Re: Painted Bakelite and paint stripper...
H&S can be taken to excess. In the CPC catalogue, the entries for mains leads that are not fitted with a plug are marked in red "Only for use by qualified personell". They don't ask for your qualifications when you order some.

Re: Painted Bakelite and paint stripper...
Carelessness can also be taken to excess. There's nothing to stop anyone bypassing regulations if they so wish. We all see it daily, and most people get away with it most of the time. By doing so they take full and final responsibility for any direct or indirect consequences. The "THEY didn't warn me" argument doesn't apply in those cases, because THEY did, at some considerable length. People like us can appreciate and mitigate (but not remove) risks. Not all can, and they may be your neighbour or workmate.

Re: Painted Bakelite and paint stripper...
Just to be clear, if any of us wanted to, we could disregard the law, and as much DCM stripper as we wish would be on its way to us 'under the radar' with just two mouse clicks, - one for 'Buy Now' the other for Paypal.
But no, however academically qualified we may be it makes no difference as far as the statutory requirements are concerned. Only 'Professionals' are able to purchase and use dichloromethane based products, and only after successfully completing the HSE assessment and receiving a certificate of competence with a unique licence number. The use of dichloromethane based products is restricted regardless of the type of material being removed from an object. A ban was placed on the market of dichloromethane (DCM)-based paint strippers for use by the general public after 6 December 2011 by the European Union on 3 June 2009. It became a Commission Regulation formally amending REACH (Commission Regulation (EU) No. 276/2010). In 2014 the Department for Environment, Food and Rural Affairs (Defra) produced the REACH Enforcement (Amendment) Regulations 2014 (SI 2014/2882). The Regulations amend the REACH Enforcement Regulations 2008 (SI 2008/2852) to allow the supply and professional use in the UK of paint strippers based on the solvent dichloromethane (DCM) by introducing necessary training requirements and a mandatory HSE certificate of competence for professional users. Copies of the Regulations, explanatory memorandum and impact assessment are available at www.legislation.gov.uk. Source: https://www.hse.gov.uk/pubns/wis19.pdf https://icon.org.uk/system/files/doc...thane_faqs.pdf So yes, by all means, anyone who is so inclined, can easily get hold if the stuff, if they are content to break the law. Ride at your own risk.

Re: Painted Bakelite and paint stripper...
Lidl sell baufix or powerfix branded cans of solvent labelled either 'cellulose thinner' or 'paintbrush cleaner-restorer'. I haven't found a paint that is resistant to it yet, and it's also dissolved paint brush handles, screwdrivers and welded a cleaning cloth to the back of my swivel chair. Worth a try!

Re: Painted Bakelite and paint stripper...
Also known as "gunwash" for cleaning spray guns.
Its EXTREMELY active, not to mention flammable. Joe |

Re: Painted Bakelite and paint stripper...
I've had great success using DOT. 3 brake fluid over the years. It's much more effective than Nitromors.

Re: Painted Bakelite and paint stripper...
That reminds me that the old Castrol Girling Crimson brake fluid used to be an excellent paint stripper, but it hasn't been in the shops for decades. I used to use it for stripping oil paints from polystyrene models prior to repainting. None of its replacements had any significant effect. Is DOT3 a commercial vehicle product?

Re: Painted Bakelite and paint stripper...
DOT 3 & DOT 4 are pretty much standard for most vehicles these days and both should work for paint stripping depending on the paint. Care needed though as with any paint stripper. Brake fluid is toxic and particularly damaging to the eyes if they become contaminated.

Re: Painted Bakelite and paint stripper...
Which brings us round to if it works well, it's probably toxic in one way or another, and needs handling and disposing with care.

Removing spray paint from bakelite
Hello Forum,
From the info from this older thread that has been closed, it looks like it's ok to use paint stripper or nail polish remover to remove the paint without melting the bakelite surface, is that correct ? Yes/No Just double checking. Thank you. |

Re: Painted Bakelite and paint stripper...
Bakelite itself isn't damaged by any paint stripper I've ever used, but other plastics found in old radios may be, so care should always be taken.

Re: Painted Bakelite and paint stripper...
I am surprised that no one has suggested trying caustic soda to remove paint from bakelite.
It softens linseed oil and water based 'vinyl' paints. I use it to rescue plastic filament paintbrushes. Don't try it on animal hair/bristles. Some people have warned us about soaking bakelite in water based products because it could swell the wood flour filler in the phenolic binder. I have not tried it on bakelite so I can't comment from experience. |

Re: Painted Bakelite and paint stripper...
OK Silicon, I'll pick up some of that too and give it a try on a not so obvious area.
Cheers. |

Re: Painted Bakelite and paint stripper...
While according to earlier posts supposedly banned, dichloromethane (methylene chloride) is still freely on sale in small (57ml) bottles under the name Plastic Weld, available from shops that sell plastic model kits and on-line (search for E M A plastics). Excellent for mending many types of broken plastic items..
Perhaps the ban only applies to stuff that is intended to be used as a paint stripper. Like a story I heard on the radio some years ago, when the narrator's cat had something wrong with it that required a dose of aspirin. Pharmacists often ask what you need painkillers for, and when he said what it was for, he was informed that it could only be issued for that purpose under prescription. He had to find another pharmacy and say it was for a headache. Likewise, on Gardeners Question Time, it was mentioned that dilute detergent (washing up liquid) is no longer allowed to be used commercially to get rid of Aphids unless you wear complete body protection clothing, because if you get some in your eye it will cause irritation. However, you can use it to simply wash the leaves!. Last edited by emeritus; 7th Feb 2023 at 7:56 pm. Reason: typos |

Re: Painted Bakelite and paint stripper...
You can get larger bottles of 'Plastic Weld' here:
https://modelshop.co.uk/Shop/Adhesiv...-300ml/ITM8946 I read somewhere that while it is legal to sell and use dichloromethane as an adhesive for plastics, it is illegal to use it as a paint stripper (not just to sell if for that use). So presumably if I spill a little while mending some plastic part and it attacks the paint on something on my workbench I've broken the law. As for removing paint from Bakelite, I've had success using a strong solution of biological washing powder in warm water. You have to leave the part soaking for some time but the paint will soften and can be rubbed off. |

Re: Painted Bakelite and paint stripper...
"Mr Muscle" oven cleaner can be used for paint removal on fibreglass boat hulls. I've done this succesfully in the past. Might be another option.
