In fact, with the passage of time these narrow spaces tend to become discoloured, accumulating dirt that can also affect the hygiene of the room overall.
So the gap between tiles is the real critical point, and needs regular care and cleaning. This problem is more noticeable and occurs more quickly in the most heavily-used areas – such as kitchens, bathrooms and entrance halls – because they’re constantly exposed to fats and greases, limescale, water or dirt brought in from outdoors.
So now we’ll take a look at how to clean the joints between tiles effectively, alternating routine methods and solutions for dealing with intensive soiling, with exactly the advice you need to conserve the quality and elegance of your porcelain stoneware over time.
How to clean the joints between tiles: routine methods
Constant cleaning of joints is fundamental to keep them looking good and prevent dirt from building up to the point where it’s difficult to remove. In porcelain stoneware floors, maintenance is simplified by the technical characteristics of the material itself, which is compact, non-porous and therefore easy to clean: this means you can focus on the joints, the only part likely to absorb dirt.
The natural remedies most widely used for cleaning joints between tiles include sodium bicarbonate, vinegar and lemon. A mixture of three tablespoons of sodium bicarbonate, two of vinegar and half a glass of warm water, applied with a soft brush, dissolves superficial dirt without harming surfaces. The bicarb has a light, gentle abrasive action, the vinegar helps to remove limescale deposits and has a sanitising effect, and the lemon removes grease and leaves a pleasantly fresh fragrance.
These methods are safe, inexpensive and environment-friendly, but they’re not very effective against deep stains, discolouring or seriously blackened joints. In these situations, it’s best to turn to neutral pH professional cleaners, specifically formulated for stoneware and cementitious grouts. Diluted in as instructed and applied with a soft cloth or non-abrasive sponge, they remove dirt in depth with no risk of scratching, keeping the floor as immaculate and gleaming as on the very first day.
Cleaning porcelain stoneware joints with neutral cleaners
The most effective solution for keeping the floor in tip-top condition and conserving surfaces’ original appearance over time is to use specific neutral cleaners: routine cleaning every two weeks is enough in most parts of the home, while in high-traffic areas like kitchens and entrance halls it’s best to increase the frequency to stop dirt from building up.
Apply the cleaner solution with gentle aids like a microfibre cloth or soft sponge, which can clean thoroughly without risking scratching or damage to the surface. In fact, hard brushes or aggressive cleaning aids might dull the finish and leave the joints looking patchy.
After cleaning, it’s important to rinse quickly with clean water, to remove all product residues. Following this simple rule will maintain the porcelain stoneware’s typical shine and conserve the joints’ natural shade, preventing discolouring or streaks over time.
Extraordinary cleaning of joints: when is it necessary?
Extraordinary cleaning is required when joints become discoloured, have dark stains not removed by ordinary washing or contain mould. This happens most often in the kitchen, where fat, grease and food residues can penetrate in depth, in the bathroom, where damp and limescale can cause blackening, and in outdoor locations exposed to dust and dirt from the environment.
On porcelain stoneware, the non-porous surface allows cleaning products to act effectively and reduces the risk of damage, making the process safer and more effective.
Steam cleaning the joints between tiles
Steam cleaning uses the combined action of heat and pressure to dissolve the dirt residues inside joints, reaching even the deepest deposits. The jet of steam penetrates into the pores of the cementitious grout, removing grease, limescale and mould with no need for chemical cleaners.
For a precise job, it’s a good idea to use specific accessories like pointed nozzles or little synthetic bristle brushes, so you can work along the line of the joints and clean inside even the smallest spaces.
This method’s main benefit is that it sanitises in depth, eliminating bacteria and microorganisms through heat alone, leaving surfaces clean and free from chemical residues. However, the pressure and temperature must be set correctly: an excessively strong jet or too high a temperature could damage fresh or more delicate grouts.
On porcelain stoneware, which is tough and non-porous, steam cleaning provides excellent results, but it must always be performed with due care to conserve the joints’ durability and appearance.
How to whiten the joints between tiles
Discoloured or blackened joints can be restored to their original colour with the aid of simple but effective natural methods.
One very popular method is to use a paste of sodium bicarbonate and hydrogen peroxide: apply it directly to the joint, leave it to act for about 15 minutes then rub gently with a soft brush and rinse with clean water. Otherwise, a mixture of lemon and salt combines the natural bleaching action of citric acid with a gentle abrasive effect, useful for removing superficial stains.
For particularly stubborn dirt, professional whitening products ensure quick, uniform results. Always follow the producer’s instructions to the letter, complying with leave-in times and rinsing thoroughly to eliminate all chemical residues and prevent damage to the material.
Maintenance and dirt prevention
Constant maintenance of joints is fundamental to keep the floor looking good and conserve all its functional qualities.
It’s also vital to deal at once with any fresh deposits such as splashes of liquids, food residues or dust, so they don’t harden in the joint and cause permanent stains. Regular cleaning with delicate cleaners and microfibre cloths keeps joints in good condition and prevents discolouring.
In the case of wood-effect porcelain stoneware, the joints may be narrower and less noticeable, but this doesn’t mean they’re immune to dirt. Actually because they’re so narrow, it’s even more important to use non-aggressive products and gentle cleaning techniques to conserve the surface’s appearance and visual continuity intact.
Mistakes to be avoided when cleaning joints
To keep joints looking good over the long term, don’t use over-aggressive products (unless strictly necessary) as they may corrode the material and cause it to discolour. Similarly, metal-bristle brushes and abrasive utensils may create scratches and damage the grout.
Another bad habit is cleaning too often with unsuitable products that may leave chemical residues on surfaces: over time, these tend to trap even more dirt, leading to deterioration of the floor’s overall appearance.
