1. Dust First with a Microfiber Cloth or Duster

Always start by removing loose dust. A microfiber cloth or extendable duster traps particles instead of spreading them. Pay attention to:

  • Top edges where baseboards meet walls
  • Corner seams
  • Decorative trim grooves

For high areas, use a ladder or adjustable duster. This step prevents muddy streaks when applying cleaner later.

2. Use a Mild Cleaning Solution

Mix warm water with a gentle dish soap or vinegar solution (1:1 ratio). Avoid bleach or ammonia, which can discolor surfaces. For heavy grime, try:

  • Magic Eraser (for scuffs)
  • Rubbing alcohol (for sticky residue)
  • Pet-safe cleaner (for urine stains)

Test cleaners on a hidden spot first. Spray lightly—oversaturation warps wood.

3. Scrub Crevices with a Toothbrush or Soft Brush

A toothbrush or detail brush reaches tight spaces. For stubborn dirt:

  • Dip the brush in cleaning solution
  • Gently scrub grooves and corners
  • Wipe with a damp cloth

For painted trim, avoid abrasive tools to prevent chipping.

4. Wipe Down with a Microfiber Cloth

After scrubbing, wipe surfaces with a damp microfiber cloth to lift dirt. Change rinse water frequently to avoid redepositing grime. For large areas, use a flat mop with a cleaning pad.

5. Dry Thoroughly

Moisture left on baseboards attracts dust and can warp materials. Use a dry cloth or towel to remove excess water. Speed up drying with a fan in humid climates.

6. Apply a Protective Finish (Optional)

For long-term shine, use a furniture polish or car wax on wood trim. This creates a barrier against dirt. Avoid silicone-based products—they attract dust.

7. Maintain Weekly

Prevent buildup by:

  • Dusting baseboards during regular cleaning
  • Spot-cleaning spills immediately
  • Using a dryer sheet (externally linked) to repel dust
