Lexol vs Bickmore Bick 4

The two conditioners most people end up choosing between, separated by one published figure and one cosmetic promise. Neither is a waterproofer, and that is the mistake to avoid.

Lexol if the boots have dried out and gone stiff. Bick 4 if the color is the thing you are protecting. That is the whole decision, and everything below is the reasoning behind it.

These two get compared constantly because they occupy the same shelf position - mid-price, widely stocked, general-purpose leather conditioners for footwear. They are not the same product, but the difference is smaller than the internet suggests, and neither one is capable of ruining a pair of boots.

Everything in the Lexol column comes from Lexol’s own product page. The Bickmore column is thinner because Bickmore publishes a catalog rather than a spec sheet, and we are not going to fill the empty cells with numbers from a review site.

The published interval is the single biggest difference

Lexol prints a reapplication interval: every six months for ongoing care. Almost nobody in this category does. It is the reason Lexol tops our conditioner roundup, and it is worth being precise about why a maintenance schedule counts as a feature.

Conditioning is the one boot-care step where doing it on a rhythm beats doing it when you remember. Leather loses oils slowly and invisibly, and by the time it looks dry the fibers have already been flexing without lubrication for months. A published number turns a vague intention into a diary entry, and a diary entry is what actually gets done.

Two honest caveats. Six months is Lexol’s figure for ongoing care in general use, not a promise about a boot that spends a winter in road salt - in that situation monthly is far more realistic. And a published interval is not the same as a proven one; it is a manufacturer committing to a recommendation in writing, which is a documentation win rather than a performance one.

A thin liquid gets into the fiber structure. A cream sits closer to the surface and buffs up. Both are conditioning; they are not doing it in the same place.

Liquid against cream, and what that changes

Lexol is a thin liquid, which means it soaks in rather than sitting on top. On a boot that has genuinely dried out and gone rigid, that penetration is the point - you want the conditioner reaching the fibers that have stopped flexing, not forming a film over them.

Bick 4 is a cream. It goes on with a cloth, absorbs quickly enough that the boots go back on the same day, and buffs to a slight finish. For routine maintenance on a boot that is basically healthy, that is a more pleasant product to use and the result looks better afterwards.

The failure mode of a liquid is over-application: it is easy to put on too much, and surplus conditioner that never absorbs attracts grit and does nothing useful. The failure mode of a cream is under-penetration on badly dried leather. Match the product to the state of the boot rather than to a brand preference.

The darkening question

Bick 4 is sold specifically on not darkening leather, and for a lot of buyers that is the whole reason they are on this page. If you own light tan boots, or anything where the finish is the point, that promise is worth more than a published interval.

Lexol publishes no darkening claim either way. In practice most conditioners darken most leather slightly, and any oil-based product on unfinished or aniline leather can do more than slightly. Whichever you use, the rule is the same and it is not optional: test on a hidden area first - low on the heel counter or under the tongue - and wait for it to dry fully before judging the color.

Neither of these is a waterproofer

This is the mistake that actually costs people boots. A conditioner feeds leather; it does not seal it. Lexol’s own card here lists “no barrier against water” as a con, and Bick 4’s lists “no waterproofing at all”. Conditioning a boot and walking into a wet winter with nothing else on it is not a plan.

The order is clean, dry completely, condition, then proof - the waterproofer goes last because its job is to stop liquids entering the leather, including the conditioner. Products for the last step are in the leather waterproofing roundup.

Neither one is for suede

Both are for smooth, finished leather. A liquid conditioner flattens and stains a napped surface, and a cream mats it. Suede is maintained mechanically - a brass-and-nylon brush and a crepe eraser block - and never conditioned, waxed, oiled or soaped. Full method in how to clean suede boots.

Where the Bickmore pairing earns its place

Bick 1 and Bick 4 are designed to be used together: the cleaner lifts old dressing and salt so that the conditioner can actually absorb, rather than sitting on top of a layer of last year’s product. That is a real workflow advantage over buying two unrelated products, and it is why Bick 1 is on this page at all.

It is also the honest con of the pair: it is a two-product routine and two purchases. Lexol’s counter-argument is that one bottle covers boots, bags and car seats, which for a lot of households is the more useful kind of value.

