LEGO is more than just toys – for many, it is a true passion and sometimes even an investment. Old LEGO sets that have survived decades often have their own collector's value. However, to ensure that they retain their charm and functionality, it is worth knowing how to properly repair and maintain them. In this article, we will learn how to take care of your classic LEGO sets and restore them to their former glory.
1. Check the condition of your LEGO bricks
The first step in preserving old sets is to assess their condition. There are a few key aspects to consider:
- Scratches and abrasions: Old pads may have visible signs of use.
- Discolouration and fading: LEGO plastic can discolour over time, especially if exposed to sunlight.
- Deformation or mechanical damage: Check that the pads are not bent, cracked or damaged, which could affect their connection.
2. Cleaning LEGO bricks
Regular cleaning is essential to keeping your LEGO sets looking new. Here are some proven methods:
-
Hand Wash: It is safest to hand wash the blocks in lukewarm water with a mild detergent. Avoid high temperatures – hot water can warp the plastic. For hard-to-reach areas, such as the insides of the blocks, use a soft toothbrush.
-
Dishwasher: While many collectors use the dishwasher to clean LEGO, this method requires caution. Use dishwasher nets to keep the bricks from getting lost, and set the dishwasher to a gentle cycle without drying. However, it’s important to note that this method isn’t recommended for particularly valuable or delicate bricks.
-
Alcohol cleaning: Isopropyl alcohol is great for removing grease and dirt, but should not be used on printed surfaces as it may damage them.
3. Removing discoloration and fading
Old LEGO bricks that have been exposed to the sun for years can lose their color. However, there is a way to restore them to their former glory.
-
Hydrogen peroxide solution: You can try soaking the discoloured pads in a hydrogen peroxide solution (e.g. 3% solution), which will often restore the colour to the plastic. However, be careful to rinse the pads thoroughly after this process.
-
Dyeing Bricks: While not for everyone, more advanced collectors sometimes choose to dye faded bricks with special paints. However, dyeing LEGO bricks can reduce their collectible value.
4. Repair and replacement of components
In some cases, damaged LEGO elements can be repaired or replaced. Here are some suggestions:
-
Use of glue: Although LEGO generally does not recommend using glue, some collectors choose to glue pieces that are particularly susceptible to falling apart. Remember, however, that gluing can be difficult to undo, so it is best to use it only as a last resort.
-
Buying Spare Parts: It is worth knowing that LEGO offers the possibility of buying spare parts for some sets, even older ones. Online platforms such as BrickLink offer a wide selection of elements for classic sets, which allows you to replace damaged parts.
5. Storing old LEGO sets
Proper storage is crucial to protect your kits from damage:
-
Avoid sunlight: Direct sunlight causes colors to fade and can weaken the plastic. Store the kits in a dark place or in clear UV-protected boxes.
-
Protect from moisture: Moisture can cause mold to grow and damage the stickers on the pieces. Store the blocks in a dry place, preferably in airtight containers.
-
Suitable temperature: LEGO bricks are best stored at room temperature. Avoid places where they may be exposed to large temperature fluctuations.
6. Collectible value – how to ensure uniqueness
For collectors of vintage LEGO sets, original condition and completeness of the set are key factors in determining value. Therefore, attention to detail, such as well-preserved stickers and instructions, can make a huge difference.
Over time, even the most carefully maintained LEGO sets may require some repairs. However, with the tips above, you can significantly extend the life of your LEGO set and enjoy it for years to come. Patience and attention to detail will help preserve the charm and value of classic LEGO sets.
