I found THE BEST cleaner for our home's exterior and had to share. We've used Wet n Forget in the past... which works fine, but no where near as good as this Home Armor Outdoor Cleaner. This stuff worked so well - it looked like we had re-painted our siding! And it's so much cheaper!! It hooks up to your garden hose, you spray it on, then rinse it off for an almost immediate clean. 10 out of 10! Also linking the Windex Outdoor spray we use to clean our windows. It works the same way - just hook it up to your garden hose to spray it on then rinse away the grime. LTKHome
