Yup....been a few years since doing mine but it's starting to get pretty bad and we're supposed to have some nice weather for the next few days. Have an extendable soft brush and may just use soap and water on the crappy vinyl siding then spray it down in the spring to help it from growing green again for awhile.....or just add some bleach to the soap and water. I guess the price of bleach is only going to go higher.
