraping to only remove paint, not gouge the cabinet surface.
Harmful Fumes
Some harsh removers have dangerous vapors. Wear a respirator and ensure proper ventilation. Avoid methylene chloride.
Messy Drips
Liquid strippers may drip during application, creating a runny mess. A thicker gel clings better to vertical surfaces.
Residual Odor
Even when thoroughly rinsed, some removers leave lingering odors behind. Opt for low-odor and fume-free formulas whenever possible.
Stripper Residue Remains
If the remover brand isn’t formulated for easy water cleanup, residue may require mineral spirits to remove.
Uneven Results
If paint removal is patchy,varying times were likely allowed for the stripper to work in different spots. Maintain consistency.
Staying aware of common frustrations allows you to take steps to avoid them. Applying remover properly and following all label directions leads to smooth, even stripping.
How to Sand Cabinets After Removing Paint
Sanding is an important step after stripping cabinets to prepare the surface for new paint. Here are tips for effective post-strip sanding:
Supplies Needed
Gather sandpaper in varying grits like 80-grit for initial smoothing, then 120-150 for finer sanding. Also have sanding sponges, tack rags and a sander.
Remove All Paint Residue
Ensure all paint, stripper and residue are fully removed using mineral spirits before sanding to avoid gumming up the paper.
Start With Coarse Paper
Use 80-100 grit paper to smooth and level the surface after paint stripper. Remove any remaining paint spots.
Sand With the Grain
Always sand in the direction of the wood grain on cabinet doors and drawers to avoid scratching.
Get Into Corners
Use detail sanding sponges to smooth hard-to-reach corners and crevices.
Smooth Edges
Carefully sand where stripped and non-stripped paint areas meet to feather the edges for a smooth transition.
Change Sandpaper Frequently
Swap out gummed up sandpaper often to keep sanding effective. Consider using an orbital sander for efficiency.
Finish With Fine Sanding
Do a final pass with 120-220 grit sandpaper for an ultra-smooth foundation for painting. Avoid over-sanding.
Thoroughly Remove Dust
Wipe sanded cabinets with a tack rag to remove all dust before priming or painting. Overlooked dust can ruin paint adhesion.
Proper sanding ensures cabinets are properly prepped and smoothed for success with new paint. Take time for this important step.
How to Avoid Common Paint Stripping Mistakes
Paint stripping cabinets is a multi-step process that requires care to avoid making mistakes. Here are tips for avoiding common errors:
Read All Label Directions
Failing to read stripper directions can lead to inadequate dwell times, chemical burns, or insufficient ventilation. Always follow instructions.
Don’t Allow Remover to Dry
Once applied to cabinets, keep the stripper wet by adding more. If allowed to dry, the paint will not fully soften.
Avoid Metal Scrapers
Scrapers made from materials like metal, putty knives, or razor blades risk scratching and damaging cabinets. Use plastic instead.
Take Care When Sanding
Sanding too roughly after stripping or using overly coarse grit can damage the original wood underneath. Be gentle.
Ensure Thorough Rinse
Left over stripper residue prevents proper paint adhesion later. Verify full removal with mineral spirits after water rinse.
No Direct Sunlight
Heat from direct sun causes remover to dry out too quickly on outdoor cabinets. Work in shade or tent the area.
Proper Brush Type
Avoid nylon brushes, as they deteriorate quickly. Acid brushes made for stripping work best.
Keep Surfaces Wet
When applying remover, keep going over entire area to maintain a wet coat, preventing premature drying.
Don’t Rush Dwell Time
Impatience leads to inadequate paint removal. Wait the full recommended time before scraping for best results.
Taking the time to apply remover properly prevents many common mistakes and headaches down the road.
