Caring for the Kitchen Floor

Grit, water and the mop

1. Get the grit up first.Sweep with a soft broom, or vacuum on the hard-floor setting with the rotating beater bar switched off — on wood and vinyl it throws grit and leaves marks. In a busy kitchen, every day or two. Mopping over grit just drags it around.
2. Damp, not wet.A flat microfibre mop, wrung out until it is barely damp, with a pH-neutral cleaner made for your floor at the dilution on the bottle. More cleaner is not cleaner floor; it is a sticky film that holds the next lot of dirt.
3. Spills now, not later.Water, oil and juice are wiped up when they happen. On wood and laminate the danger is water reaching a seam; on stone and grout it is a stain or an etch.
4. Mats in the right places.One inside every outside door catches most of the grit before it reaches the kitchen. A washable mat in front of the sink catches drips. Check that the mat’s backing is safe for your floor (see vinyl below).
5. Felt under everything that moves.Felt pads on every chair and stool leg, replaced when they wear thin or pick up grit — a gritty felt pad is sandpaper.

Hardwood and engineered wood

What they search at midnight “can you use vinegar on hardwood floors” — not as a habit; use a cleaner made for finished wood.

• Clean with a cleaner made for finished wood floors. A damp microfibre mop and the floor maker’s recommended cleaner. Vinegar, ammonia and all-purpose sprays dull the finish over time, and oil soaps, waxes and “shine” products leave a film that makes the next recoat fail to bond.
• No steam mops, no wet mops. Heat and water driven into the seams swell the edges of the boards.
• Know which finish you have. Most factory-finished floors have a polyurethane-type surface coat, and everything above applies. Floors finished with a penetrating oil are different: they want the maker’s own soap and an occasional maintenance oil, and the wrong cleaner leaves them patchy.
• Hold the humidity. Wood floor makers generally ask for roughly 30–50% relative humidity, give or take by product. In a Canadian winter, gaps between boards are normal shrinkage and close again in summer; a humidifier keeps them small. Edges higher than the middle of the board — cupping — mean moisture from below, and in a kitchen the first suspect is a leak under the dishwasher or the sink.
• Sun changes wood. Most species change colour with light, so move rugs and mats now and then to avoid a pale rectangle, and use blinds on a strong south or west window.
• Recoat before it wears through. When the traffic lane between the sink and the stove looks dull but the colour is still intact, a light sanding of the finish and a fresh coat renews it. Wait until the wood is grey and worn, and it is a full sanding back to bare wood — which an engineered floor can only take as many times as its wear layer allows.

Laminate: the surface is tough, the seams are not

A laminate floor is built a lot like a melamine cabinet: a tough printed surface on a fibreboard core, and the core swells if water gets in at an edge. The rules are the same.

• Mostly dry cleaning. Sweep or vacuum, then a microfibre mop that is only just damp, with a laminate cleaner. Never pour water or cleaner onto the floor.
• Never steam, never wet-mop. Steam and standing water are driven into the joints and swell the core, and a swollen laminate edge does not go back down — exactly like a swollen cabinet edge.
• No wax, no polish. Laminate is not meant to be polished; shine products leave a slippery, streaky film.
• Scratches and dents. Small ones take a colour-matched laminate repair kit or wax stick. A badly damaged plank can be replaced; a floating floor can be opened from the nearest wall, or a single plank cut out and replaced by a fitter.

Luxury vinyl: waterproof on top, fussy about mats and steam

• Damp-mop with a pH-neutral cleaner. Vinyl tolerates water on its surface far better than wood or laminate, but water that gets under the floor at the walls or around a dishwasher can still reach and damage the subfloor. Wipe up what you spill.
• Check before you steam. Most vinyl plank warranties exclude damage from steam mops and from excessive heat; the heat can warp planks and loosen joints. Unless your floor’s care sheet allows it, do not.
• No rubber-backed mats. Rubber and latex backings react with vinyl and leave yellow stains that do not come out, and several warranties name them as an exclusion. Use mats sold as safe for vinyl floors.
• No wax, no polish, nothing abrasive. The factory wear layer is the finish. Scouring powder and abrasive pads dull it for good.
• Sun and heat. Strong sun through a big window can fade vinyl and make planks expand; blinds help both. Never put anything hot straight on it.

Tile is tough. The grout is the weak spot.

• Porcelain and ceramic. Almost any pH-neutral floor cleaner, and a steam mop if you like. The tile itself is the least fussy surface in the house.
• Cement grout gets sealed. Ordinary cement grout is porous: it soaks up grease and stains, which is why the grout in front of the stove goes dark first. Seal it after it has cured, then whenever water darkens it instead of beading. Epoxy grout does not need sealing.
• Go easy on acids. Vinegar and acidic cleaners slowly eat cement grout. A grout brush and an alkaline or oxygen-based grout cleaner lift the grime without the damage; bleach can discolour coloured grout.
• Natural stone is a different animal. Marble, travertine and limestone are etched by vinegar, lemon and many bathroom cleaners. Use a pH-neutral cleaner made for stone only, keep grit off it, and reseal it on the schedule its installer gives.
• Keep spare tiles. A cast-iron pan dropped edge-first will crack a tile. One tile can be cut out and replaced, but only if a few spares from the same batch were kept in the basement. The same goes for spare planks of any floor.

A tile backsplash follows the same rules, with one addition: grout behind the cooktop collects grease fastest, so it gets the soapy wipe weekly and the sealer first.

Leaks, heavy appliances and dropped pans

• Moving the fridge or range. Small appliance wheels carrying a few hundred pounds dent wood, tear vinyl and crack tile, and dragging is worse. Lay a sheet of hardboard or thin plywood in front of the appliance and walk it out onto the sheet. Unplug first; for a fridge, mind the water line behind it, and for a range, its anti-tip bracket has to be re-engaged when it goes back.
• Leak alarms. A small battery water alarm on the floor of the sink cabinet, behind the fridge and beside the dishwasher costs little and turns a slow leak into a beep, rather than a cupped floor and a swollen cabinet found months later.
• Pets and plants. A water bowl or a plant pot sat directly on a wood or laminate floor slowly marks it; stand it on a tray.
• Grease near the range. Cooking splatter lands on the floor as well as the cabinets. A damp, soapy wipe in front of the stove, more often than the rest of the floor, stops it turning into the sticky patch that holds grit.

The floor and the cabinets, together

• A floating floor and fixed cabinets. Laminate, click vinyl and floating engineered floors are designed to move with the seasons. Most of their makers ask for the floor to stop at the cabinets, with its expansion gap hidden behind the toe kick, rather than run underneath and be pinned by them. A few rigid-core products allow it. The installation instructions for your exact floor decide, so read them before the cabinets go in — the renovation order page shows where flooring falls in the sequence.
• A new floor raises the room. Lay a new floor in front of an old dishwasher and it may never come out again. Check the height first: the dishwasher page has the numbers.
• Protect it during the work. While cabinets go in, cover the finished floor with heavy paper or cardboard, taped to itself rather than to the floor’s finish, and carry boxes rather than sliding them. Lift a cabinet into place; dragging one across a new floor is how the first scratch happens.
• The toe kick is your friend. When you mop, the toe kick is the one cabinet part that meets the water. Do not leave the mop sitting against it, and dry any puddle at its base.
