I'm in the UK, so it could be a bit different but I bought
dry cleaning sheets from woollite on amazon and you can put them in the
tumble dryer on low for 20 mins, I often use it to refresh
wool and silk scarves sometimes reusing the sheets with a little lavender oil.
And when it is your turn to wash it (accidents do happen), it can be done in a standard machine and
tumble dried on no - heat setting — there's none of the hand washing fuss traditionally associated with
wool products.
