Can you wash magnetic tiles in water?

No. Wipe them with a damp cloth instead. Submerging tiles lets water past the seams, where it rusts the internal magnets and weakens their hold. Connetix's own care guidance is a damp cloth without chemicals.

Can magnetic tiles go in the dishwasher?

Never. Dishwasher heat warps the plastic, and a warped tile no longer sits flush against its neighbours, which permanently weakens builds. Hand-wipe only.

How do you disinfect magnetic tiles?

Use a child-safe disinfectant wipe wrung nearly dry, and test one tile first, since manufacturers including Connetix officially recommend plain water only. Avoid bleach and alcohol, which degrade the plastic, and dry the tiles immediately afterwards.

How to clean magnetic tiles without wrecking them

The whole method fits in a sentence: wipe with a damp cloth, dry straight away, and never submerge them. Everything else in this guide is why, and the two mistakes that actually kill tiles.

The routine

Everyday grime:a soft cloth dampened with plain water, wiped over both faces. This handles fingerprints, dust and most playroom residue. Connetix's own guidance is exactly this: damp cloth, no chemicals.
Sticky messes (playdough, food, marker): a few drops of mild dish soap in water, cloth dipped and wrung out well, wipe, then a second pass with a clean damp cloth.
Sanitising (after illness, or for shared and classroom sets): a child-safe disinfectant wipe, wrung nearly dry. Worth knowing: manufacturer guidance (Connetix included) favours plain water and no chemicals, so wipe a single tile first and check the finish. Avoid bleach and alcohol outright; both degrade the plastic.
Dry immediately with a towel, then let them air out fully before they go back in the tub. Moisture left on seams is how water finds its way inside.

The two ways people actually ruin tiles

Soaking them.Tiles look sealed but the seams are not waterproof, and the magnets inside can rust: water that seeps in corrodes them, weakens the hold, and can stain the inside of a translucent tile permanently. Connetix's own FAQ warns exactly this. No sink, no bath, no "quick rinse" under the tap. This applies double to budget tiles, whose seams are looser to begin with.

The dishwasher. Heat is the second enemy. Dishwasher temperatures warp the plastic, and warped tiles never sit flush again, which ruins the magnetic contact. The same logic applies to leaving tiles baking on a windowsill or in a hot car: prolonged heat and direct sun fade colours and can distort pieces.

The wipe-down is also your safety check

Cleaning is the natural moment to inspect, because you are already handling every tile. Look for cracks, chipped corners, loose seams and any tile whose magnets rattle or feel loose. A damaged tile goes in the bin, not back in the tub: exposed magnets are the one genuine hazard this toy has. Our safety guide covers why that matters and what to do if a magnet is ever swallowed. A practical rhythm for a daily-use set: quick wipe when it looks grubby, deeper clean and full inspection every month or two.
