Cleaning a Rubik's Cube requires disassembling it, wiping down all pieces with a microfiber cloth or soft brush, optionally using mild soapy water for stubborn dirt, drying everything completely, and reassembling before applying fresh lube. Regular deep cleaning prevents dust buildup from slowing your turns and keeps your cube performing at a competition level.
This guide is for anyone who wants their cube to turn smoothly, whether you're a casual solver working through shape mods and model kits or a competitive speedcuber preparing for events. You'll learn the exact process we use at SpeedCubeShop for maintaining thousands of cubes, from basic 3x3s to complex puzzles.
Here's what we'll cover:
When and why you need to clean your cube
Step-by-step disassembly without breaking pieces
Proper cleaning techniques for different cube types
Drying and reassembly best practices

Common mistakes that damage your cube
Why Regular Cube Cleaning Matters
Dust, skin oils, and old lube create friction inside your cube. This friction slows your turning speed and makes algorithms feel sluggish, which directly impacts your solve times.
If you solve daily or compete, clean your cube weekly. Casual cubers who solve a few times a week should clean every two weeks. You'll notice the difference immediately: smoother corner cuts, faster rotations, and more consistent performance across all faces.
SpeedCubeShop processes thousands of cubes through our Cosmic service, and we've seen how proper cleaning extends cube lifespan by years. The 4.9-star rating from over 5,000 reviews includes feedback on our maintenance guides, which help cubers keep their puzzles in competition shape long after purchase.
Step 1: Gather Your Cleaning Supplies
You need a microfiber cloth, a soft-bristled brush (an old toothbrush works), a small container for pieces, and paper towels. For stubborn grime, grab mild dish soap and a bowl of lukewarm water.
Keep a flat workspace with good lighting. You'll be handling small pieces like centerpieces, edges, and corners, so a clean surface helps prevent losing parts. If you're cleaning a magnetic cube, have a small container ready to keep any loose magnets organized.
At SpeedCubeShop, we stock specialized cube cleaning tools in our accessories section, but household items work perfectly for most cleaning sessions. Save your money for quality lube instead.
Step 2: Disassemble Your Cube Safely
Turn any face 45 degrees, then use your thumb to pop out an edge piece by pushing up from underneath. Once the first edge is out, remove the adjacent corner pieces, then continue removing pieces from that layer.
Never force pieces. If an edge won't pop out, rotate the face slightly and try again. Forcing pieces, cracking plastic, especially on budget cubes or older models.
Lay out your pieces in groups: center pieces in one pile, edges in another, corners in a third. This organization makes reassembly faster and helps you spot any damaged parts that need replacement.
Step 3: Remove Old Lubricant and Debris
Wipe each piece with your microfiber cloth, paying attention to contact points where plastic rubs against plastic. Old lube turns black and sticky, so you'll see it come off on the cloth.
Use your soft brush to clean grooves and recessed areas where dust collects. The insides of corner pieces trap the most debris, so spend extra time there. For centerpieces, clean both the visible cap and the internal mechanism.
If you're doing a deep cleaning on a cube that hasn't been maintained in months, dip your cloth in soapy water and wring it nearly dry. Wipe all surfaces, then immediately dry each piece with a paper towel. Water won't damage plastic, but moisture left inside creates problems during reassembly.
Step 4: Clean the Core and Hardware
The core is the central mechanism holding your cube together. Wipe down all visible screws, springs, and the core itself with your damp cloth. Remove any dust or old lube buildup.
Check your spring tension while the cube is apart. Uneven springs cause lockups and poor corner cutting. If you're unsure about proper tension, our guides' shop at SpeedCubeShop includes detailed posts with search results for specific cube models.
Dry the core completely before reassembly. Any moisture here will mix with your new lube, reducing its effectiveness.
Step 5: Dry Everything Thoroughly
Lay all pieces on paper towels and let them air dry for 15-20 minutes. Even if you only used a damp cloth, moisture can hide in small crevices.
Don't rush this step. Reassembling a wet cube dilutes your lube and can cause pieces to stick. If you're in a hurry, use a hairdryer on a cool setting, but air drying is safer for plastic longevity.
While pieces dry, wipe down your workspace. You'll be applying lube next, and you don't want dust to contaminate the fresh lubricant.
Step 6: Reassemble Your Cube
Start by inserting the center pieces back onto the core. Then add edge pieces one at a time, followed by corners. The last corner requires sliding it in at an angle while slightly turning the adjacent face.
Test the cube after reassembly by turning each face. It should feel dry and slightly scratchy without lube, but all pieces should move freely. If anything catches or gets locked up, disassemble that section and check for debris or misaligned parts.
Your cube is now clean and ready for fresh lubrication. This is when you'll see the biggest performance improvement.
Step 7: Apply Fresh Lubricant
Use cube-specific lube, not household oils. Apply 1-2 drops of fast lube to the pieces, then 1-2 drops of slow lube to the core and springs. Break in the lube by solving the cube 20-30 times.
