Before you start cleaning an assembled Lego set, it’s essential to prepare yourself for the task ahead. This involves gathering the necessary supplies, choosing a suitable workspace, and taking photos of the set for reference or documentation purposes.

Gather Necessary Supplies:

  • Mild dish soap: Opt for a gentle dish soap that won’t damage the Lego bricks or their decals.

Choose A Suitable Workspace:

Whether you have just completed a challenging Lego build or have a collection of assembled sets, here are some essential tips to help you maintain clean Lego sets:

Avoid Eating Or Drinking Near Them

Accidents happen, but when it comes to Lego sets, it’s best to avoid eating or drinking near them. Here’s why:

Keep your Lego sets in a designated play area away from food and beverages to minimize the risk of accidental spills or stains.

Keep Away From Pets Or Small Children

While Lego sets are great for sparking creativity and imagination in children, it’s essential to keep them away from pets or small children when it comes to maintaining their cleanliness. Here’s why:
