How to Clean Citristrip from Brushes (Even After It Dries)
Clean fresh Citristrip off a brush immediately with warm water and dish soap, worked through the bristles with a brush comb – but once it dries, plain soap and water won’t touch it anymore. For dried-on residue, the trick is re-softening it: seal the brush in a bag with a fresh dab of Citristrip overnight, then comb the loosened gel out in the morning. This guide covers both methods, plus solvent options and proper storage.
Selecting the Right Brush (and Why It Matters for Cleanup)
How easy a brush is to clean afterward depends partly on the brush you picked in the first place. Natural bristle brushes absorb Citristrip’s citrus-based gel deeper into the bristle, which means better application but a harder cleanup. Synthetic bristle brushes resist the gel more, cleaning up faster, but can feel less precise when brushing on a thick, even coat.
Many people who strip furniture regularly use cheap disposable “chip” brushes specifically for Citristrip application and don’t bother cleaning them at all – at $1–$2 each, a new one costs less than the solvent it would take to fully clean the old one. Reserve real cleanup effort for a good-quality natural or synthetic brush you actually want to keep. If you’ve already got dried gel on the workpiece too, see this woodworking tips hub for related finishing and stripping guides.
Recommended Brush Comb
A dedicated two-sided brush comb speeds up both methods above – the brass side lifts residue without damaging bristles, and the stainless pins reshape the brush before it dries.

Wooster Painters Brush Comb – $13.20
The two-sided comb this guide’s Method 2 relies on – non-rusting brass bristles for residue, stainless pins for reshaping before storage.
- Best for: combing softened, re-wetted Citristrip residue out of natural or synthetic bristles
- Why we picked it: brass bristles won’t rust from repeated water exposure like a cheap wire brush can
- Main drawback: only helps once residue is softened – it won’t comb out bristles that are still hard-dry

Pre-Cleaning: Protective Gear and Ventilation
Citristrip is citrus-based and lower-odor than traditional methylene-chloride paint strippers, but it’s still a working chemical stripper – see how long to leave it on a project before you even get to brush cleanup. Wear nitrile or rubber gloves before handling a gel-coated brush, and work in a ventilated area – an open garage or a room with the windows open. A respirator isn’t required for occasional use given Citristrip’s lower toxicity, but wear one if you have respiratory sensitivities or are cleaning several brushes at once.
Effective Brush Cleaning Methods
Method 1: Fresh Citristrip – Soap and Warm Water
If the brush is still wet with Citristrip, act immediately. Scrape off excess gel against the rim of the container with a putty knife, then work warm water and a few drops of dish soap through the bristles with your fingers, working from the ferrule out to the tips. Rinse, repeat, and rinse again until the water runs clear with no orange tint.
Method 2: Dried Citristrip – the Overnight Bag Trick
Once Citristrip dries in the bristles, soap and water alone stops working – the dried gel needs to be re-softened before it will comb out. Work a small, fresh amount of Citristrip into the dried bristles, seal the brush inside a zip-top bag so the gel can’t dry out again, and leave it overnight. In the morning, the dried residue will have softened enough to comb and wash out with the Method 1 steps above. The same re-softening logic is why neutralizing Citristrip on the actual workpiece has its own separate timing rules once the gel is scraped off.
Method 3: Solvents for Stubborn Residue
Mineral spirits or denatured alcohol will cut through leftover residue that soap and water leaves behind. Pour a small amount into a container, dip and gently work the bristles in it, then follow with the soap-and-water rinse from Method 1. Check your solvent’s label for ventilation and disposal requirements – never pour used solvent down a household drain.

Post-Cleaning Maintenance
Proper Storage
- Let the brush air dry completely in a well-ventilated spot before storing – several hours to overnight.
- Reshape the bristles with your fingers once dry to restore their original form.
- Store in a brush holder or case, standing upright so bristles don’t bend or crush.
- Keep the storage area cool, dry, and out of direct sunlight or high humidity, both of which degrade bristles over time.
Inspecting Brush Condition
- Check bristles for fraying, splitting, or clumping – replace the brush if you see significant damage.
- Check the handle and ferrule for cracks or looseness, which affect control during painting.
- Look for any hardened residue that was missed – re-run Method 1 or 2 above before the next use.
- Confirm bristles are still securely set in the ferrule; shedding bristles mean it’s time to retire the brush.
Frequently Asked Questions
How do you remove Citristrip from paint brushes?
Clean the brush immediately while the gel is still wet using warm water, dish soap, and a brush comb, working from the ferrule outward. Rinse until the water runs clear, then reshape and air dry before storing.
How do you clean a brush after the Citristrip has already dried?
Soap and water won’t soften dried Citristrip on its own. Work a small amount of fresh Citristrip back into the dried bristles, seal the brush in a zip-top bag overnight, then comb and wash out the re-softened residue the next day.
Can you clean Citristrip with water and vinegar?
Water alone rinses fresh, still-wet Citristrip off a brush reasonably well; vinegar isn’t necessary and won’t do more than soap and water already does. For dried residue, re-softening with fresh Citristrip (Method 2 above) or a solvent works better than either water or vinegar.
What removes stubborn paint-stripper residue that soap and water won’t?
Mineral spirits or denatured alcohol will cut through residue that soap and water leaves behind. Dip and work the bristles in a small amount of solvent, then finish with a soap-and-water rinse to remove the solvent itself before storing.
Conclusion
Cleaning Citristrip from brushes comes down to timing: soap and water works fine while the gel is still wet, but once it dries, you need to re-soften it with fresh gel or cut it with a solvent before a comb can pull it free. Clean immediately when you can, keep a brush comb on hand for when you can’t, and proper storage afterward will get years more use out of a good brush instead of a one-project chip brush.
