Forty small hacks across every room. Grouped by category for quick scanning; most take under a minute to implement.

Kitchen (10)

1. Freeze herbs in olive oil (ice cube trays)
2. Store knives in a drawer with a knife block, not a counter block
3. Cast iron — never soap, salt-scrub instead
4. Microwave half a lemon in water to loosen splatter
5. Tape uncorked wine bottle tops to keep them vertical in the fridge
6. Mason jars as airtight storage — better than plastic
7. Put plastic wrap on before opening the spice jar for the first time; the magnetic seal helps
8. Store coffee beans in the freezer, grind fresh
9. Let meat rest after cooking — every time
10. Invest in one great cutting board; ignore the 6-piece sets

Bathroom (8)

11. Dryer sheet removes soap scum from glass shower doors
12. Denture tablets clean toilet bowl rings overnight
13. Shower-curtain liner weekly in the washing machine
14. Over-door hooks for towels when the bathroom lacks rail space
15. Mirror defog: tiny amount of shaving cream wiped across glass
16. Squeegee after every shower — prevents 90% of water spots
17. Baking soda in toilet tank — cheap deodoriser
18. A clear jar for cotton swabs replaces the ugly package

Cleaning (8)

19. Vinegar + water spray replaces half of store-bought cleaners
20. Baking soda before vacuuming carpet — deodoriser
21. Dish soap + warm water cleans most surfaces safely
22. Lint roller picks up dust in lampshades
23. Toothbrush scrubs grout
24. Rubber gloves in the dryer pull pet hair from delicate fabric
25. Wipe switch plates and door handles weekly — high-touch spots collect dirt invisibly
26. Microfibre cloths — one for glass, one for general, colour-code

Organisation (8)

27. One junk drawer, strict limit
28. Tension rods under sinks for hanging bottles
29. Magazine holders on cabinet doors for foil/wrap
30. Drawer dividers for every drawer over 2 inches deep
31. Labelled bins in the pantry
32. One-in, one-out rule for anything you buy more of
33. Hooks on bedroom door for tomorrow's outfit
34. Basket at the bottom of the stairs for items going up

Maintenance (6)

35. Photo of every utility box, meter, and filter when you move in — label and file
36. Change HVAC filter quarterly, set a calendar reminder
37. Caulk bathroom edges every 3 years — prevents mould
38. Check smoke detector batteries at daylight savings transitions
39. Label breakers before you need them
40. Keep a small running list of "when something needs fixing" items; batch them one weekend a year

Forty hacks. Pick 10; the cumulative time and money saved across a year is substantial.
