Most spring cleaning lists you'll find online were written for a northern hemisphere house, where the job is basically dust. Ours is a different job. After a New Zealand winter, what's actually built up in your home is moisture, and the list that matters is the one that deals with where it went: the window joinery, the bottom of the curtains, the inside of the wardrobe on the cold side of the house.
Do that first and the rest is just cleaning.
Pick a dry day and open everything up before you start. Work one room at a time, high to low, finishing each room before you move on. Prioritise the places winter moisture collects: window frames and seals, curtain hems, blind slats, wardrobes on exterior walls, and behind furniture pushed against outside walls. Then do the jobs a weekly clean never gets to, oven and rangehood filter, fridge, shower grout, skirting boards. Floors last, always.
Why a Kiwi spring clean isn't a dusting job
New Zealand houses spend winter shut. Windows closed, heating on in one or two rooms, washing drying inside because it's been raining for a fortnight. All that moisture has to go somewhere, and it ends up on the coldest surfaces in the house.
The numbers are bigger than people think. Consumer NZ puts a single load of washing dried indoors at around five litres of water released into the house, cooking at about three litres a day, and showers and baths at roughly one and a half litres per person per day. Multiply that across a family and a closed-up July and you can see why the window frames are wet every morning.
So by September, a typical NZ home isn't especially dusty. It's damp, and the damp has left evidence in fairly predictable places. That's what a spring clean here is for, and it's why a list that starts with "declutter the pantry" is solving the wrong problem.
Start with the air, not the cupboards
Before you clean anything, open the house up. Windows, doors, wardrobe doors, the lot.
Consumer NZ recommends 10 to 15 minutes each morning as an everyday habit, and running extractor fans for about ten minutes after a shower or cooking. On the day you're actually cleaning, leave everything open for as long as the weather lets you.
This isn't a nice-to-have first step. Everything you're about to do adds moisture, and you want somewhere for it to go. Wiping down a wall in a closed house just moves the water from the cloth to the room.
It's also the reason timing matters more here than the calendar does. There's no point doing this in the first week of September if that week is grey and still. Wait for a run of dry days, even if it means doing it in October.
The winter damp jobs, in order of what we actually find
If you do nothing else on this list, do these.
- Window joinery and seals. Aluminium frames are the coldest surface in most NZ homes, and the rubber seals hold water. Wipe them out, including the drainage channels along the bottom of the frame, which clog and then pool.
- The bottom of the curtains. They hang against that cold glass all winter. Mould along a curtain hem is one of the most common things we see in spring and almost nobody checks for it. Most are machine washable, but read the label, because a lot of NZ curtains are lined and will shrink.
- Blind slats. Same problem, worse surface. Venetians in particular collect condensation and dust together, which sets into a film that needs wiping rather than dusting.
- Inside wardrobes on exterior walls. No airflow, cold wall, closed door for three months. Take everything out, wipe the back wall, and leave the doors open for a day.
- Behind furniture against outside walls. The couch, the bed head, the chest of drawers. Pull them off the wall and look. If there's mould, our guide to getting rid of mould on walls covers the method, including why you should never scrub it dry.
Cleaning the mould off and calling it done. If it's back in the same corner by June, that spot has a moisture problem, not a cleaning problem, and no amount of spring cleaning fixes it. The clean is worth doing. Just don't expect it to be the answer on its own, because the wall will tell you otherwise next winter.
Room by room
One room at a time, finished before you move on. High to low in each one, because dust falls and doing the floor first means doing it twice.
Kitchen. Oven, including the racks and the door glass. The rangehood filter, which is usually the single grimmest thing in the house and often dishwasher safe. Inside and behind the fridge. Cupboard fronts and handles, particularly around the bin. The splashback grout.
Bathrooms. Shower glass and grout, extractor fan cover, which collects a surprising amount of lint. Behind the toilet properly. Check the silicone along the bath and shower tray, because that's where winter mould sets in and it's the one that sometimes can't be scrubbed back.
Bedrooms. Wardrobes as above. Under the bed. Wash or air the duvet and pillows, and flip the mattress. Skirting boards and door frames, which never get touched in a weekly clean.
Living areas. Light fittings and ceiling fans, tops of picture frames and shelves, then the couch, then the floor. Window reveals while you're there.
Everywhere. Light switches and door handles, which is the highest-contact and least-cleaned surface in any house. Skirtings. The top edge of every door, which everyone forgets and which is always worse than you expect.
Carpets, couches and the soft stuff
Soft furnishings hold a winter better than hard surfaces do, which is why a house can look clean and still smell like August.
Vacuum the couch properly, including under the cushions and into the seams. If there are marks, check the tag before you put anything wet near it, because water on the wrong fabric leaves a permanent ring. Our guide to cleaning a fabric couch covers the cleaning codes and the over-wetting trap.
Carpets are the other one. A winter of wet shoes, closed windows and a heat pump running is hard on them, and vacuuming only lifts what's on the surface. Whether it's worth getting them extracted depends on how long it's been, which we go into in how often carpets actually need cleaning.
Windows are worth doing at this point too, inside and out, because you've just spent three months looking through them at the rain. The streak-free method is mostly about what you dry them with.
What's not worth your Saturday
Spring cleaning lists have a habit of padding. A few things we'd leave off:
- Decluttering as part of the same job. It's a worthwhile task and a completely different one. Mixing them is how a one-weekend clean becomes a four-weekend sort-out that ends with boxes in the hallway.
- Washing walls top to bottom. Spot-clean the marks. A full wall wash is a big job with very little visible payoff unless the walls are genuinely grubby.
- Buying a product for every surface. Most of this is warm water, a bit of detergent and clean cloths. The cloths matter more than the spray does.
- Doing it all in one heroic weekend. Splitting it across a few weekends by room gets it finished. The single-weekend version usually stalls somewhere around the second bathroom.
When it's worth handing over
Honestly, a spring clean is one of the most DIY-able jobs there is. It's time and effort rather than skill or gear, and if you've got the weekends you don't need us for it. We'd rather say that than pretend otherwise.
Where it does make sense to get someone in:
- Carpets. Hot-water extraction pulls the water back out, which is the part a home machine struggles with. Wet carpet in a cold NZ house is how you end up with a musty lounge in October.
- High or awkward windows. Anything involving a ladder above single-storey height isn't worth the risk for a bit of glass.
- You've genuinely run out of weekends. The commonest reason people book a deep clean, and a perfectly good one.
- You're selling. Different standard and a different list, which our pre-listing checklist covers.
If you're weighing up whether this is a deep clean or just a thorough regular one, the difference between the two is worth two minutes before you book anything. And if the real problem is that the house never quite stays on top of itself, that's a rhythm question rather than a spring question, which we cover in how often you should actually be cleaning.
