Quick Answer: Log it as Found if you can confirm you have the right container, and file a Needs Maintenance at the same time. Do not skip the Found log out of politeness — the maintenance flag is what actually gets the container fixed. If you can improve it in the field without replacing the owner’s container, do so and describe exactly what you did in the log. A pen mark on a soaked log page is worthless, so photograph the container instead as your record.

You reach into the hollow, feel the container, pull it out, and it sloshes.

Inside is a grey papier-mache brick that used to be a logbook. Here is what actually to do, in what order, and how not to make it worse.

Why do containers flood in the first place?

Almost never because water was poured in. Nearly always because of a slow mechanism that took weeks.

Temperature cycling pulls water in. A sealed container warms in the afternoon and the air inside expands and escapes past the seal. At night it cools, the air contracts, and the container draws in whatever is against the seal — which in autumn is condensation or standing water. Over enough cycles, a technically watertight container fills. This is why caches that were bone dry all summer are wet by October, and it is the single most common cause.

Seals fail from UV before they fail from wear. Rubber gaskets on cheap containers go hard and chalky after a season or two of sunlight, even in shade — the container itself embrittles too. A gasket that no longer compresses is a gasket that no longer seals.

Threads get contaminated. A single pine needle, a grain of grit or a leaf fragment across a screw thread holds the lid a fraction of a turn open. That gap is more than enough. This is the failure most often caused by the previous finder rather than the weather.

Placement collects water. A container sitting upright in a hollow, under a drip line from a branch, or in the base of a stump is in a place that concentrates water. The same container ten centimetres higher and tipped lid-down stays dry for years.

Condensation alone can soak a log. A container does not need to leak to ruin a logbook. Damp air sealed inside on a humid day condenses on the cold plastic every night, and a paper log in a small container absorbs it all. This is why a completely intact, properly sealed container can still hold a soaked log — and why blaming the last finder is often wrong.

What do you actually log?

Log the find, log the problem, and separate the two clearly.

Log Found if you found it. There is a persistent instinct to skip the log or to log a DNF out of some sense that a wet cache does not count. It does. You located the container, which is the task. Owners need accurate find data to understand whether the cache is findable, and a missing log muddies that.

File Needs Maintenance as a separate action. This is the part people leave out, and it is the part that actually does something. The attribute flags the listing for the owner and, if it goes unaddressed, for reviewers. A polite mention buried in a Found log text is far less likely to be acted on than the formal flag. Both together is the correct combination: found it, and it needs attention.

Be specific in the text. Container wet is nearly useless. Lid seal is cracked on one side, logbook is pulp, container had about 2cm of standing water, I emptied it and left it lid-down under the same rock tells the owner exactly what to bring and whether they need to make a trip today or next month.

Photograph it. A picture of the wet interior does more than a paragraph, and it protects you if there is later any question about the state you found it in. Do not photograph the hiding place itself in a way that spoils it for others — a close crop of the container against your hand is enough.

Say if you could not sign. Log too wet to sign, photo attached is a completely standard and accepted log. Almost no owner will delete a find over an unsignable log, and the photo is your evidence.

Do not sign a soaked log. Pen ink on wet paper tears it and spreads into an unreadable smear, and you will have destroyed what was left of the earlier signatures. If it is merely damp, a pencil works far better than a pen.

What Nobody Tells You About Field Repairs

There is a line between a helpful improvement and quietly taking over someone else’s cache, and it is worth knowing where it sits.

Things almost every owner is glad you did: emptying standing water out; clearing grit off the threads and re-seating the lid properly; replacing a ruined log sheet with a fresh strip of paper in a small bag; putting the container back tipped or lid-down so it drains; adding a zip bag around a damp log.

Things to ask before doing: replacing the container entirely. A different container changes the cache — sometimes the container is the point, sometimes it is a size the owner chose deliberately, and a well-meaning swap can break a puzzle or a theme. A message to the owner takes a minute.

Things not to do: moving the cache to a better spot. Coordinates are the owner’s, the hide is the owner’s, and a container moved even a few metres generates DNFs for everyone after you. Note the drainage problem in your log instead and let the owner decide.

