go open the cabinet where you keep the cleaning stuff and pick up any spray bottle. turn it around. read the first word of the ingredients.
it says water. it says water on nearly every bottle in that aisle, and ingredients are listed in descending order, which means water is not a minor component of what you bought. it is the main one. everything else in there is a rounding error riding along in it.
i own a cleaning company, so i buy this stuff in quantities that make the arithmetic obvious. and the arithmetic is: you are paying a company to put water in a plastic bottle, freight that water across the country, warehouse it, shelve it, and sell it to you a few feet from a tap that would have given you the same water for free.
this is not an argument about which cleaner is better. it is an argument about which form of a cleaner you are buying, and it is the cheapest switch in the house because the chemistry does not change at all.
the dry version is the same product with the water taken out
powders, tablets and concentrates are not a different category of product. they are the same actives, shipped without the solvent, and you add the solvent at the sink. that one change does three things to the cost.
it takes the freight and the packaging out of the price. it takes out the per-bottle plastic, because you reuse one trigger sprayer. and it kills the thing nobody counts, which is that a half-used spray bottle gets bought again before you finish it, because you cannot see what is left.
a fourth one, if you live somewhere with a real winter: a liquid in an unheated garage freezes, separates, and comes back out of it a different product. a powder does not care.
the four dry things i would actually put in the cabinet
Bar Keepers Friend is the clearest example of the whole argument. a powder — oxalic acid plus a fine abrasive — that replaces a shelf of specialty sprays for stainless, porcelain, glass cooktops and the brown film inside a sink. you wet the surface, not the powder. i am recommending the category, not telling you it has lived in my kit for years, because it has not. what i can tell you is that nothing else does that job at that cost per use.
OxiClean Odor Blasters in the big tub is sodium percarbonate, which is a powder that becomes hydrogen peroxide and soda ash the second it hits warm water. the oxygen it is named for is not in the tub. you make it. that is why a tub of powder outlasts a wall of pre-mixed laundry boosters, and it is the right call for boot season, which around here starts about now. category pick.
Affresh washer tablets are a tablet for the same reason: the job is to dissolve into a drum full of water you were going to fill anyway. buying that pre-dissolved would be buying a jug of water to put into a machine full of water. i have not used these specifically; the mechanism is what i am vouching for, not the brand.
and Zep acidic toilet bowl cleaner is the concentrate half of the argument, and this one is mine. it is on the list of things i actually buy for the company. it is a professional acid, it is not diluted down to consumer strength, and you use a fraction of what you would use of a supermarket bowl cleaner to do more. that is what paying for actives instead of water looks like.
where the real money is, which is not products at all
the deeper version of this: the cheapest cleaning product is a tool, because a tool has no water in it and no refill.
microfiber cloths out of the automotive aisle are a thing i genuinely buy, in bulk, and they are cheaper than the ones sold for housework in the cleaning aisle for no reason i have ever been able to identify. a stack of those is the single biggest per-job cost reduction in this entire post, because the cloth is doing work the product gets credit for.
a pumice stone on a handle is another one of mine, and it is the purest example of the principle. the ring in a toilet is mineral scale. you can keep buying bottles to throw at it, or you can abrade it off once with a rock that costs almost nothing and lasts years. the bottles were never going to win that fight; i wrote about which acids actually touch scale and which ones are folklore separately.
the honest exception, because there is one
if i stopped here this would be a tidy post and a slightly dishonest one, because i do buy a ready-to-use spray and i am going to keep buying it.
the multi-surface cleaner i use is pre-mixed water in a bottle and it is on my list anyway. the reason is the thing the concentrate crowd skips: when you use something forty times a day across a dozen houses, the dilution being correct every single time without anybody thinking about it has real value, and so does not stopping to mix. a concentrate you mix wrong is either a waste of product or a streaky surface you now have to do twice.
so the rule is not “never buy water.” it is: buy water when the convenience is genuinely load-bearing, and stop buying it for the nine products where it is not. most cabinets are the other way round.
and this sits next to a thing i have said before, which is that the cheap version is often the one you buy twice. these do not contradict each other. cheap-and-bad is a false economy. the same actives without the water is not cheap, it is just unpackaged.
the safety part, and it is not optional in this post
buying stronger, more concentrated products means the mistakes get bigger too, so this is the price of the advice above.
never put an acid and a bleach in the same bowl, bucket, or session. that Zep is an acid. a lot of the thick clinging toilet gels are bleach-based. acid plus bleach releases chlorine gas, in a small room, with the door shut, usually while somebody is kneeling over it. this is the one real emergency available in a bathroom, and it happens to people who were being thorough rather than careless. pick one. flush between. do not stack products because neither of them worked alone.
do not decant a concentrate into an unlabeled bottle. this is the actual hazard of switching to concentrates and nobody mentions it. a strong unlabeled liquid in a kitchen with kids in it is a poisoning waiting to happen, and “i will remember which one it is” is not a label. write on it. if you have small children, the concentrate does not live under the sink.
and with powders: wet the surface rather than the powder, do not create a cloud of it over a sink you are breathing across, wear nitrile gloves when you are handling an acid at working strength, and rinse properly on anything food touches. that glove listing defaults to size small, which is wrong for most adults; i am recommending the category, not that brand.
the version of this you can do today for nothing
you do not have to replace anything. go read the first ingredient on everything in the cabinet and notice how many are the same first five ingredients in different bottles with different rooms printed on the front. once you have seen it you cannot un-see it, and you stop buying the bathroom one and the kitchen one separately.
if you want the list of what i actually buy for the company, with nothing dressed up, it is here and it is boring. and if your instinct right now is to go replace things, read the one about how half of what you replaced was not worn out first. buying differently is cheaper than buying again.
some of the links in this post are affiliate links, which means i may earn a small commission if you buy through them, at no extra cost to you. four of these are products i actually buy for my cleaning company — the Zep, the multi-surface cleaner, the automotive microfiber and the pumice handle — and i have said so where each one comes up. the rest are flagged in the sentence that links them as category recommendations rather than things i have personally used. #ad #WalmartPartner
