When a pressure washer loses pressure after a few seconds, the pump is almost certainly fine — the machine handed you the pressure that was already stored in the hose, then discovered it could not get water in as fast as it was pushing water out. Four things produce that exact timing: a supply that

Roof soft cleaning means applying a cleaning solution to the roof at roughly 40 to 100 PSI — garden-hose pressure — letting it sit for fifteen to twenty minutes so it kills the algae, moss and lichen in place, then rinsing gently. The water never does the cleaning. It only carries the chemistry up and

Gutter and drain cleaning means clearing the whole path the water takes — trough, outlet, downspout and the drain at the bottom — because a blockage anywhere in that chain puts the water on your wall. Scoop the trough by hand, clear the outlet, flush the downspout from the bottom up, then run a hose

The correct way to remove moss off a roof is to kill it where it sits and leave it there. Spray a dilute chlorine bleach solution from a pump sprayer — 50:50 with water is the usual trade starting point from a laundry-strength jug, though the strength that reaches the roof depends on what you

Driveway cleaning and sealing is one job in two halves with a wait in the middle: wash the slab, then give it at least 24 hours of dry weather before any sealer touches it — 48 to 72 hours if the day is humid, the slab is shaded, or it rained at any point. That

The right patio cleaning solution is decided by what the slabs are made of, not by what the stain looks like — roughly 2% sodium hypochlorite with a surfactant for algae on concrete and block paving, oxygen bleach where the colour is precious, a pH-neutral stone soap on limestone, sandstone and porcelain, an alkaline degreaser

Cleaning rust stains off concrete is a chemistry problem, not a pressure problem. Rust is iron oxide that has dissolved into the slab and re-formed inside the pores, so there is nothing sitting on the surface for water to push off. It takes an acid that can grab hold of iron and carry it away

A siding cleaning solution is three things — sodium hypochlorite, a surfactant and water — and for a typical house wall it wants to land near 1% chlorine at the surface, which is about one part 12.5% pool chlorine to eleven parts water, with a couple of ounces of surfactant stirred in per five gallons.

How do I remove efflorescence from brick? Dry-brush it off with a stiff fibre brush on a warm, dry day, before any water touches the wall — and only reach for a proprietary masonry cleaner if the brush leaves something behind. That is the whole removal job, and it takes about ten minutes on a

Cleaning concrete floors properly comes down to one question you answer before you fill a bucket: is the slab sealed, unsealed, polished or painted? Sealed and polished floors get dust-mopped and damp-mopped with a pH-neutral cleaner and nothing acidic. Unsealed slabs want a stiff brush, an alkaline cleaner and as little standing water as you
