Baking soda for cleaning concrete is a weak option for almost every stain you will find on a slab — not because it is gentle, but because the two things it is physically capable of doing are both feeble, and neither of them is the thing a driveway stain actually requires. That is not the
Cleaning decks with bleach is a trade-off rather than a technique: chlorine bleach kills mildew and algae faster and more reliably than anything else you can buy in a jug, and the same oxidation that kills them keeps going into the wood underneath — so the right mix is the weakest one that works, and
The only eco friendly gutter cleaning solutions worth the shelf space are warm water with a soft brush, a plain surfactant house-wash, sodium percarbonate where something is genuinely growing, and — outside face only, mixed weak — dilute sodium hypochlorite. Everything else in that part of the aisle is one of those four with a
To remove mildew from cement, sweep the slab bone dry, damp it down, apply a diluted sodium hypochlorite solution, let it sit ten to fifteen minutes without drying out, agitate with a stiff synthetic brush, then rinse. Five steps, and the first one does more long-term work than the other four combined. That is not
Cleaning driveway with bleach kills whatever is growing on the concrete and does absolutely nothing to whatever has been driving on it — which is the entire problem, because a driveway usually goes grey from traffic rather than green from algae, and once the surface is wet the two are indistinguishable. Before you mix anything,
Cleaning siding with bleach works, but a wall is not a driveway stood on its end — gravity decides the dwell rather than your watch, which is why a vertical surface wants a weaker mix than a slab, applied wet and re-wetted, never applied strong and rushed. Almost everything written on this subject is a
DIY concrete cleaning is worth doing yourself right up to the point where water flow, not effort, becomes the limit — and on a homeowner electric machine that point arrives at roughly 1.6 gallons per minute. Below that line you are the equal of any contractor on a patio, a path or a set of
Cleaning and staining wood deck boards is not one job — it is two jobs with a gap between them, and almost every failed deck finish is a gap that was handled badly: the stain went onto boards that were still wet inside, still standing on torn fibre, or had been left bare in the
A house siding cleaning brush is the only tool in the whole job that removes anything mechanically — the solution kills the growth, the rinse carries it off, and the bristles are the only part that actually touches what is stuck. Everything else you point at the wall is chemistry arriving at speed. That is
Cleaning stains from concrete is a diagnosis problem before it is a cleaning problem. Almost every concrete stain belongs to one of four families — organic, petroleum, metallic or mineral — and each family responds to one kind of chemistry while ignoring the other three completely. Work out which family you are looking at, pick
