how to clean the outside of a small house for around $10
4 costco sized bags of baking soda (one for each side) and a jug of white vinegar for the windows.
we have aluminum siding. which i hate, but it was there when i bought the house and it's not the top priority for money right now (hello new furnace, you are just the amuse bouche).
on the white aluminum siding on the north side of the house it gets green. it's a slow process, but it has hit critical mass. it looks bad. it's embarrassing to have a house turning green.
bust out a LOT of baking soda, a mixing bowl you can carry around, a hospital glove (already on hand, not part of the budget) and a hose. make stiff paste, rub until your arm is about to disconnect. hose down. voila.
i love baking soda in so many ways. now there is +1. to be clear, i only did one section of the north side, but you could totally do the whole house and have pretty pristine siding. it doesn't take off super duper stains, but it does remove organic matter better than simple green or comet. they key is you have to let the wad of paste do the scrubbing. no brushes or sponges.
of course bonus points for not dumping chemicals into your yard.
if you're feeling ambitious, do the windows with vinegar and newspaper.
kindred souls, speak up about your baking soda love.
