Any idea of the best way of cleaning a tennis bag? Bought a used one recently as this particular brand/model is no longer made, but its a bit manky inside and out and because its mostly white, the dirt shows up really easily! Tempted to fold it up and throw it into the washing machine but concerned that its just going to destroy the bag, damage the interior foam padding too much etc. Anyone tried dry cleaning a tennis bag? Or is this going to be a case of alot of elbow grease and detergents? If so, any particular types of detergents recommended?
