From time to time Arthur will need to be cleaned but if you get him wet he'll stop singing for ever. Never fully immerse him in water, don't go near the washing machine, bath or shower - he's not that sort of bear!
There are several ways listed below of to keep him clean and pristine. But remember ...
Method 1 - Vacuum for the dusty bearIf Arthur has picked up dust or grit, then vacuuming on a low setting will go a long way to revitalising his fur.
Method 2 - Baking Soda for grime and odourIf Arthur is a bit grimy and starting to smell a little (he is a bear after all) then here's a great way to sort it out: Put him in a plastic bag and tip in half a cup of baking soda over him. Seal the bag and shake it so that the baking soda gets everywhere it can. Take him out and wipe him down with a dry cloth, toothbrush, or vacuum to get rid of the powder.
Method 3 - Bear soapSometimes the dirt is just too much, so soap and water is the only remedy. However do not immerse him in water, nor put him in the washing machine. Either, stir your liquid soap and warm water in a bowl then take only the bubbles and rub them into his fur, or, put a soap and warm water solution in a hand spray bottle and spray on the dirty area. You could include a fabric softener. Leave a while then wipe down with a damp cloth. FInally, rub him down with a dry cloth and leave to air.
