The Hand-Washing Method (Recommended)

Step 1: Sort Your Bricks

  • Sort by color if desired (prevents color transfer)
  • Keep small pieces separate from large ones

Step 2: Prepare Cleaning Solution

  • Fill basin with lukewarm water (40°C maximum)
  • Add a small squirt of mild washing-up liquid
  • Mix gently to create light suds
  • Never use hot water – it can warp plastic

Step 3: Wash the Bricks

  • Place bricks in soapy water
  • Swish gently with your hands
  • Let soak for 10-15 minutes for heavily soiled bricks
  • Use soft brush for stubborn dirt
  • Pay attention to crevices and underside studs

Step 4: Rinse Thoroughly

  • Drain soapy water
  • Rinse bricks under cool running water
  • Ensure all soap residue is removed
  • Use colander to make rinsing easier

Step 5: Dry Completely

  • Spread bricks on clean, dry towels
  • Pat dry with another towel
  • Air dry completely (24-48 hours)
  • Ensure thorough drying before storage
  • Never use hairdryers or radiators (heat damage risk)

The Washing Machine Method (Use with Caution)

When to Use:

Only for basic bricks without stickers, prints, or electronic components. Not recommended for valuable or vintage pieces.

Instructions:

  • Place bricks in pillowcase or mesh laundry bag
  • Tie securely to prevent escape
  • Use delicate/gentle cycle
  • Cold water only (30°C maximum)
  • Small amount of mild detergent
  • No spin cycle if possible
  • Air dry completely

Risks:

  • Small pieces could escape bag

Special Cleaning Situations

Sticky Residue:

  • Use small amount of rubbing alcohol on cloth

  • Rinse with water immediately
  • Test on inconspicuous piece first

Permanent Marker:

  • Try rubbing alcohol or nail polish remover (acetone-free)
  • Use sparingly and test first
  • May not remove completely
  • Rinse thoroughly after treatment

Yellowed Bricks:

  • Yellowing is often permanent (UV damage)
  • Hydrogen peroxide solution may help slightly
  • Sunlight exposure can worsen yellowing
  • Prevention is better than cure

Mold or Mildew:

  • Soak in solution of water and white vinegar (1:1)
  • Scrub with soft brush
  • Rinse thoroughly
  • Dry completely to prevent recurrence

What NOT to Do When Cleaning LEGO

Never Use:

  • Hot Water: Warps and damages plastic
  • Dishwasher: Too hot, can melt or warp bricks
