John L Posted July 9, 2021 Report Share Posted July 9, 2021 A general question that would help me and others perhaps? What freeing agents do must of us use, and perhaps more importantly where can they be bought. Are there one or two that stand out above the rest. I know WD is readily available, but not sure that its for the real stubborn rusty items, but does sort of work sometimes. I know of Plus Gas from long ago, but have not seen it at parts counters, where's the best place to purchase. I've heard also of freezing products but not knowing, are some better than others, precautions with use also perhaps. John Quote Link to post Share on other sites
Richard71 Posted July 9, 2021 Report Share Posted July 9, 2021 Hi Join, In my experience WD40 is pretty close to useless as a freeing agent, Plus Gas is great, available from Euro Car Parts & Halfords, equally good (if not better) and cheap as chips is diesel, brush it on, soak it or whatever, works a treat!

RobH Posted July 9, 2021 Report Share Posted July 9, 2021 Screwfix sell Plus Gas John. There's also Shock & Unlock from Halfords ( they don't seem to have Plus Gas any more). +1 for diesel - works well if you leave it to soak for a while. Quote Link to post Share on other sites

Richard. +1 for both assessments. I've found WD40 is really good for cleaning my engine compartment. In days of old it was great for dispelling water on traditional mini ignition leads. But for freeing Plusgas is excellent, in a totally different league. Quote Link to post Share on other sites

BlueTR3A-5EKT Posted July 9, 2021 Report Share Posted July 9, 2021 I am still working through the box of Moovit I was given 35 years ago. I have still a couple of cans left. Damn good stuff, certainly in the plus-gas league. https://prairiebearingshop.com/moovit-penetrating-fluid-350g-aerosol-11014/ I have found WD 40 to be of little or no use for seized bolts etc. As suggested above ..... Never tried but am assured acetone and atf does the business. Quote Link to post Share on other sites

John L Posted July 10, 2021 Author Report Share Posted July 10, 2021 Thank you everybody for the info on the liquids, I do have plenty of ATF left over so will make some of that mix up. Does anybody have the info on the freezing products which is best to use? John Quote Link to post Share on other sites
BlueTR3A-5EKT Posted July 10, 2021 Report Share Posted July 10, 2021 Freezing spray. I’ve used this stuff with some success https://www.wickes.co.uk/Wickes-Pipe-Freezing-Spray---240g/p/424922 Still not as good as the ‘hot spanner’ oxy-propane.torch Quote Link to post Share on other sites

John L Posted August 18, 2021 Author Report Share Posted August 18, 2021 (edited) I have tried without success to find PlusGas, from Halfords or Screw fix, but did find it in person at Classic Oils in Bicester, http://penriteclassicoils.co.uk/ but didnt find it on their site, may be worth a phone call if somebody is looking for this product specifically.

ed_h Posted August 18, 2021 Report Share Posted August 18, 2021 Ive used quite a few of these, including the ATF mix, and don't really see a standout. In fact, looking at the half dozen or so YouTube "shootouts", aimed at answering the question once and for all, they all seem to come to different conclusions. I use whatever is handiest. Sometimes It works, sometimes it doesn't. Ed Quote Link to post Share on other sites
Steves_TR6 Posted August 19, 2021 Report Share Posted August 19, 2021 Plus Gas for small stuff Diesel for big stuff for Lockdown i bought a derelict Honda CB550 from 1974 that had been standing for more than 20 years and had a siezed engine. my first action was to put a little Diesel in each cylinder and after 3 days the motor freed up beautifully steve Quote Link to post Share on other sites
John Morrison Posted August 19, 2021 Report Share Posted August 19, 2021 moving on from the original question, what is the best parts washing fluid, Is it still parafin, find the organic stuff now available from machine Mart pretty U/S. John Quote Link to post Share on other sites
HSM Posted August 19, 2021 Report Share Posted August 19, 2021 Just as a point of interest the WD in WD40 stands for water dispersant. Harvey Quote Link to post Share on other sites
ianc Posted August 19, 2021 Report Share Posted August 19, 2021 John, it depends just how clean one wants to get the parts. Petrol works well, but is nasty stuff to use and one has to be careful not to cause a spark! Paraffin is works well, but leaves a slight film, which can be helpful (reduces risk of immediate rusting), or a nuisance because further washing may be required to achieve complete cleansing. Gunk removes most of the really disgusting muck, and is very useful in truly filthy situations, but leaves a coating. One has to consider carefully what is going to happen to the fluid and dirt being hosed off. Ian Cornish Quote Link to post Share on other sites
RogerH Posted August 19, 2021 Report Share Posted August 19, 2021 Hi John, for de-greasing I use Wynnes brake & Clutch cleaner in the aerosol can. You can get it as cheap as £2.50 a can (box of 12) or £7+ Halfords. You can get it cheaper if you get a 5Ltr can It is an excellent de-greaser and leaves no residue.

Lebro Posted August 19, 2021 Report Share Posted August 19, 2021 I use "Hyperclean" It works well at de-greasing, & can hosed of with water. I use in my parts washer, & for bigger items in my air powered "parafin" spray gun. Bob. Quote Link to post Share on other sites
