Care instructions

🧼 RIWI® foam building blocks are super easy to keep clean:
• Washable in the washing machine or by hand at 86°F
• Use a mild detergent – no fabric softener
• Gently squeeze out wet foam and let it air-dry lying flat – ideally on a drying rack with good airflow

That way, the blocks stay hygienic – even after wild playtime!

☀️ Sunlight advice: Since we deliberately avoid harmful substances, RIWI® foam can be sensitive to UV rays.
Feel free to use the blocks outdoors – but store them in the shade or protected after playtime.
Long exposure to direct sunlight may cause visible changes like yellowing – totally harmless, but noticeable.
