To clean a multi-tool: remove loose dirt with a soft brush, use the cleaning method its manufacturer allows, dry the joints completely, then apply a little suitable lubricant to the pivots. Wipe away the excess and check that each implement opens, closes and locks normally before putting it away.
A gritty hinge, sticky blade and rusty plier head need different treatment. Start with the problem you can see; flooding everything with oil can leave the original dirt sitting inside the tool.
This guide covers routine care for folding, plier-based multi-tools. A broken lock, bent implement or damaged pivot needs repair, rather than a more aggressive cleaning session.
What should you use to clean a multi-tool?
Set out a soft toothbrush, lint-free cloth, cotton swabs, a shallow dish and the lubricant specified for your tool. Have mild soap available if the manufacturer’s instructions allow it. Work on a clear, well-lit surface where an open blade cannot disappear under a towel.
| Problem | Start here | Avoid |
|---|---|---|
| Pocket lint or dry dust | Soft brush and careful wiping | Forcing grit through the hinge |
| Food residue or sticky handles | Maker-approved mild washing | Strong solvents on unknown finishes |
| Saltwater exposure | Freshwater rinse, thorough drying and appropriate protection | Putting it straight back in its sheath |
| Light surface staining | Gentle cleaning; follow the maker’s rust guidance | Starting with a powered abrasive |
| Loose parts or a lock that fails | Stop using it and arrange service | Treating a mechanical fault as dirt |
Routine-care decisions based on the manufacturer instructions linked below. Check the instructions for your exact model and finish.
Keep cleaning supplies separate from your food kit. If the blade prepares food, check the lubricant’s intended use and label as well as the tool maker’s advice. An oil described as suitable for incidental food contact is not an ingredient.
Check your brand’s instructions before washing
There is no single soaking recipe for every multi-tool. Handle materials, coatings, accessories and manufacturer guidance differ. These are the useful differences in the current care instructions, rather than permission to soak any tool carrying the same logo.
| Manufacturer | What its guidance says | Practical implication |
|---|---|---|
| Leatherman | Mild detergent and water for sticky substances; thorough drying and lubrication afterward | Clean the contamination first, then protect the joints |
| Gerber | Use fresh water and a soft brush; dry completely and apply light oil | Give the hidden spaces the same attention as the visible surfaces |
| SOG | Mild soap solution; avoid harsh detergents and chlorine; best not to immerse the tool | Do not transfer a soaking routine from another brand |
| Victorinox | Regular cleaning and oiling; no dishwasher cleaning | Use the Swiss Tool care instructions for plier-based models |

How to clean a multi-tool, step by step
1. Inspect it before opening everything
Check for cracks, loose hardware, bent tips and obvious damage. Move implements individually, keeping fingers clear of their closing paths. You do not need a fan of exposed blades to clean one pivot.
If a blade is stuck, stop before the force needed becomes difficult to control. A tool that suddenly releases can be more dangerous than one that stays shut. Ask the manufacturer about service if ordinary cleaning does not restore normal movement.
2. Brush out dry debris
Remove pocket lint, dry soil and loose grit with the soft brush. A cotton swab can reach shallow recesses, but check that it does not leave fibers behind. Wipe the plier jaws and the channels where the implements fold.
Do this before adding oil. Lubricating a visibly dirty hinge makes it harder to tell whether the original obstruction has actually gone.
3. Wash only as much as the instructions require
For sticky residue, follow the brand guidance above and your model’s care sheet. Use gentle cleaning and a soft brush; keep your hand behind the cutting edge. Rinse away cleaning residue where the instructions permit rinsing.
Do not invent a long soak because the first pass was slow. Electronics, removable accessories and unfamiliar handle materials deserve a separate check before they get wet. Remove detachable accessories only as directed, rather than dismantling the pivot assembly.
Wipe the outside, then carefully reposition the implements so you can reach the handle channels and hinge areas. Leave the tool in a secure place to finish drying, away from children and pets.
