Spring cleaning evolved in temperate climates: open the windows after a long winter, air things out, deep clean areas neglected during cold months. Bangkok doesn't have winter. Here's what a proper tropical-climate annual deep clean looks like.
The Bangkok calendar equivalent
For Bangkok residents, the logical 'annual reset' timing is February–March — after Lunar New Year and before Songkran. Weather is cooler and drier, aircon use is moderate, and you can actually open windows without humidity flooding in.
What to focus on annually
- All aircon deep cleaning (filters, coils, drain lines)
- Hot water heater descaling
- Washing machine hot wash cycle (removes biofilm)
- Dishwasher cleaning cycle
- Fridge coil vacuuming (saves electricity)
- Curtain washing (accumulated year of dust and PM2.5)
- Mattress deep clean or replacement if 7+ years old
- Closet reorganization and clothing purge
- Furniture pulled out for behind-cleaning
What not to bother with
- Dusting for 'winter accumulation' — it's the same dust every week
- Opening all windows to air out — not useful in humidity
- Rotating winter/summer wardrobes — Bangkok doesn't need this
- Polishing wood floors heavily — tropical humidity undoes it quickly
The tropical-specific annual tasks
- Regrout or reseal bathroom grout annually
- Reseal or replace caulk around sinks, tubs, windows
- Mosquito screen replacement or repair
- Outdoor metal furniture rust treatment
- Termite inspection (if ground-level)
- Balcony waterproofing inspection
Professional services worth bundling
A deep cleaning combined with aircon service, sofa cleaning, and pest inspection in the same week is more efficient than spreading them through the year. Most cleaning services offer multi-service bundles with a 10–20% package discount.
