How to clean your bonnet

We rarely think about cleaning our head-dress - and if you wear it daily (as soldiers do) it can get very manky indeed before you notice it.
In this video I show my tried-and-true method for cleaning a bonnet, which works equally well for khaki TOS and balmoral bonnets.
This particular glengarry might well be a century old (good kit lasts a long time) and as it clearly shows the marks of a Sergeants' or officers' cap badge - there isn't a very long list of Sergeant-Pipers in the 1st Bn - it might well have been worn by one of my personal heroes: WO John Gillies MSM or WO1 Ed Essen MBE - in which case I've committed Antiquarian Sacrilege by washing the mud of Vimy and the Somme or the dust of Sicily out of it ( Oops) - but In the absence of provenance I will wear it with pride when I play my pipes (themselves a relic of Tobruk and Alamein)
