How many bin bags do I need for a party?

As a rough guide, allow 1 heavy-duty bin bag per 10-15 guests for a buffet-style party. Formal sit-down meals generate more waste per head. Always buy more than you think you need - having extras is better than running out.

How long does party cleanup take?

For a casual indoor party of 30-40 guests, expect 1-2 hours of cleanup with 2-3 helpers. Outdoor parties take longer due to wider area. Formal events generate more washing up. Kids parties create more mess per guest.

How can I speed up party cleanup?

Set up recycling and waste bins during the party so guests can self-sort. Use disposable plates and cups where possible. Clear away dishes as you go rather than leaving everything until the end. Recruit 2-3 friends to help.

What cleaning supplies do I need for a party?

Essential supplies: heavy-duty bin bags, all-purpose cleaner, cloths/paper towels, washing-up liquid, floor mop or vacuum. For outdoor parties add: outdoor broom, waterproof bags. For kids parties: stain remover for carpets and upholstery.
