Methylene chloride CH2Cl2 is a strange name, after all, 'methylene' doesn't exist! Dichloromethane is logical. And whoever decided to rename carbon tetrachloride CCl4 as tetrachloromethane deserves to be shot - after all, we haven't renamed carbon dioxide CO2 as dioxymethane, have we? Or even oxymethanal or oxyformaldehyde? Which would be just as logical! Traditional Nitromors indeed contains methylene chloride, and also methyl alcohol (dunno the proportions). Both nasty, but they do work well. I haven't had any trouble with 'new' Nitromors, except that it takes ages. I tend to paint the stuff on, and if the paint is old I put the whole lot in a plastic bag, to stop it drying out (which is fatal, you can't shift it then). |

Re: Traditional Paint Stripper.
The new Nitromors is certainly weaker than the old stuff, I have to use twice as much to get the job done and it takes longer.
I don't have a problem with that if it's less harmful, if it's an old radio cabinet being refurbished it isn't anything to rush anyway.

Re: Traditional Paint Stripper.
Homestrip (available from Toolstation) is far and away the best paint stripper I've ever used. I urge you to give it a try. I've shifted all sorts of horrid super thick old paint with it... from 300 years worth of finishes on doors and beams in our house - through the 1970's grey paint on a Lenco turntable - to the paint and underseal on the sills of our Citroen C3.
It's available from Toolstation. https://www.toolstation.com/home-str...remover/p70267 This stuff, like other modern strippers, takes a little while but crikey - be patient! It's not as if restoring an old radio is a speedy job!!!!! Safe to use, kind to the environment and not harmful to your skin. Steve.

End quote. Rats as vermin is one thing, but the rats in question aren't vermin - they're lab rats, bred for the purpose of experimentation, followed by dissection to ascertain the effects of toxicity. I thought things had moved on a bit from that. I'm not lobbying for rabbits and rats - just saying.

Re: Traditional Paint Stripper.
I agree with Dave - I'm not a fan of determining toxicity by killing lab animals. We know DCM and methyl alcohol are hazardous, we don't need to maim any creature, we have the knowledge.
Any replacement, however has to be quantified for toxicity, so by-bye another load of creatures. (I note the LD50 is 800mg/kg and LD dermally is 20,000mg/kg so as an 87kg human, assuming I am physiologically similar to rats, I would need to drink 69g or pour 1.74kg over myself to have a strong chance of being killed). I'm not a rat lover, but I agree with Lewis Carroll when he wrote about animal experimentation - practicing it suppresses natural respect for life and develops a culture of ruthlessness which will be our undoing. If it was a choice of killing a load of rats (and making them increasingly uncomfortable as the 'safer' the chemical, the more you have to make them eat it in order to kill 50% of the sample) to find a safe stripper, or just putting on PPE to use traditional Nitromors, I'd reach for my PPE and the traditional yellow tin! |

Re: Traditional Paint Stripper.
How about keeping animals away from the radio cabinet being restored (a Murphy A104 I believe)?
Saving the planet is a little outside our remit. |

Re: Traditional Paint Stripper.
Good points. I'd like to see the data sheet that you are referring too but I cant find it on the manufacturers website.
I too am not at all happy about animal testing and the LD50 test has failings in my opinion; in addition there's a lot of testing still carried out on everyday household products. However, I guess the tests on Homestrip have been done now and so cannot be undone. I seem to remember that some of our standards for electrical safety are derived from data obtained by lethal experiments carried out by the Nazis on humans. We all use RCDs which have operating characteristics based on that information. I'm not sure how happy I am about that either!! Steve.

I mentioned it because of concerns raised by other, which I respect. The thread is primarily about what paint strippers currently legally on sale for use by non-professionals in a domestic setting, are the most effective.

Re: Traditional Paint Stripper.
I reckon that Wickes' stuff is worth a try! I've taken thick, grotty varnish off transformer bodies with it very nicely.
The issue of toxicity is interesting; until quite recently, 'scientists' had told everyone that humans could tollerate exposure to a certain level of lead without harmful effects. Current thinking is changing to the view that there is no safe level; some lead does some harm, more lead does more harm. Foetal humans are at special risk. It would be no surprise to find out that the same perception gets applied to very many chemicals as time goes by. B

Re: Traditional Paint Stripper.
Our kitchen table top needs stripping - the varnish has gone sticky, it's a nuisance.
What's the concensus here for the best varnish stripper? Thanks chaps...

I wonder if that chap invested in lead lined underwear after that

Re: Traditional Paint Stripper.
It is indeed. The regulations are here to stay, as are the "workarounds" pursued strictly at one's own risk. Unless anyone knows of a product not so far mentioned there is little more to add.