Carry a small repair kit and it stops being a dilemma. A few zip bags, a strip of waterproof paper or ordinary paper cut to size, a pencil, and a spare small container weigh almost nothing. Regular cachers who carry this fix more caches in a season than most owners maintain.

Waterproof paper is the genuine upgrade. Synthetic log sheets shrug off the damp that destroys ordinary paper, and one sheet costs very little. If you replace a log, replacing it with waterproof paper is the single most useful thing you can leave behind.

Dry the container before you reseal it. Sealing a wet container is worse than leaving it open — you have trapped the water in. Wipe it with a cloth, a sock, anything, and give it a minute of air before closing.

And the counterintuitive one: a small drainage hole in the bottom of a container is often better than a failing seal. A container that drains and dries beats a container that fills and stays full. Suggest it to the owner rather than drilling it yourself.

How do you keep your own hides dry?

Container choice, orientation and one habit. In that order of importance.

Buy the container, do not improvise it. Purpose-made screw-top waterproof containers with an intact gasket massively outperform food containers, and the cheap food tub is the origin of most soaked logs. If a hide matters to you, the container is where the money goes.

Orient it lid-down or on its side. Water that lands on a container has to go somewhere, and a horizontal upward-facing lid is a collection point. Simply tipping the same container changes its lifespan dramatically. This is free and it is the biggest single improvement available.

Get it off the ground. Ten centimetres of elevation out of the leaf litter avoids the wet layer where water pools and where damp is constant. Under an overhang rather than beneath a drip line matters just as much.

Double-bag the log. A zip bag inside the container is a second seal and costs nothing. Waterproof paper inside a zip bag inside a good container is functionally indestructible.

Add a desiccant sachet. The silica packets that come in shoeboxes and vitamin bottles handle the condensation problem that no seal can solve. Replace them on maintenance visits.

Say the container size and type in the listing. A finder who knows to expect a small screw-top will reseal it properly. A finder who has no idea what they are handling will not.

Do a wet-season maintenance run. The transition from summer to autumn is when the year’s water damage happens, and a single circuit of your hides now prevents most of the Needs Maintenance logs you would otherwise get over the next few months. Bring spare logs, spare bags, a cloth and a couple of replacement containers.

Respond to maintenance flags promptly even if you cannot fix them yet. An owner note saying thanks, I will get there next weekend keeps finders engaged and stops a cache spiralling toward archival. Silence is what kills caches, not water.

FAQ: Wet Cache Questions, Answered

Can I log a find if the logbook is unsignable?

Yes. Log Found, explain that the log was too wet to sign, and attach a photo of the container. This is standard practice and owners overwhelmingly accept it.

Should I log Needs Maintenance or just mention it?

File the attribute. It is the only version that creates a visible flag on the listing, and it is not rude — it is the mechanism the system provides for exactly this.

Can I replace the container myself?

Empty it, dry it, replace the log, improve the bagging — yes, and thank you. Swap the container itself only after asking the owner, because container type is sometimes part of the cache design.

What if the cache is clearly abandoned?

Log what you find honestly and file the maintenance flag. Reviewers act on a pattern of unaddressed flags over time, and that process works. Do not archive-by-neglect it yourself by removing the container.

Is pencil really better than pen?

On damp paper, considerably. Graphite marks a wet surface where ink beads, spreads or tears through. A short pencil belongs in every cache bag for this reason alone.

Why do my caches only flood in autumn?

Because the day-night temperature swing is at its largest and the ground is at its wettest at the same time. That combination drives the breathing effect that pulls water past seals. Tipping the container and adding desiccant addresses both halves of it.

TL;DR:

• Log Found and file Needs Maintenance. Both. The flag is what gets it fixed; the find keeps the data honest.
• Never sign a soaked log with a pen — photograph the container instead and say so in the log.
• Empty, dry, re-bag and re-seat the lid. Ask before swapping the container, never move the hide.
• Most flooding is temperature cycling and orientation, not a poured-in leak. Tipping a container lid-down fixes more than a new gasket.
• Waterproof paper, a zip bag and a silica sachet cost almost nothing and end the problem.

A repair kit that fits in a jacket pocket turns a ruined find into a two-minute fix for everyone behind you.
