So this is not pertaining to pressure washing exactly, but rather to the chemicals we use. I have an RO countertop water filtration system that has a fill tank and clean water tank. The fill tank for the tap water over the last 3 years has become crusted with scale from the hard water sitting in the bottom of it (It leaves the nasty water in the bottom 1/3 and you dump it out before filling again). Is there a product we use in this industry that I could soak it in to dissolve the mineral deposits that have seemingly fused to the plastic? Ive tried scrubbing and nothing seems to touch it. Thanks for your input on a somewhat irrelevant post.
Maybe CLR?

Have you used vinegar? I run vinegar thru my coffe pots and my whole house filter every couple months to break up any deposits.

Both great ideas thank you. I forgot all about clr and I have vinegar. I just filled it up with it will see how it works. I’ve always been skeptical of vinegar thinking that it was not really effective but I’ve never actually tried it. This will be a great test!
I have a bunn coffee pot and they actually state it’s the best way to clean it. So I do about half a cup to a pot and run it 2-3 times then flush with about 5 regular cycles of water. Do it to my keurig also. Cleans a lot of buildup out.

I do use it for my coffee machine too but never for anything like this. It’s already working! I saw some 30% vinegar the other day wonder what that would be used for…

If vinegar doesn’t work maybe try and step up to citric acid. Vinegar is one of the weaker acids. Citric is stronger than Vinegar but weaker than Oxalic. There are others in between though.

I just did that to a Keurig coffee maker, didn’t rinse it enough and had the absolutely worst tasting coffee the next morning

Ha yes I do two full pots of water for rinsing. You can still smell vinegar on the first one. So it worked! All that crust is gone! Thanks again everyone.

Glad to hear that helped. It’s amazing what some vinegar will clean. I even use it to clean shower heads, just let em soak.
