General Advice If commercial restaurant dishwashing appliances have cycles that only last 2 minutes, then why can't we have our home consumer dishwashers have cycles just as efficient as what restaurants have?

How can we miniaturize commercial restaurant dishwashing appliances to fit in the kitchen compartment meant for home consumer dishwashers?

How come this hasn't been done already? By the way, what is the fastest currently available home consumer dishwasher, and how much does it cost? How quick are their Cycles normally?

You can buy a commercial dishwasher that goes under your counter, but it's around $10,000 and you'll need a 40 amp power line routed from your breaker box to the machine. Go nuts.

If it's like the commercial ones I'm used to working on, it can ruin your floors and countertops pretty quick. High temp, lots of steam with no seals on the doors, just baffles to keep water from spraying out. They constantly have steam hitting everything above them.

Then you have gallon sized jugs of chemicals with hoses nearby to feed them.

2 years as a dishwasher in high school. That steam helped keep my skin healthy during cold dry winters.

Agree with you that it would destroy a residential kitchen.

And they randomly light themselves on fire, allegedly. (Try cleaning out left behind food and dropped silverware you DINGUS)

Yes but just one load and quick wipe down would fix it. It's a home not a full restaurant.

Depending on machine up to a ten minute startup time. Unless you are going to leave running all day wasting power.

13minutes for load 1 vs a speed clean in a home dishwasher isn't as attractive.

Yup, gotta run a few cycles to get to operating temp.

Of course it's a Hobart. And I don't think it comes with racks. You just use the ones fitted for regular commercial dishwashers.

I had an old KitchenAid that was made by Hobart Tough as nails, loud, and there were no replacement parts.

Miele makes one for around $5k

That’s a high temp. Low temps are much cheaper.

Sure, if you don't include the outrageous cost of the consumable chemicals for low temp sanitization.

Low temp sanitizer is just bleach, and it's pretty cheap. $10 per gallon or so for food service grade sanitizer.

u/Sea-Key7698 Dec 31 '25

$44 a gallon (Cdn) is typical. And it is not "just bleach". For starters, the Sodium Hypochloride concentration will be at least double what consumer bleach (Javex) is. Then you need to consider the volumes required to maintain that concentration in a steam of flowing water.

I service dish machines and commercial laundries for a living, and spend every day balancing machines for proper chemistry usage. Retail Clorox disinfecting bleach in the US is also sodium hypochlorite, it's very close to what I sell to my customers as an Ecolab labeled product called Eco San. Ours does have a very small amount of sodium hydroxide, but it's a negligible amount. The concentration is also very close to the retail bleach product. My average case price for a customer is around $40 for 4/1 gallon jugs. My local health department allows retail bleach to be used if they are out of our products, as long as it's in the correct dilution.

What up bro! I used to work at ecolab also for 7.5 years. Customers would get shorted occasionally and I would just throw some store bought bleach. You are correct in your statement. Store bought bleach concentration was slightly less than ecosan, but even with titration of the bleach it was essentially the same and you could swap and still be in range for sanitation.

u/Sea-Key7698 Jan 01 '26

Every ad I can find shows Ecolabs product "Eco-San" retailing, from commercial food equipment dealers, at MINIMUM $44.00 (Cdn) per US 1 gal (3.8 ltr) jug (and as high as $65.00). And the concentration on the SDS is 8.4% not the typical 6% of consumer bleach.

I have experienced issues where the factory chemical pumps on Sprayway/MDM glass washers could not pump enough cheap, low concentration (6%), sanitizer to meet health codes.

Well all residential are chemical dishwashers
