Many kitchen sink caddies are dishwasher safe, particularly simple plastic and stainless steel ones, which is useful because a sink caddy, holding wet sponges, brushes and washing-up liquid by the sink, gets slimy, grimy and can grow mold, so being able to put it in the dishwasher makes cleaning it easy. However, it depends on the material and design: a basic plastic or stainless caddy usually takes the dishwasher, while caddies with suction cups, certain coatings, rubberized parts, or other materials may be better hand washed, so you should check. Either way, the important thing is to clean the caddy regularly, by dishwasher or by hand, because it is a damp spot that collects grime and needs keeping hygienic. Our Best Kitchen Sink Caddies compares five of them.

Why sink caddies get dirty and need cleaning

A kitchen sink caddy is the holder that sits by or over the sink to keep sponges, scrubbing brushes, dish soap and the like tidy and to let them drain. Because of this, it is constantly wet and holds wet, soapy, sometimes food-soiled items, so water, soap scum, food residue and grime collect in it, and the damp environment means it readily develops slime, pink or black mold and smells if not cleaned, often collecting dirty water in its base. It is one of the grimier spots in the kitchen precisely because it is always damp and holds the dirty cleaning tools.

So a sink caddy genuinely needs regular cleaning to stay hygienic, which is why being dishwasher safe is a handy feature, it makes that regular cleaning easy. The caddy collecting slime and grime is normal given its wet, dirty job, and the point is to clean it often enough that the grime and mold do not build up. Understanding that a caddy is a damp grime-magnet that needs regular cleaning frames the dishwasher question: whether it is dishwasher safe mainly affects how easily you can do that necessary regular cleaning, not whether you need to.

Which caddies are dishwasher safe

Whether a sink caddy is dishwasher safe depends on its material and design. Simple caddies made of dishwasher-safe plastic or of stainless steel are generally dishwasher safe, since those materials tolerate the dishwasher’s heat and detergent, and many such caddies are labeled as dishwasher safe, which makes cleaning them as easy as popping them in with a load. For a basic plastic or stainless caddy, the dishwasher is usually fine, and it is a convenient way to clean off the slime and grime.

The ones to check are caddies with other materials or features: those with suction cups or rubberized grips (which can degrade or lose suction with dishwasher heat), coatings or finishes that could be affected, or made of materials not suited to the dishwasher, may be better hand washed, as may caddies that are part of a fixed over-the-sink or mounted fitting. Some caddies also have a removable drip tray that is dishwasher safe even if the whole unit is awkward. So check the maker’s guidance or the material, since a basic plastic or steel caddy is typically dishwasher safe, while suction, coated or complex ones may need hand washing.

Cleaning it, dishwasher or by hand

If your caddy is dishwasher safe, cleaning it is easy: pop it in the dishwasher periodically with a normal load, which cleans and helps sanitize it, removing the slime and grime, and then let it dry. Doing this regularly keeps the caddy hygienic with minimal effort, which is a good reason to choose a dishwasher-safe one. Rinsing out loose grime first and placing it securely in the dishwasher helps.

If the caddy is not dishwasher safe, or you prefer, hand washing is straightforward: wash it in warm soapy water, scrubbing off the slime, soap scum and grime with a brush, getting into the base and any drainage holes where dirty water and gunk collect, and for mold or stubborn grime, clean it with a solution of diluted bleach, vinegar or a suitable cleaner to kill the mold and freshen it, then rinse and dry. A caddy with a removable drip tray is easier, as you can empty and wash the tray where the dirty water gathers. Whichever method, the key is to actually clean it regularly, since the caddy’s damp, grimy nature means it needs it. So dishwasher-safe caddies make the needed cleaning easy, and hand washing does the same job for others.

Keeping it hygienic and the bottom line

To keep a sink caddy hygienic, clean it regularly, by dishwasher or hand, before heavy slime and mold build up, empty any standing dirty water from its base often (a caddy that drains well and does not pool water stays cleaner), and let it and the items in it drain and dry rather than sitting in a puddle. Choosing a caddy with good drainage and a removable tray, and in a dishwasher-safe material if you want easy cleaning, makes keeping it clean simpler. Also keep the sponges and brushes it holds clean, since dirty tools add to the grime.

So the bottom line is that many kitchen sink caddies, especially plastic and stainless steel ones, are dishwasher safe, which is a genuinely useful feature given how grimy caddies get, making regular cleaning easy, but you should check your caddy’s material and design, since suction-cup, coated or complex ones may be better hand washed. Either way, the caddy needs regular cleaning to prevent slime, mold and smells, so whether it is dishwasher safe mainly determines how you clean it, not whether you must. So check the material, use the dishwasher if it is safe, hand wash if not, and above all clean the caddy regularly to keep it hygienic.

The short answer

Many kitchen sink caddies are dishwasher safe, especially simple plastic and stainless steel ones, which is a handy feature because a caddy, constantly wet and holding sponges, brushes and dish soap, collects slime, soap scum, food residue and mold and needs regular cleaning, so being able to put it in the dishwasher makes that easy. But it depends on the material and design: a basic plastic or steel caddy usually takes the dishwasher, while caddies with suction cups or rubberized grips, certain coatings, or other materials, and fixed over-sink fittings, may be better hand washed, so check the maker’s guidance. If it is dishwasher safe, clean it periodically in a normal load; if not, hand wash it in warm soapy water, scrubbing the slime from the base and drainage holes and using diluted bleach or vinegar for mold, then dry it. Either way, the key is to clean the caddy regularly and keep it draining and dry, since its damp, grimy nature means it needs regular cleaning to stay hygienic, with dishwasher-safe simply making that easier.

Common questions

Are kitchen sink caddies dishwasher safe?

Many are, especially simple plastic and stainless steel ones, which is handy since caddies get slimy and grimy and need regular cleaning.

Why do kitchen sink caddies get so dirty?

Because a caddy is constantly wet and holds wet, soapy, sometimes food-soiled sponges and brushes by the sink, so water, soap scum, food residue and grime collect in it, and the damp environment readily develops slime, pink or black mold and smells, often with dirty water pooling in the base.

How do you clean a sink caddy that is not dishwasher safe?

Hand wash it in warm soapy water, scrubbing off the slime, soap scum and grime with a brush and getting into the base and drainage holes where dirty water and gunk collect, and for mold or stubborn grime clean it with diluted bleach, vinegar or a suitable cleaner to kill the mold and freshen it, then rinse and dry. A caddy with a removable drip tray is easier, since you can empty and wash the tray where the dirty water gathers.

Which sink caddies should be hand washed?

Those with materials or features the dishwasher could harm: caddies with suction cups or rubberized grips that can degrade or lose suction with dishwasher heat, ones with coatings or finishes that could be affected, materials not suited to the dishwasher, and fixed over-the-sink or mounted fittings. A basic plastic or stainless steel caddy is usually dishwasher safe, so check the material and design, and when unsure hand wash it.

How do you keep a sink caddy hygienic?

Clean it regularly, by dishwasher if it is safe or by hand, before heavy slime and mold build up, empty any standing dirty water from its base often, and let the caddy and the items in it drain and dry rather than sit in a puddle. Choosing a caddy with good drainage and a removable tray helps, as does keeping the sponges and brushes it holds clean, since its damp, grimy nature means regular cleaning is what keeps it hygienic.
