I really wish powder detergent worked with the fucking rock hard water we have here, but it creates a godawful crust on everything on the first wash. I just use an enzyme based liquid detergent instead, and it works perfectly well if I otherwise follow the same steps he recommends.

I also have hard water where I live, and I've found that leaving a cup (or two, if it's really bad) right-side up in the top rack and filling them with white vinegar before a wash will completely prevent any mineral buildup from forming in the load, as the acidity in the vinegar allows the minerals to dissolve into the water.

(if your water is only kinda hard, you can try only adding vinegar every second or third load, once you notice the mineral build-up. Even if you're in a really hard-water area, worth experimenting with how much you really need).

I’ll have to give that a try! I use citric acid for cleaning cycles, but vinegar is cheaper.

Acid no bueno for the aluminum basket spindles on all modern washers. Better off sending in softened water.

Citric acid is the primary ingredient in most dishwasher cleaners. Of course, not a good idea to use it in every load. However, my DW manufacture suggests up to 10% citric acid solution as an alternative to rinse aid.

I haven’t seen any aluminum in a dishwasher, and I have noted that if I send any aluminum through it tarnishes like crazy and pits on repeat offenses. I don’t think that hot caustic water is any environment in which to design an aluminum part.

That said, again, dishwasher detergent is basic, so you’re right in that adding acid probably won’t improve the efficacy of the wash cycle.

Though I can't confirm this, I suspect that the vinegar is mostly removed with the the pre-rinse water, which may negate or disrupt an added pre-rinse detergent, but should be mostly gone by the main wash to not effect the main load of detergent released at that time.

The spindle that supports the basket in washers is made of unprotected aluminum and designed to fail at about seven years of use. On Bosch models, they seal this in so it cannot be fixed.

Any sources on that?

[–] Catoblepas@piefed.blahaj.zone 3 points 1 week ago* (last edited 1 week ago) (1 children)

Is there a way to do that with a sink hookup that also allows my sink hookup dishwasher to attach to it? I rent and don’t have access to the water heater, or the OK to mess with the guts of the sink, or open up a wall or anything like that.

Either way it’s not a big deal, worst case scenario I keep doing what’s been working fine.

You could try something like that, then you would have to also pick some fittings to match whatever your dishwasher supply line uses. You would also need another short hose between the filter housing and your dishwasher. I think you could recharge the cartridge by soaking it in salt water occasionally, but otherwise they sell replacement cartridges.

[–] Catoblepas@piefed.blahaj.zone 1 points 1 week ago

Sweet! I dunno if it’ll fit, but I’ll look into it.

Have you tried dishwashing salt?

[–] Albbi@lemmy.ca 2 points 1 week ago (2 children)

I have a dishwasher with a water softener, but have no idea where to buy the salt for it. (and I ain't looking on Amazon)

[–] oasis@piefed.social 2 points 1 week ago

Most grocery stores have it where I live.

Have you varied the dosage? It may take some effort to overcome the chemistry. My DW manufacturer suggests as an alternative to rinse aid using a solution with no more than 10% citric acid, which may be an option.

Another option is to keep an eye out for used European style dishwashers; they often have softeners built in with a salt reservoir in the base. That assumes you can change the dishwasher which you may not be able to.
