Can WD-40 be used on a sharpening stone?
You can use WD-40 on sharpening stones, especially for cleaning or to free up clogged pores, but it's not the ideal lubricant for sharpening; use it sparingly for cleaning, then switch to water or true honing/mineral oil for better sharpening, as WD-40 is thin and can leave residue, though some users find it works fine on coarser stones or diamond plates, according to this YouTube video and Sawmill Creek community https://www.youtube.com/watch?v=tdS3N8Uo8TU,. For best results, use water or proper honing/mineral oil, and deep clean with kerosene or paint thinner if you used WD-40 extensively.Can WD-40 be used on a sharpening stone?
Your stone will require lubrication to function well. In the sharpening phase, we do not recommend any current WD-40® Brand Products although some may be used later for storage & protection.What can I use to lubricate a sharpening stone?
Motor oil, 3-in-1, WD-30, Balistol, etc. Will all work fine on a stone. They don't damage it, they may feel different (because viscosity changes), but it will be fine. Just don't use vegetable or seed oils, they go rancid in the stone ruining it.What is a good substitute for sharpening stone oil?
You can substitute honing oil with mineral oil (baby oil), light machine/sewing machine oil, or even certain vegetable oils (corn, canola), but avoid drying oils like linseed or motor/gear oils; the best bet is usually a light, non-drying oil like mineral oil or a blend for proper viscosity to carry away metal particles (swarf) without clogging the stone. For waterstones, a drop of dish soap in water works well.What oil should you use on a sharpening stone?
The best oil for sharpening stones is light, non-detergent mineral oil, often sold as sewing machine oil, honing oil, or even cutting board oil (which is food-safe mineral oil), providing lubrication without clogging pores like cooking or motor oils would. While water can work on some stones, oil offers a smoother feel and keeps the stone ready for use, but never use automotive/cooking oils as additives can damage the stone or contaminate blades.Don't Ruin Your Whetstones - Essential Sharpening Stone Care Tips

What viscosity is baby oil?
Baby oil, primarily mineral oil, has a low viscosity, meaning it's thin and flows easily, making it very slippery but also posing an aspiration risk if swallowed, unlike thicker, high-viscosity motor oils; its typical viscosity is around 15-17 centipoise (cP) at room temperature, classifying it as a light, fluid oil good for skin but risky for lungs.Can I use motor oil on a sharpening stone?
In the case of knife sharpening, motor oil is too thick or heavy and can over-lubricate or clog a sharpening stone, whereas WD-40 is too light an oil and will not carry the metal filings plus stone dust (collectively known as swarf) away from the stone, and clog it.Do you wet a sharpening stone before use?
Yes, most traditional whetstones (water stones) need to be wetted, either by soaking them until bubbles stop (for soaking stones) or by splashing water on them (splash-and-go) to create a lubricant slurry, wash away metal particles, and prevent clogging, while oil stones use oil, and some modern diamond plates can be used wet or dry but benefit from water/lubricant. The key is to check your specific stone's instructions, as requirements vary, but water or oil is almost always recommended for optimal performance and stone longevity.Which sharpening stones should be lubricated with sharpening oil?
You should lubricate oil stones, specifically those made from aluminum oxide (like India stones) and silicon carbide, as well as natural Arkansas stones, with honing oil to prevent clogging and carry away metal particles, though some Arkansas stones can use water too. These traditional stones need oil to keep the abrasive surface effective, unlike water stones that use water, or diamond plates that can use water or special spray.What should you not use WD-40 on?
You should not use WD-40 on food-contact surfaces, electronics, car brakes, locks, or anything with sensitive rubber/plastic parts, as it can degrade them or attract dirt, and it's a water displacer, not a long-term lubricant for high-friction areas like chains or bearings. Instead of lubricating, WD-40 cleans and displaces water, so using it where proper grease or oil is needed (like on bike chains or door hinges) can lead to gunk buildup and premature failure.How to smooth out a sharpening stone?
To flatten a whetstone, use a dedicated flattening stone, a diamond plate, or coarse wet/dry sandpaper (like 100-220 grit) attached to a perfectly flat surface (like glass) with water as lubricant, rubbing the dished stone back and forth until pencil marks or dark spots disappear, indicating an even, flat surface for sharpening.How to remove WD-40 from stone?
An oil-based stain will darken the stone and normally must be chemically dissolved so the source of the stain can be flushed or rinsed away. Clean gently with a soft, liquid cleanser with bleach OR household detergent OR ammonia OR mineral spirits OR acetone.What is a substitute for sharpening stone oil?
You can substitute honing oil with mineral oil (baby oil), light machine/sewing machine oil, or even certain vegetable oils (corn, canola), but avoid drying oils like linseed or motor/gear oils; the best bet is usually a light, non-drying oil like mineral oil or a blend for proper viscosity to carry away metal particles (swarf) without clogging the stone.

Can you use Wd40? The viscosity (thickness of the oil) of Wd-40 is a bit thin, which doesn't make it a very good substitute for honing. There is not enough thickness in the oil to do the job of removing the metal shavings and the swarf (particles of the stone).How to unclog a sharpening stone?
Gently Scour the Surface: Next, use a piece of fine steel wool to scour the surface in a gentle manner. This process will take out any grime on your sharpening tool.

Gordon Ramsay primarily uses a honing steel (or rod) for daily maintenance to realign the blade's edge, but for actual sharpening (removing metal), he relies on whetstones (sharpening stones) and sometimes professional sharpening services, though he's shown using specialized tools like the Tumbler Rolling Sharpener for demonstrations on his own knives to achieve extreme sharpness.Is it bad to leave whetstones in water?
Leaving a whetstone in water can be bad because it depends on the stone type; soaking stones (like many ceramic/vitrified ones) are fine to keep wet (add bleach for mold), but non-soaking stones (like some resinoid or magnesia-bonded types) can get mushy, soft, or crack if left submerged long-term, so they should be dried after use, with a splash of water enough for sharpening. Always check manufacturer instructions for your specific stone, but generally, if you don't use it often, store it dry; if you use it frequently, you might keep soaking stones wet.
