Ceramic tile

A glass glaze that nothing penetrates, set in porous cement grout that does. The tile is easy and the joints are the whole job.

What ceramic tile can and cannot take

  • Heat Use with care
  • Water and soaking Tolerates it
  • Acids, including vinegar Use with care
  • Strong alkalis Tolerates it
  • Solvents Use with care
  • Chlorine bleach Use with care
  • Abrasives Use with care

Always test on a hidden area first and let it dry before you treat the visible mark.

General rules for ceramic tile

Nothing absorbs into a glazed face, so a milk mark wipes off with warm soapy water and no technique at all.

Everything that follows is about the joints. Cementitious grout is porous and mildly alkaline, and acid dissolves it, which rules out vinegar and limescale removers on a tiled surface even though the tile itself would not care.

Work the joints with a soft brush and a mild alkaline or neutral cleaner, rinse properly, and dry the floor.

Check the label

The glaze on a ceramic tile is glass and nothing soaks into it, so the tile itself is almost never the problem. The grout between the tiles is cement, it is porous, and it is what holds a stain. Treat a tiled surface as grout with tiles in it.

Stains on ceramic tile

A glazed ceramic tile is a fired clay body with a glass layer on the face.

The glaze is impermeable

So the stain has nowhere to go and a wipe removes it. Glazed tile is one of the easiest surfaces in the house.

The grout is not

Cementitious grout is porous, absorbs readily and is dissolved by acid. On a wall or floor, the total length of exposed grout is considerable, so in practice a tiled surface behaves like grout with hard patches in it.

Scratching the glaze is permanent

Abrasive pads and scouring powders dull a glaze, and a dulled area holds dirt and shows every time the light catches it.

Sealing the grout is the real fix

The tile trade recommends sealing cementitious grout, and a sealed joint stops most of this happening at all.

  1. Cleaning grout, Tile Council of North America trade body

    Tile trade body guidance that grout manufacturers do not advocate the use of acids because acids attack the cement in the grout, that grout is alkaline based and is dissolved by acids, that mildly alkaline cleaners are preferred over acidic ones, that oil and wax based cleaners leave a film that attracts dirt, that alkaline cleaner not properly rinsed leaves a sticky residue, and that cementitious grout should be sealed to prevent staining.

  2. Quarry tile care and maintenance, Daltile manufacturer

    Tile manufacturer guidance that quarry tile is sealed before grouting and resealed regularly to protect against staining, that routine cleaning is multi purpose products or plain soap and water, that no rinse enzymatic and acid based cleaners are avoided because the combination of heat, food contamination and cleaner makes the grout soft and permanently damages it, and that a soft bristle brush suits the textured surface.

  3. Sick happens: how to get vomit out of carpet, National Carpet Cleaners Association trade body

    UK carpet cleaning trade body method for vomit: scrape solids with a blunt spatula or spoon, apply equal parts white vinegar and water, blot gently working towards the middle of the mark rather than outwards, never scrub because that drives the vomit deeper and damages the carpet, use only a small amount of warm water on a dried mark, and expect rehydrating it to release the smell again so ventilate.
