I live in Northern VA and wash my X whenever most every weekend in the winter. If the outside temp's above 40 degrees, I've been able to wash my X as follows: Fill a bucket with warm water from a bathtub, add car wash soap, put on your 'chemicalproof gloves' you buy at Home Depot ($3-4), dip your sponge/wash mitt in the bucket and wash the X--top to bottom. I use a hose to rinse, but hand-rinsing with a few buckets of water will work. Dry as you would normally.
