Cleaning your chestpack

Give your 'Geek' some TLC now & again.  DO NOT MACHINE WASH. Using a wet cloth rub in some vanish stain remover or just use soapy water/ rinse cloth/ repeat a couple of times then rinse it all off properly under a tap.  Gently clean the inside if needed with just a soapy cloth or sponge, then wipe the soap off with a wet cloth or sponge, don't use anything abrasive on the inside or outside.  Leave to dry inside & out thoroughly before using again.  Once dry it helps a little if you put a little silica packet inside till you use it again as they absorb & trap excess moisture.