Different cubes need different lube weights. SpeedCubeShop carries specialized lubricants formulated for speedcubes, and our product descriptions tell you exactly which lube works best for your specific model. We've tested these combinations on thousands of cubes through our Cosmic service.
Too much lube is worse than too little. Start conservative, solve for a few hours, then add more if needed. You can always add lube, but removing excess requires another full cleaning.
What Not to Use When Cleaning
Never use WD-40, cooking oil, petroleum jelly, or other household lubricants. These products break down plastic over time and attract dust, making your cube worse than before cleaning.
Avoid harsh chemicals like bleach, acetone, or alcohol-based cleaners. They can dissolve the adhesive holding stickers or magnets in place. Stick to water and mild dish soap for wet cleaning.
Don't submerge your entire cube in water. While individual pieces can handle brief water exposure, soaking can cause spring rust and trap moisture in hollow pieces.
Cleaning Different Cube Types
Magnetic Cubes
Handle magnetic cubes gently during disassembly. Magnets are glued into slots, and rough handling can pop them loose. If a magnet comes out, note its polarity before reglueing.
Clean around magnets carefully with a dry cloth. Water can weaken the adhesive holding magnets in place. If you must use soapy water, keep it away from magnet slots.
Stickerless Cubes
Stickerless cubes are the easiest to clean since you don't need to worry about water damage to stickers. You can use slightly more moisture when wiping pieces.
The plastic on stickerless cubes can show scratches more easily than stickered versions, so use a soft cloth and gentle pressure. Abrasive scrubbing dulls the finish.
Larger Puzzles (4x4, 5x5, and Beyond)
Bigger cubes have more pieces and more complex internal mechanisms. Budget extra time for disassembly and cleaning. Take photos during disassembly if you're new to larger puzzles.
Focus your cleaning on the outermost layers and center mechanisms where dust accumulates most. Inner layers usually stay cleaner and need less attention.
How to Clean Without Full Disassembly
If you're short on time, you can do a quick surface clean. Wipe all visible surfaces with a damp cloth, then use compressed air to blow dust out of gaps between pieces.
This method works for maintenance between deep cleanings but won't remove old lube buildup or dust from internal contact points. Plan to do a full disassembly cleaning every month, even if you do weekly surface cleans.
SpeedCubeShop recommends full cleaning for competitive cubers before major events. The performance difference is measurable, and you don't want sluggish hardware costing you seconds during a solve.
Maintaining Your Cube Between Cleanings
Store your cube in a case or bag when not in use. This keeps dust off and prevents accidental drops that can crack pieces or knock them out of alignment.
Wash your hands before long solving sessions. Skin oils are the main cause of lube breakdown, and clean hands extend the time between necessary cleanings.
Do a quick wipe-down after every session if you solve daily. A 30-second wipe with a microfiber cloth removes surface dust before it works its way inside. This habit cuts your deep cleaning frequency in half.
When to Replace Instead of Clean
If pieces are cracked, stripped, or deformed, cleaning won't fix the problem. SpeedCubeShop stocks replacement parts for many popular models, but sometimes buying a new cube makes more sense than repairing an old one.
Modern cubes from 2026 use better plastics and engineering than models from even five years ago. If your cube is old enough that cleaning doesn't restore smooth performance, consider upgrading to a current model.
We offer a 90-day return policy on all cubes, so you can try a new model risk-free. Our same-day fulfillment means orders placed before 1 PM Pacific ship the same business day, getting your new cube to you fast.
Frequently Asked Questions
How do I clean my Rubik's Cube?
Disassemble your cube by popping out edge pieces, then wipe all parts with a microfiber cloth to remove dust and old lube. For stubborn dirt, use a damp cloth with mild soap, dry everything completely, reassemble, and apply fresh cube lube. This process takes 20-30 minutes and should be done weekly for daily solvers or every two weeks for casual use.
Is WD-40 good for Rubik's cubes?
No, never use WD-40 on a Rubik's Cube. WD-40 is a solvent-based product that breaks down plastic over time, attracts dust, and creates a sticky residue that ruins cube performance. Use cube-specific silicone lubricants designed for speedcubes instead, which SpeedCubeShop carries in various weights for different turning preferences.
What happens if you put a Rubik's Cube in water?
Submerging an assembled cube in water can cause spring rust, trapped moisture in hollow pieces, and weakened adhesive on stickers or magnets. Individual disassembled pieces can handle brief water exposure for cleaning, but you must dry them completely before reassembly. A damp cloth is safer than full immersion in water for most cleaning needs.
What to lubricate Rubik's Cube with?
Use cube-specific silicone lubricants in different weights: fast lube (thin) for pieces and slow lube (thick) for the core and springs. SpeedCubeShop offers lubricants formulated specifically for speedcubes, with product descriptions explaining which weight works best for your cube model and turning style. Never use household oils, cooking spray, or petroleum-based products.
