What do you use to clean out spider webs in eaves prior to painting. Up here in the mountains, we have lots of daddy-long-leg spiders and they just pack the eaves between the overhanging rafters full of their webs. Can't pressure-wash up there too much because of open venting into the attic. They are really sticky! Hitting them with a broom just seems to roll them up into thick strings which adhere to the T1-11 siding real well. What to do? Anything that will dissolve them?