Do not put a damp tool into a pouch to “dry later.” The blade can look dry while moisture remains inside a handle. Avoid a flame, oven or improvised high-heat drying method.
5. Lubricate the moving joints sparingly
Use the lubricant recommended for your model, following its label. Apply a small amount at the moving joints, gently work each implement through its travel and wipe off the excess. A dripping handle is not the goal.
Pay attention to where the oil goes. A cutting edge, a pivot and a screwdriver tip do different jobs; coating everything heavily makes the tool slippery and leaves residue on whatever you work on next.
6. Check operation and store it dry
Open and close each implement individually. Check the manufacturer’s locking procedure with your hands outside the blade’s closing path. Confirm that the pliers operate normally and that all implements fold fully away.
If movement remains gritty or a lock behaves inconsistently, stop using the affected tool. Dry the sheath separately, and store the multi-tool where it will stay dry. Make the final check before your trip, rather than beside a repair that already needs doing.
How should you clean a multi-tool after saltwater?
Saltwater calls for prompt care. Leatherman and Gerber both advise freshwater cleaning after exposure, followed by drying and suitable protection. Wiping the outside alone leaves the handle channels and joints untreated.
After rinsing as directed, follow the drying and lubrication steps above. Check removable bits, the pocket clip and the sheath too. A wet pouch should not become the place where your freshly cleaned tool spends the night.
Stainless does not mean maintenance-free. A stainless blade does not make the rest of the tool immune to corrosion. Different parts, trapped moisture and the conditions in which you store the tool all matter.
For frequent marine use, follow the maker’s guidance on protective products and inspect the tool between outings. A more corrosion-resistant blade is useful, but it does not replace caring for the joints and other implements.
Can you remove rust without damaging the finish?
Start gently. Clean off dirt so you can see whether you are dealing with a surface mark, residue or deeper damage. Follow the maker’s recommended treatment for the exact finish; advice for bare stainless steel may be unsuitable for a coated handle.
Leatherman’s care page includes non-metallic abrasive cleaning, while other manufacturers describe different products and methods. That is a reason to check your own instructions, rather than treat steel wool or a rotary tool as a universal fix.
Deep pitting, a weakened cutting edge or corrosion that interferes with a lock needs assessment. Do not polish away evidence of damage and assume the part is sound. Take clear photos and contact the manufacturer if you are uncertain.
Can you use WD-40 on a multi-tool?
Some manufacturer instructions mention a water-displacing product as part of cleaning or corrosion protection. SOG’s care page is one example. That does not make every product sold under the WD-40 name interchangeable, or suitable for every blade’s next use.
Distinguish removing moisture from choosing the lubricant that stays in the pivot. Read the exact product label and your maker’s instructions. If the tool cuts food, choose and use the relevant maintenance product accordingly, then clean the food-contact surfaces before use.
Should you take a multi-tool apart to clean it?
Routine cleaning should not require taking the pivot assembly apart. Reassembly can affect spacing, spring tension and locking behavior. A video showing another model being dismantled is not an instruction sheet for yours.
Some tools have manufacturer-approved replaceable cutters or accessories. Replacing those parts according to their instructions is different from stripping the whole tool. For persistent stiffness or a damaged mechanism, check the service route before turning screws.
How often does a multi-tool need cleaning?
Use its condition and exposure as the trigger. Remove food residue after use, deal with saltwater promptly and clean out grit when it appears. A pocket tool carried in a dry office will not need the same routine as one used around sand, mud or spray.
Before a trip, check movement, locks, bits and cutting edges while you still have time to fix a problem. Our camping checklist helps with the rest of that preparation.
If cleaning has made you reconsider a tool used for repairs, compare the driver, plier and carry choices in our multi-tools for mechanics guide. The Leatherman Rebar review also explains a simpler fixed-driver layout, with fewer loose accessories to keep track of.
