Rinse in fresh water and then put them in soapy water to neutralise the acid
I use Lectric Washing Soda ($4 per Kg @Coles) for the warm soapy water, the Alkaline pH of 11 is quite effective at neutralising acids.
Got this tip from bottle of AliBrite Aluminium cleaner (hydroflouric & sulfuric acids)
"Before the advent of modern cleaning products, washing soda was the main product used for doing the laundry and household cleaning.
Lectric Washing Soda is made from 100% natural sodium carbonate and contains no phosphates, dyes, colourants or fragrance"
