Has anyone used waterless wash with an injection sprayer and extractor?

[SR99]

I was going to try and use UWW+ in an injection sprayer, fed by the 250 psi pump on my extractor. The extractor has a 2000W heater which I can either leave off or turn on, and I wondered if anyone has tried this before.

The thought being, for about the same amount of water+UWW I'd mix up to do a rinseless wash (3 gallons water, 1 oz UWW+) I think I'd be able to blast the whole car and float all the light dust/dirt off, under pressure. Granted 250 psi is nothing like a pressure washer, but it's probably enough to float light dust/dirt off.

My main question is whether UWW+ is heat-sensitive and it's not advisable to heat it (at most I think it would be about 160-180*F).

Anybody?

I can’t be the first person to think about using your extractor for double duty as a waterless/rinseless wash pre-spray, to avoid the “touching” step of a rinseless wash. And if someone tried it, they probably also tried using the heater, since heat improves the cleaning effectiveness of just about anything.

The reason I hesitate to “just do it” is if the heat ruins the lubricity of UWW+, this might all prove to be a big mistake.

I would not put anything but water into an extractor. You have the chance of ruining the pumps.

Hi Evan, the UWW+ wouldn't be going in the extractor, just in the injection sprayer. The injection sprayer has a concentrated mix of UWW+ and has a mixing valve that mixes for example a 4:1 ratio with the heated water under pressure from the extractor.

PS: an injection sprayer is just a 5 quart plastic jug with a metering valve to mix the jug contents (UWW+ in this case) with the solution line (water in this case) under pressure, and goes out a tee jet. It looks something like this:

I'm not a chemist so my comments shouldn't be deemed as so....


I think for what you're trying to do there wouldn't be any drawbacks that would cause harm by heating the water.

While it's possible heating the chemicals could make them perform either better or worse, (who knows?), I don't think heating the chemicals will cause them to harm the paint.

So might as well give it a try....
