Default Cost of Freezer Spray.

I haven't looked at the cost of freezer in a long time, but I was shocked when I saw RS selling a 400mL can for around £20:00.
The non-flammable freezer is more expensive than the flammable type which is typically used for freezing pipes etc.

Plastikote do a non-flammable 500mL can which I've seen for as low as £9.00. This is intended for electronic use. Years ago I do remember some freezer reacting with solder flux and causing it to bubble. The boards did look messy afterwards.

The Ambersil and Servisol brands are all around the same price as RS's own PRO range. Just makes me wonder why the Plastikote is so much cheaper...

SJM.

Isn’t there a cheaper one that’s aimed at removing chewing gum?

Thanks Lloyd, yes I've seen that. In fact Plastikote do their version of that too. I don't to go wafting freezer onto a pcb and leave some nasty residue behind afterwards.

Regards SJM.

Cheap, but this is the inflammable version. So if there is anything hot nearby (like a valve, or other hot part) it could get a little exciting.

But I like the suggestion on that Amazon product that you can use it to free up stuck or rusted screws.

What about those "Air Duster" sprays inverted, they only cost just about a pound a can in the "pound shops".
Just tried one, they are cold enough when used upside down, and no damage to solder on a scrap board.

Have purchased the non-flammable Electronic Motip freezer spray.
Worked out at £6.00 per can when buying 6. Motip are based in the Netherlands, best known as the Plastikote brand in the UK.

Will post again with findings! SJM.

Some years ago the price doubled on Freezer spray due to the previous use of 'greenhouse' gas. The 'newer' gas is less of a problem, just much more expensive.
I recall it was about a fiver a large can which jumped to £9.99 for a smaller can.

Google ‘poop freeze’ (for dogs).
I bought a 150mL can from B&M for £1.99 last year - have not looked recently.

Ditto - not as effective IMHO, and leaves a bit of a residue,but a lot cheaper. I think mine came from Home Bargains.

I haven't tried this, but perhaps a layer of cling film over the suspect component and surrounding area would avoid the need to clean up any residue while still having a good cooling effect? Assuming of course that nothing is getting hot enough to melt cling film.

If you turn a can of air duster upside down, it will act as freeze. I have used that trick quite often.

Another vote for inverted air duster. The dog poop freeze spray works well too but the cans are on the small side. Useful for getting you out of trouble.

Default Hasn't Freezer spray got expensive.

Whilst fixing a tuner I used up my last drop of freezer spray and went online to CPC, Amazon, eBay etc and was seeing prices north of £20 I can't remember ever paying that much before and the last tin probably lasted 10 +years I presume it has had to be reformulated to meet some new rules, does anyone know a more economic option?

Well, your friendly pub landlord holds small cylinders of CO2... but not sure how you go from there.

You can get big cans of the stuff at a relatively-bargain price from anywhere that does plumbing supplies to the trade, where it is sold as 'pipe freezer'.

Poundland used to sell small aerosols - not sure if they still do.

I bought some Kalte freezer spray from "60 oldjohn" of this forum last year. It may be worth contacting him to see if he has any left for sale. It's been very good when I have used it, leaving no residue.

I have used an “air duster” from Poundland quite recently. It is quite cheap at £1-2 a can and the evaporation of the propellant makes a surface go cold. Possibly not to the extent of freezer spray but probably good enough to cool components down. I believe it is also non flammable.
