One of the biggest advantages of porcelain tiles is how easy they are to look after. Unlike natural stone, porcelain doesn’t need sealing. Unlike carpet, it won’t harbour dust or allergens. Unlike wood, it won’t warp or stain. But “easy to maintain” doesn’t mean “no maintenance at all.” Knowing the right cleaning methods—and avoiding the wrong ones—will keep your porcelain tiles looking as good as the day they were fitted.

What is the best way to clean porcelain tiles?
For most porcelain tiles, a simple routine is all you need to keep them looking their best. Start by sweeping or vacuuming. Remove loose dirt and grit before you mop. Left on the surface, grit acts like sandpaper underfoot and can dull matt finishes over time. Mop with warm water and a pH-neutral tile cleaner. A small amount is all porcelain needs for routine cleaning. pH-neutral cleaners are gentle on both tiles and grout, and they won’t leave a dulling residue. Avoid bleach-based cleaners for regular use. It can discolour grout over time—and it’s unnecessary for day-to-day cleaning. Do not use vinegar or acidic cleaners. Despite being widely recommended online, acidic solutions can etch the surface of some porcelain finishes and damage grout. Stick to pH-neutral products instead. Use a microfibre mop. Microfibre cleans effectively without leaving streaks or residue, and it’s kinder to your tiles than traditional cotton mops.
Deep Cleaning and Stubborn Stains
Most porcelain cleaning issues fall into a few common categories. Here’s how to tackle each one safely and effectively.
Grout haze after installation – A white film on new tiles is usually grout residue. Use a specialist grout haze remover—available from most tile suppliers—and follow the product instructions. Do not scrub with abrasive pads, as these can scratch the surface.
Grease and cooking stains (kitchen floors) – Kitchen floors take a beating. A solution of warm water and mild detergent will cut through grease without damaging the tile. Mop as usual, then rinse with clean water.
Rust stains – Rust marks are usually caused by metal furniture legs or tools left on wet tiles. A specialist rust remover for tiles is the safest option. Do not use steel wool or abrasive scrubbers—they will scratch porcelain.
Hard water marks – Common in bathrooms, these white mineral deposits build up over time. A limescale remover safe for porcelain will lift them without damaging the tile. Check the product label to confirm it’s suitable for use on porcelain and grout.
Matt tile cleaning – Matt porcelain shows marks and residue more easily than gloss. The most common cause of streaky matt tiles is using too much cleaning product. Use less cleaner, mop with warm water, and buff dry with a microfibre cloth for a clean, even finish.
Cleaning Outdoor Porcelain Tiles
Outdoor porcelain is tough, but it gets dirty differently. Algae, moss, leaf stains, and general weathering are the main culprits—not the everyday grime you see indoors.
Prevention: keep it swept- The easiest way to keep outdoor porcelain looking good is to stop problems before they start. Sweep regularly and clear leaf debris as it falls. Organic matter left on the surface encourages algae and can leave stubborn stains over time.
Routine cleaning – use a stiff brush and warm soapy water to clean outdoor porcelain. Scrub the surface with a stiff-bristled brush and a solution of warm water and mild detergent, then rinse with clean water.
Can you use pressure washers to clean outdoor porcelain tiles? Yes, but with care. Keep the nozzle at least 30cm from the surface and use a fan spray, not a pencil jet. A narrow jet can damage grout joints, especially if they’re older or poorly maintained.
Looking After Your Grout
Grout is the weak point of any tiled surface. Unlike porcelain, grout is porous—it absorbs moisture, dirt, and stains. Looking after it properly will help to keep your tiles looking clean and fresh for years.
Seal grout after installation – Sealing grout is recommended, especially in kitchens and bathrooms. A good-quality grout sealer creates a protective barrier that makes cleaning easier and prevents staining. Follow the product instructions and allow the grout to cure fully before sealing.
Clean grout lines with a grout-safe cleaner and a stiff brush – Use a specialist grout cleaner or a mild solution of warm soapy water. Scrub along the grout lines with a stiff brush—an old toothbrush works well for small areas. Rinse thoroughly with clean water.
Avoid bleach on coloured grout – Bleach will lighten coloured grout over time. If you need to tackle mould or stubborn stains on coloured grout, use a grout cleaner designed for the job.
Re-seal grout every 1–2 years in wet areas – Showers, around baths, and behind sinks take the most moisture. Re-sealing grout in these areas every year or two keeps it looking fresh and prevents mould from taking hold.
If grout is beyond saving, re-grout – Discoloured or crumbling grout can make even beautiful tiles look tired. Re-grouting is a straightforward job that can transform the look of existing tiles without replacing them. Rake out the old grout, clean the joints, and apply fresh grout—it’s one of the most cost-effective ways to refresh a tiled surface.
What NOT to Do
A few common mistakes can damage porcelain tiles or grout. Here’s what to avoid.
Never use abrasive scourers or steel wool – They will scratch the surface of porcelain, even on matt or textured finishes. Stick to soft cloths, microfibre mops, and non-abrasive brushes.
Never use wax, polish, or oil-based products – These leave a residue that attracts dirt and dulls the finish. Porcelain doesn’t need polishing—it’s designed to stay looking good with simple cleaning.
Do not use steam cleaners unless grout is in good condition – Steam can force moisture behind loose or damaged grout, leading to damp problems or tile lifting.
Avoid homemade tile cleaner recipes – Online recipes often include vinegar, lemon juice, or baking soda. Vinegar and lemon juice are acidic and can damage grout and certain tile finishes. Baking soda is mildly abrasive and can scratch over time. Stick to pH-neutral tile cleaners designed for the job.
Conclusion
Porcelain tiles are one of the lowest-maintenance flooring and wall options available. Routine sweeping and mopping with a pH-neutral cleaner is all most tiles need. For deeper cleaning, match the product to the problem—grout haze remover for new tiles, degreaser for kitchen floors, limescale remover for bathrooms—and avoid harsh or abrasive methods. Look after your grout, and your tiles will look as good in ten years as they do today.
Frequently Asked Questions
