LEGO® bricks are made from durable plastics designed to last for decades, which is exactly why pre-owned sets are such a good idea. But a common question is: are second-hand bricks clean and safe?
The risks with unchecked second-hand LEGO
- Dust, pet hair or food residue from previous storage.
- Mixed pieces from other sets or non-LEGO "compatible" bricks.
- Small missing parts that can frustrate a build.
How REBLOXE prepares every set
Every set we sell goes through our strict quality-control process: each piece is checked, then cleaned and disinfected before it ships. The product page states the grade and exactly what's included, and every set carries the REBLOXE Verified badge.
Small parts and young children
Regardless of whether a set is new or pre-owned, most LEGO sets contain small parts and are not suitable for children under 3. For toddlers, look at DUPLO sets, which are designed for their age group. Always follow the age indication on the box.
Want to clean them again at home?
You can hand-wash bricks in lukewarm water (below 40°C) with a little mild soap, then let them air-dry. Never use a dishwasher or hot water, which can warp pieces, and don't wash electronic parts or stickered pieces. See our full guide on cleaning LEGO at home.
Family favourites
The Passenger Train 60197 and the Friendship Tree House 41703 are popular pre-owned picks for families.
