Cleaning covers things like:

• dust, dirt, limescale, soap residue, grease,
• food spills, stains on worktops,
• dirty floors, dirty bathroom and kitchen surfaces.

Damage is something that cannot be fixed by cleaning alone, for example:

• burns or deep scratches on furniture or floors,
• broken glass, tiles or fixtures,
• mould caused by very poor ventilation and long-term neglect,
• permanent stains on mattresses, sofas or carpets.

Normal cleaning costs are your responsibility as a tenant. Damage can lead to repair or replacement costs, which may be charged separately or deducted from your deposit.
