Lagerung und Pflege: 40 Unit Blocks und Fraction Blocks

Quick answer

Store wooden blocks in open bins sorted by shape or size, clean them with a damp cloth and mild soap only when needed, and keep them away from moisture and direct heat. For 40 unit blocks, use a shallow bin with dividers so pieces stay visible and accessible. Fraction blocks benefit from a compartmented tray to keep small parts together.

Wooden blocks are an investment in your child's play, and a little care keeps them in good shape for years. Whether you have a 40-piece unit block set, fraction blocks, or a mix of construction toys, a simple storage and cleaning routine prevents lost pieces and damage.

This guide walks you through seven steps to organize, clean, and maintain your block collection. You'll also find tips on what to avoid, like soaking blocks in water or storing them in damp basements. With the right habits, cleanup becomes quick and blocks stay ready for the next build.

Why block storage and care matter

Wooden blocks are durable, but they can warp, crack, or grow mold if exposed to moisture. Storing them loosely in a deep toy box makes it hard for children to find the piece they need, which can lead to frustration and abandoned play. A thoughtful storage system keeps blocks accessible and protects your investment.

Proper care also extends the life of the finish. PlanToys blocks are made from chemical-free rubberwood with organic pigments, so harsh cleaners or prolonged water exposure can dull the colors or damage the wood. Gentle cleaning and dry storage are usually all that's needed.

• Rotate blocks occasionally to check for splinters or loose parts.
• Keep a small brush or dry cloth nearby for quick dusting.

Step 1: Sort blocks by type and size

Before you store anything, sort your blocks into groups. Unit blocks come in standard shapes like rectangles, squares, triangles, and cylinders. Fraction blocks are smaller and often used for math play. Keeping them separate makes it easier to find what you need and prevents tiny pieces from getting lost among larger ones.

If you have multiple sets, consider sorting by set first, then by shape. For example, keep all 40 unit blocks together, and store fraction blocks in their own container. This also helps if you want to rotate toys or lend a set to a friend.

• Use a muffin tin or egg carton as a temporary sorting tray.
• Involve your child in sorting—it's a fun matching activity.

Step 2: Choose the right containers

Clear plastic bins or open wooden crates work well because they let you see what's inside. Avoid airtight containers unless the blocks are completely dry; trapped moisture can encourage mold. Shallow bins are better than deep ones because children can reach in without dumping everything out.

For 40 unit blocks, a bin that's about 12 inches wide and 6 inches deep holds the set without overcrowding. Fraction blocks are best kept in a compartmented box or a small bin with dividers. If you prefer bags, use cotton drawstring bags that allow airflow.

• Label bins with pictures or words for easy cleanup.
• Stack bins on a low shelf so kids can access them independently.

Step 3: Establish a daily reset routine

The easiest way to keep blocks organized is to make cleanup part of the play routine. Set a timer for five minutes before dinner or bedtime and have everyone help put blocks back. A consistent reset prevents piles from accumulating and makes the next play session more inviting.

If your child is reluctant, turn cleanup into a game: 'Can we put all the triangles in the bin before the song ends?' This builds habits and reduces your own workload. For older kids, a checklist taped to the bin can serve as a reminder.

• Use a small dustpan and brush for quick tidy-ups.
• Keep a 'lost pieces' jar for stray blocks to be reunited later.

Step 4: Clean wooden blocks properly

Most of the time, a dry microfiber cloth is enough to remove dust. For sticky messes, wipe with a cloth dampened with a mix of mild soap and water, then dry immediately with a towel. Never submerge wooden blocks in water or put them in the dishwasher—moisture can cause warping and crack the finish.

For disinfecting, use a diluted vinegar solution (1 part white vinegar to 3 parts water) on a cloth, then wipe dry. Avoid bleach or alcohol-based cleaners, which can damage the paint and wood. If a block has a deep groove, a soft toothbrush helps dislodge debris.

• Test any cleaner on a hidden spot first.
• Let blocks air-dry completely before storing.

Step 5: Protect blocks from moisture and heat

Store blocks in a dry, indoor area away from radiators, windows with direct sun, and damp basements. Humidity can cause wooden blocks to swell or grow mold, while heat can dry them out and lead to cracks. A bedroom or playroom shelf is usually ideal.

If you live in a humid climate, consider a dehumidifier or silica gel packets in the storage area. Avoid storing blocks in airtight plastic bags for long periods; wood needs to breathe. A breathable cotton bag or open bin is better.

• Check blocks after a humid spell for any signs of mold.
• Rotate stored sets every few months to inspect them.

Step 6: Handle wear and tear

Even with care, blocks can develop rough edges or splinters over time. Lightly sand any rough spots with fine-grit sandpaper (200-400 grit), then wipe away dust. If the finish is worn, you can rub in a food-safe oil like coconut oil or beeswax to restore luster—but check with the manufacturer first.

For PlanToys specifically, the chemical-free rubberwood and water-based pigments are designed to be safe, but refinishing may void warranties. If a block is severely damaged, it's best to retire it rather than risk splinters. Keep an eye on frequently used pieces like the 2-in-1 wrench and screwdriver from the Construction Set.

• Inspect blocks monthly for loose parts or cracks.
• Sand only if you're confident in your technique; otherwise contact the brand.

Step 7: Rotate and refresh your collection

If you have a large block collection, rotate sets every few weeks to keep play fresh. Store unused sets in a labeled bin out of reach. This also gives you a chance to clean and inspect them. Rotation works well with themed sets like the Urban City Blocks, which can complement unit blocks.

When introducing a rotated set, display it invitingly on a low shelf or play mat. A small basket of loose parts can spark new ideas. Remember that fewer blocks often lead to deeper play, so don't feel pressured to keep everything out at once.

• Use a calendar reminder for rotation if you have many sets.
• Involve your child in choosing which set to bring out next.

Your 7-step block care routine

1. Sort blocks by type and size: Group unit blocks, fraction blocks, and specialty pieces separately. Use a muffin tin or egg carton as a sorting tray. Checkpoint: All small pieces are contained and visible.
2. Choose clear, shallow containers: Use clear bins or open crates so kids can see inside. For 40 unit blocks, a 12x6-inch bin works well. Fraction blocks need compartments. Checkpoint: Containers are easy for your child to access and put away.
3. Establish a daily reset routine: Set a 5-minute timer before transitions. Turn cleanup into a game or song. Label bins with pictures for non-readers. Checkpoint: Blocks are back in their bins at least once a day.
4. Clean with a damp cloth only: Wipe with mild soap and water, then dry immediately. Never submerge or dishwash. For disinfecting, use diluted vinegar. Checkpoint: Blocks are completely dry before storage.
5. Store away from moisture and heat: Keep in a dry, indoor area. Avoid basements, direct sun, and radiators. Use breathable bags, not airtight plastic. Checkpoint: Storage spot stays dry year-round.
6. Inspect and repair wear: Sand rough edges with fine-grit sandpaper. Re-oil only if recommended by the manufacturer. Retire severely damaged blocks. Checkpoint: No splinters or loose parts remain.
7. Rotate sets regularly: Swap out sets every few weeks. Store unused sets in labeled bins. Display the current set invitingly. Checkpoint: Your child engages with the 'new' set within a day.

Block sets that benefit from good storage
