How to Clean an Ashtray: Glass, Ceramic, Metal and Silicone

An ashtray gets dirty fast, and a dirty one smells worse than the smoking itself. Ash, tar, and oily residue build up in the corners, and the longer they sit, the harder they are to remove. The good news is that cleaning is quick with the right method for the material.

What You Need

• Warm water and dish soap
• An old toothbrush or small brush
• Isopropyl alcohol (for stubborn residue)
• Baking soda (for stains and odour)
• A cloth or paper towels

The Basic Method (Works for Most Ashtrays)

1. Empty out all ash and butts, ideally into a sealed bag or bin.
2. Rinse under warm water to remove loose ash.
3. Wash with dish soap, scrubbing corners with a brush.
4. Rinse thoroughly and dry with a cloth.

Make it a habit to empty the ashtray daily so residue never gets a chance to harden.

Cleaning by Material

Glass Ashtrays

Glass is the easiest to clean because it’s non-porous. Soap and water handle most of it. For stuck-on residue, a cloth soaked in isopropyl alcohol wipes it away without scratching. Avoid sudden temperature changes — hot water on cold glass can crack it.

Ceramic Ashtrays

Ceramic cleans well with soap and water, but unglazed areas can absorb odour. If you notice a lingering smell, soak in baking soda and water for an hour. See our ceramic vs glass ashtray comparison for how they compare over time.

Metal and Tin Ashtrays

Wash quickly and dry immediately and completely, because moisture can cause rust or discolouration. A quick alcohol wipe cuts through oily cigar residue. Never soak metal for long.

Silicone Ashtrays

Silicone tolerates hot soapy water and can even go in the dishwasher on many models. It can hold odours, so a baking soda soak helps. Because it doesn’t break, it’s a good choice for travel.

Removing Sticky Residue and Stains

Tar and resin form a sticky brown film that soap alone doesn’t lift. Wipe it with a cloth or cotton pad soaked in isopropyl alcohol, let it sit for a minute to dissolve the residue, then wipe clean and wash normally. For stains, make a paste of baking soda and water, scrub gently, and rinse.

Getting Rid of Lingering Odour

If an ashtray still smells after washing, soak it in a baking soda and water solution for an hour, or leave a small bag of activated charcoal beside it. More on tackling the smell in the room itself is in our guide on getting rid of smoke smell.

Choosing an Ashtray That’s Easy to Clean

If cleaning is a chore, the ashtray design is probably the problem. Smooth interiors, few crevices, and non-porous materials clean fastest. Our guide to choosing an ashtray covers what to look for, and our best ashtray for home roundup has examples.

Frequently Asked Questions

Can I put an ashtray in the dishwasher?

Silicone and some glass or ceramic models can go in, but check the manufacturer’s instructions. Metal should never go in.

How do I remove burnt-on residue?

Soak the area with isopropyl alcohol on a cloth for a minute, then scrub gently with a brush.

Why does my ashtray still smell after washing?

Odour can linger in pores or scratches. A baking soda soak usually removes it.

How often should I clean my ashtray?

Empty it daily, and give it a proper wash weekly or more often if it sees heavy use.

Final Thoughts

A clean ashtray takes a couple of minutes if you don’t let residue harden. Empty it daily, wash it weekly, and choose a material that suits how much effort you’re willing to spend.
