Some marks need another clean. Others are staining, wear, failed materials or maintenance issues that stronger products will not safely fix. Use this guide to work out what you may be looking at — and what to do next.
Vacated properties often contain years of wear, mineral deposits, aged sealants, damaged coatings, moisture effects and permanent staining. Knowing the difference matters — especially when deciding whether to keep cleaning, document the condition or raise a repair issue.
Select the area, what you can see and how the issue behaves. We'll give you a practical starting classification and the safest next step. This is guidance, not a remote diagnosis — materials and underlying causes can look similar.
Choose the closest area.
Choose the description that most closely matches the issue.
This final clue helps distinguish surface residue from staining, wear or an underlying condition issue.
Appearance alone can be misleading. These comparisons show why something that still looks marked after cleaning is not necessarily remaining dirt.
Soap residue usually sits on the surface. Long-term mineral deposits can etch or cloud glass and may remain after the removable residue is gone.
Surface mould can often be treated. Dark staining embedded through aged silicone, splitting or separation can indicate failed sealant rather than remaining surface dirt.
Grout is porous and can hold discolouration even after surface soil has been removed. Missing, cracked or deeply discoloured grout is not solved by endlessly increasing cleaning strength.
Finger marks and light surface grime may clean away. Missing paint, scuffs through the coating, patchy touch-ups, moisture staining and aged paint are surface-condition issues.
Loose soil and some spills respond to extraction cleaning. Permanent dye changes, bleaching, wear, fibre damage, old stains or pile distortion may remain.
Grease films can be removed, but swollen board, peeling laminate, worn coatings and stains absorbed into damaged material are not ordinary cleaning residue.
Carbon and grease can be stubborn, but damaged enamel, scratched glass, corrosion and permanent heat discolouration are different from removable cooking residue.
Staining beneath sinks, around windows or at cabinetry edges can point to historic or active moisture. Cleaning may improve the surface but cannot correct the source or reverse swollen material.
Repeated scrubbing and stronger chemicals can turn a cleaning question into actual surface damage. A simple decision process is safer.
Glass, natural stone, laminate, painted surfaces, stainless steel and grout tolerate very different products and techniques.
Use a suitable product and method, follow its directions and test an inconspicuous area where appropriate.
If residue is transferring or reducing, cleaning may still help. If the actual finish is changing or damage is appearing, stop.
If the surface is clean but staining, deterioration or a defect remains, photograph it rather than repeatedly attacking the material.
If an issue appears to be pre-existing, permanent or maintenance-related, your condition reports and photographs help preserve the context. Record observable facts rather than trying to diagnose the cause yourself.
At move-in, document what you received. Before handover, compare the property against that starting condition and photograph what you are returning. ExitMaid's interactive resources can guide both processes.
Entry Condition Report Tool →No. A persistent mark can be permanent staining, material ageing, mineral etching, wear, a maintenance issue or damage. “Not cleanable” and “renter-caused damage” are not the same conclusion. Document what you can observe and compare it with the property's earlier condition.
No. Stronger is not automatically better. Incompatible chemicals, abrasives and repeated aggressive treatment can damage coatings, stone, metal, glass and sealants. Stop if the material itself appears to be changing.
No. Superficial mould may respond to cleaning, but recurring growth can relate to moisture, ventilation or another underlying issue. Mould can also permanently stain porous grout and silicone. Cleaning does not remediate an underlying moisture source.
No. Professional cleaning removes cleanable soil and residue; it cannot reverse age, wear, scratches, failed coatings, etched glass, damaged grout or other permanent material changes.
Do not treat it as a cleaning problem. Document what you can safely observe and follow the appropriate repair or maintenance process with the rental provider or agent. Urgent repair rules may apply depending on the issue.
