Post-renovation dust cleanup - new extension finished

Just finished our rear extension (finally!) and there's fine dust EVERYWHERE from the building work. Need help with a thorough dust and wipe-down of all surfaces, windowsills, skirting boards. The builders did a basic clean but it needs proper attention. We're on Victory Boulevard near the Alamein line crossing. Have all cleaning supplies, vacuum, and microfibre cloths. Perfect for detail-oriented helpers!
