Finish is the better pick for most people: it is cheaper per bottle, easier to find, comes in both liquid and tablet formats, and is built to remove grease and limescale. Glisten is worth choosing if you want a cleaner that is also sold as an EPA-registered disinfectant, and you don’t mind paying more per bottle. Both are monthly-use liquid cleaners that go in the dishwasher and run on the hottest cycle.

Glisten vs Finish Dishwasher Cleaner: Quick Comparison
| Glisten | Finish | |
| Main pitch | Cleans and disinfects; removes limescale, rust, grease | Removes limescale and grease from filters, spray arms, pipes |
| Formats | Liquid (12 fl oz bottle; also a washing machine version) | Liquid (8.45 fl oz bottle) and tablets |
| Disinfecting claim | Yes, EPA-registered as a cleaner and disinfectant | Not the headline claim |
| Typical price | About $16 per 12 fl oz at one retailer | About $4 to $5 per 8.45 fl oz bottle |
| How to use | Bottle in the dishwasher, hottest cycle, no detergent | Bottle upside down in bottom rack, empty hottest cycle |
| Septic-safe | Yes, per its listing | Check the label for your product |
| Availability | More limited; backordered at one retailer | Widely stocked in grocery, big-box and online stores |
Prices and stock vary by retailer and change often, so check the current price before buying.
What this means: the two products do much the same job. Finish wins on price and availability. Glisten wins if disinfecting matters to you.
Cleaning Power: Grease, Limescale and Rust
Both products target the same hidden buildup: grease, hard-water limescale, and food residue on the spray arms, filter, and pipes.
| Problem | Glisten | Finish |
| Grease | Claimed | Claimed |
| Hard-water limescale | Claimed | Claimed |
| Rust stains | Claimed | Not a headline claim |
| Odours | Claimed | Implied through general cleaning |
| Bacteria | Disinfects, per its listing | Not claimed as a disinfectant |
What this means: both are comparable on grease and limescale based on what each brand says. A roundup from FaucetFam notes that a Glisten bottle may need more than one use for stubborn residue, and that Finish’s liquid may not fully clear severe buildup. If your dishwasher is heavily scaled, plan on a second treatment with either one.