How to apply either one

The method barely differs between them, and it is short. What matters is doing all five steps rather than the two people usually do.

  1. 01

    Clean the boots, and let them dry

    Conditioner over road grime bonds to the grime. Dry mud brushes off; wet mud smears into the grain. Clean dry, then dry fully before anything else goes on.

  2. 02

    Test on a hidden area

    Low on the heel counter or under the tongue. Let it dry completely before judging the color - a patch that looks dark when wet often is not once it has absorbed. This step is not optional on unfinished or aniline leather.

  3. 03

    Thin coat, worked in with a cloth

    Small amount on a cloth or your fingers, in circles. Cover the flex crease across the vamp and the welt area generously - those are where the leather works hardest and cracks first. More product is not more conditioning.

  4. 04

    Let it absorb

    A few hours somewhere warm - warm, not hot. A thin liquid such as Lexol goes in faster than a cream; a cream such as Bick 4 usually absorbs quickly enough that the boots go back on the same day.

  5. 05

    Buff off whatever did not absorb

    Surplus left on the surface attracts grit and stops a waterproofer taking properly afterwards. The only conditioner that counts is the conditioner that went in.

What the missing documentation means in practice

Lexol publishes an interval, a form, a size range and a composition claim. Bickmore publishes a catalog. That gap is why Lexol scores higher on documented use in our own metric breakdown, and it is worth being honest about what it does and does not tell you.

It does not mean Bick 4 is a worse conditioner. It means that if you want to know how often to reapply it, nobody at Bickmore has written that down, so you are working from the boot rather than the label. That is a workable position - reading the flex crease is a better instrument than a calendar anyway - but it is a real difference between the two products and we score it accordingly rather than treating published information as decoration.

When the answer is neither

If your boots are genuinely rigid - work boots that have been soaked and dried hard, or something that has sat in a garage for a decade - a general conditioner may not be enough, and the product people reach for is mink oil. Understand what that trade is before you make it: mink oil softens leather structure and darkens it permanently. On a boot that needs to hold your ankle, softening the structure is a real downside rather than a bonus. The comparison is in mink oil vs leather conditioner.

And if the boots are wet right now, neither product goes on yet. The fiber spaces are full of water, so an oil-based conditioner cannot get in - you get a greasy surface over untreated leather, and you slow the remaining moisture from leaving. Wait until they are dry through: conditioning boots after they get wet has the timing.

How to choose

Buy Lexol if the boots have dried out and gone stiff, if you want a published schedule to follow, or if one bottle covering the car seats too is genuinely useful. Buy Bick 4 if the color of the leather matters, if you prefer a cream to a liquid, or if you are already using Bick 1 as your cleaner. On a healthy pair of boots conditioned on a sensible rhythm, you will not be able to tell which one you used - and how often that rhythm should be is in how often to condition boots.

Questions

Frequently asked

Is Lexol or Bick 4 better for boots?

Lexol for boots that have dried out and gone stiff - it is a thin liquid that penetrates, and Lexol publishes a six-month reapplication interval. Bick 4 for boots where the color matters, since it is sold specifically on not darkening leather. Both are fine general conditioners for smooth leather.

Does Bick 4 darken leather?

Bickmore sells it specifically on not darkening most leathers, which is its main selling point against the rest of the category. As with any conditioner, test on a hidden area first and let it dry fully before judging - unfinished and aniline leathers react less predictably than finished ones.

How often should you use Lexol on boots?

Lexol publishes every six months for ongoing care. That figure assumes general use rather than a winter of road salt; if the boots are being cleaned repeatedly through a salted season, monthly is more realistic because every clean takes oils out along with the salt.

Can you use Lexol or Bick 4 on suede?

No. Both are for smooth finished leather. A liquid conditioner stains and flattens a napped surface and a cream mats it. Suede is maintained mechanically with a brush and a crepe eraser block, and never conditioned.

Do leather conditioners waterproof boots?

No, and this is the most expensive misunderstanding in boot care. A conditioner feeds the leather so the fibers keep flexing; it does not create a barrier. Condition first, then apply a separate waterproofer, in that order.
