it's called varsol I believe
That would be my assumption. No fire or environmental concerns if water is used over solvents.Wonder if it's just a way for companies to get away with no liability?
Why do all the latest parts washers ( mainly low cost benchtop and 20 gal) say use only water based fluids? I need something in my garage but don't heat 24/7 in winter. Anyone use solvent/ kerosene in parts washer marked for only soap? Wonder if it's just a way for companies to get away with no liability? or will it fail the pump?
Back in the late 80s I worked at a water ski company making skis and we would use MEK to clean up resin regularly. Very nasty stuff. Somtimes a respirator but usually not. Gloves always. Young and dumb. When I worked at Boeing you needed a special ID card to get/use MEK. A few years back I did see it in quart cans at Lowes.MEK is bad stuff, attacks the liver, got a senior supervisor terminated over having a summer help, usually employee's
kids wash some fans with a big pan of MEK, no PPE at all, just a bath towel, I was a maintenance man on that floor
when I seen that. Stopped him, his dad was a maintenance man i worked with I callled him to get some clean clothes.
Sent him to the shower and went to the Plant Supervisor armed with the MSDS sheet. We had a very heated meeting and
he left unemployed, he was a bully to these young people giving them all the dirty jobs he could, it did help that I was on the safety
team, you teach these young people how to do things right and safe, not bulley them.
The pump in a 30 year old HF parts washer was made to be used with solvents. Try that with one made in the last ten years.I don't know what kind of pumps you all are using, but the pump in my HF cleaning tank has been running solvent thru it for more than 30 years, still works just fine.
Remove the front o-ring from the pump inlet and it works just fine; stated above in post #44.The pump in a 30 year old HF parts washer was made to be used with solvents. Try that with one made in the last ten years.
comparing the two SDS they are close.
That's my point. Solvent 142-66 isn't the one and only option.comparing the two SDS they are close.
The point was the guy with the 30 year old HF washer doesn't have the same thing as what's currently available. I'm aware that you can modify anything to make it work.Remove the front o-ring from the pump inlet and it works just fine; stated above in post #44.

I inquired about this, but they told me they require a business license to service my shop. This is a side gig, so I ended up with the PSC1000. But I would like to know more about using kerosene.Safety Kleen will sell you solvent and will also come out and swap it out when its dirty for a fairly reasonable price.
I haven't used Safety Kleen since the 90's, last time I was in a shop that had it. It worked fantastic. Now I have my own shop and I use PSC100, and it doesn't clean nearly as good as I remember the SK.Crown PSC 1000 appears to be basically the same. If you have a Tractor Supply near you, it's $90 for 10 gallons.
And no worries about the lower flashpoint? I am not a flashpoint expert, but.......I've been using kerosene in my 30-yr old HF parts cleaner with no problem. I clean it every now and again and buy kerosene by the gallon at a service station. It's not as cheap as it used to be but works pretty well.
Ok. That awareness was not conveyed by your post. Either way, it's a potentially 60-second procedure to "modify" the new parts washer to operate perfectly with solvents.The point was the guy with the 30 year old HF washer doesn't have the same thing as what's currently available. I'm aware that you can modify anything to make it work.
It would be interesting to see a direct side-by-side comparison of today's Safety-Kleen Premium Solvent vs Crown PSC1000.I haven't used Safety Kleen since the 90's, last time I was in a shop that had it. It worked fantastic. Now I have my own shop and I use PSC100, and it doesn't clean nearly as good as I remember the SK.
That awareness wasn't relevant to the person I was responding to. The quoted post matters.Ok. That awareness was not conveyed by your post.
