Ultrasonic cleaner recommendations

Just my personal opinion, but no acid of whatever type belongs anywhere near scuba equipment.

From the Biox date sheet: pH 2.2
Vinegar has a ph of 2.9 which makes it less acidic than Biox

Just my personal opinion, but no acid of whatever type belongs anywhere near scuba equipment.

The only liquid I use that contains anything that could be called acidic, is a weak citrus based degreaser.

Why so? If you mix "vinegar" and water properly and set the timer for an appropriate time, what is the harm here?

No I didn't, I said it was my opinion, I don't use acid based products, I use Biox, it ain't cheap but it does a very very good job.

From the Biox data page:

Colour - clear
Density - 1.02 SG
Odour - very slight organic odour
pH - 2.2
Boiling point - 96 C.

That just happens to be the ph of lemon juice. Straight vinegar is less acidic and we are talking about a 50/50 vinegar/water mix.

I liked the part in the MSDS about the toxic fumes if burned, and "low VOC". It's got an "ol" or an "ene" in it for sure.
But nice marketing to the environmental crowd. Just no significant difference from the secret "Lawrence Factor Wash", I'm guessing.

There's a limit to what you can do if you're not degreasing with carbon tetrachloride.
A detergent, a surfactant and an acid. They're all variations on that theme, right @couv ?

Yes, Lawrence Factor Wash, Global, Tumble Juice, etc (correct me if I'm wrong) all have as the active ingredient phosphoric acid. The concentration is sometimes hard to figure, but for an example let's look at LFW with a specific gravity of 1.14 (from their MSDS). Compare with phosphoric acid at 85% has a SG of ~ 1.7 / 50% ~ 1.34 / 25% ~ 1.15 so LFW must be ~ 24% phosphoric acid as delivered.

I'm terrible at math and chemistry, so I welcome any corrections. The above is an interpolation made from MSDS and this chart:

But, but, but... that's just Coca-Cola!

 

[Couv]

Phosphoric acid is what puts the TANG! in Coca-Cola, and the reason Coke is a fairly good solvent to use on corrosion.

(You wanna go off on a tangent?) I don't do coke often, but when I do I like Coke from Mexico.

Judgemental much?

Its getting like FB, can't have an opinion without someone jumping on the bandwagon and slagging you off for it.
In future I'll just keep my opinions to myself

Sir this is the internet.... fact checking and slinging mud is what happens here (not to mention the intimate details of the differences between vinegar, coke, and uh, ...sniff sniff...coke)

Relax, share your opinion, just keep an open mind. We've all been wrong before

Well, if that is directed at me, apologies if I did not use diplomacy. However, the intent was to point out that if one wants to avoid acid to cleaners, then Biox is not a good choice. There are alkaline cleaners available that may suit that need.

Here is a link to one such product.
