Always test the cleaning agent in an inconspicuous area first to ensure the wall coating is not affected. Oil stains can be wiped with a diluted neutral detergent, while water stains can be removed with a slightly damp cloth. Never mix bleach with other chemicals. If the stain is too large or has penetrated deep into the surface, stop DIY and seek assistance from 壹家壹清潔專家.
Identifying the source of wall stains
There are many types of wall stains; you must confirm the nature of the stain before proceeding to determine the cleaning strategy:
- Oil stains: Common in kitchens; usually require a neutral detergent to break down the oil.
- Water stains: Mostly caused by seepage or condensation; the source of the problem should be addressed first.
- Fingerprints and dust: Surface dirt that can usually be removed with a dry cloth or slightly damp sponge.
- Pen marks: Depending on the nature of the pigment, choose solvents cautiously to avoid damaging the wall paint.
- Observe the state of the stain edges
- Touch to determine dryness
- Confirm the wall material such as emulsion paint or wallpaper
Preparation for wall cleaning
The wrong tools will wear down the wall coating, so preparation cannot be sloppy:
- Sponge: Use a soft product with good absorbency.
- Microfiber cloth: Used for final drying to avoid streaks.
- Neutral detergent: Use a mild formula, avoiding strong acids or alkalis.
- Protective gear: Wear gloves to protect your skin.
- Prepare clean water and two cleaning cloths
- Dilute the detergent with water according to the product manual
- Prepare a step ladder rather than standing on unstable furniture
Correct cleaning steps and key points
The cleaning process must be careful to prevent wall discoloration or paint peeling:
- Material testing: Apply a small amount of diluted cleaning solution in an inconspicuous corner and wait for it to dry to check for discoloration or paint peeling.
- Top to bottom: Wipe from high to low to prevent water stains from running onto already cleaned areas.
- Moderate pressure: Wipe gently in circular motions; do not use excessive force, which may wear down the coating.
- Immediate drying: Use another dry cloth to absorb moisture; avoid leaving the wall in a damp state for a long period.
- Final check: After it is completely dry, confirm that the color matches the rest of the wall. If there is residue, do not repeat cleaning forcibly.
