What can I fix instead of replacing?

Six things that read as finished and are not. Each page names the limit where its fix stops being a fix, and those limits are the part worth reading twice.

The screw hole that will not hold. Fill the stripped hole with wood and glue says a screw that spins forever has not broken; the hole has, because the fibres it gripped are chewed into fluff. Break wooden toothpicks into the hole until it is packed tight, wet them with yellow wood glue, snap them off flush and let it dry properly before the screw goes back. The order of importance is not the order people remember: the toothpicks are scaffolding, and the glue soaking into the ruined fibres in the wall of the hole is what rebuilds the wood, so a hole packed dry will hold for a while and then will not. Yellow glue over the white in the cupboard for anything carrying weight or living anywhere damp, because the differences that matter are creep, slow movement under a load that never lets up, which is exactly what a door does to a hinge, and water, and yellow resists both better. Too big for toothpicks: matchsticks are harder wood, a golf tee fills a wider hole, and people who do this daily carry chopsticks. The page’s safety line is its own limit: this is for light indoor work, a cabinet door, an interior door, a curtain rail, a loose handle, and not for the hinges of an exterior entry door or anything holding weight or anyone’s safety. Its honest test is not how the repair feels on the day but what happens when it fails: a cabinet door drops open, a front door does something else. And the part worth more than the repair, for anything with a thread: set the screw or bolt in place and turn it the wrong way until you feel it click into the existing thread, then turn it the right way, which is how you stop cross-threading the next one.

The shower you have been blaming on the building. Soak the showerhead before you replace it is six separate conversations finding the problem in the thing you can unscrew by hand. The head comes off hand-tight; drop it in a bowl of white vinegar for an hour, rub the nozzles, tip the grit out of the little screen in the neck. A low-pressure shower is often a clogged one. If it is still a dribble, thirteen separate conversations, the widest agreement on that page, say a new head is an inexpensive change. One correction the people there made about their own words, four times over: what you feel is flow, not pressure, and a head changes how much water comes out and how it is shaped but cannot change the force in the pipe. Renters get a second half: buy your own, fit it, bag the original and put it back when you leave. The caution above all of it: the arm the head screws onto goes into the wall, and forcing it cracks a joint you cannot see, so hand-tight, and if it will not turn, stop.

The jeans, and the grey soles. Patch the jeans from the inside is three separate conversations ironing an adhesive patch onto the inside of the thinning place, where it shows nothing and holds the fabric behind it. The accounts are firm about the limit: the patch is for the thin place before the hole, a beginner’s hand-mend fails under strain, and the honest end of a torn pair is the scrap bag. The eraser works because it sands explains why melamine foam brings white rubber back when sprays cannot: it does not dissolve dirt, it abrades the stained surface layer off, which is also why the same swipe lifts a printed logo. Use it like sandpaper, damp, light passes, on the rubber only, never on paint, prints or delicate finishes, and stop when the white appears rather than pursuing perfection into the rubber. Two honest boundaries there: yellowed is not dirty, and worn out is not dirty either.

The rusty pan, and the permanent marker. Buy the rusty skillet says cast iron is the one piece of cookware that is better second-hand, because nothing that matters about it wears out; scrub the rust off with steel wool or a short vinegar soak, dry it hard, oil it, and you own a pan that outlasts every non-stick you would have bought instead. Five separate conversations make that case and five more make the money case against the cheap non-stick that scratches, flakes and gets replaced every couple of years. The page carries the argument about seasoning, the oven ritual against simply cooking in it, and its decider is what you are starting from: a pan stripped back to grey metal needs a first coat baked on, a pan that arrived black can go to work. Fight the marker with its own solvent says the name is a bluff, because permanent marker is pigment in an alcohol-based solvent, so plain rubbing alcohol dissolves it from most hard surfaces and skin. Test a hidden spot, dab and let it sit, and keep acetone for last because it dissolves things you love. Its one honest defeat is porous surfaces, raw wood, flat paint, unsealed drywall, where the endgame the accounts admit to is sandpaper or a paint roller.

Who this is not for. The skillet page’s safety line comes first for some readers: anyone with hereditary hemochromatosis, or told they store too much iron, should avoid bare cast iron or ask a doctor first, and a chipped old glaze is its own worry. The showerhead page says if every tap in the house runs slow, the head was never the problem and a plumber is the door, and that a tingle from the water or the fittings is a different page that says call today. And the jeans page’s line, checked there against poison-control guidance: never mix bleach with vinegar.
