Use a soft brush to remove dried playdough from the intricacies of your stamps. Lightly wipe over with a cleaner of your choice using a soft cloth and dry in the sun.
Do not immerse in water or drench in cleaning solutions the wood will warp and swell.
Your wooden items may need a drink with a timber polish every now and then to avoid them splitting and cracking. We use a beeswax and coconut oil polish.
Inspect your products regularly and dispose of thoughtfully any damaged pieces.
