24:22 another thing to try is cutting non-porous rubber and covering the part then pressing it down tight with some plastic blocks and a clamp, and that should seal out the water from getting to the part. That might help for labels that cant be removed. There's also a paste you can make with the peroxide material and manually apply it and it works the same without needing to soak the part, might work for sensitive areas wound decals if you can find a way to protect them from the rest of the solution. Maybe a large suction cup even.
Thank you for the tutorial! I have a few white vintage Mieles and they have yellowed. PS: Thank you for the help with the SEBO e/k 3- I have ordered my E3 premium+boost and it will be arriving tomorrow :) Edit: I didn’t realise you already looked into the lamps, sorry 🙏🏻
I do have a concept one by Hoover as a retro model the American white cord was frayed so Austin vacuums fitted a black Chinese one to cover for it but it still works fine as having a new cord reel
Love it, great video! Out of interest do you know how long it lasts once its been restored before it goes back to yellow again? Ive heard people say it barely lasts a few months before going back to normal
What a great job 👏 I might try this on a front end of my Electrolux 305 . I’ve got a Hoover freedom 1000 that’s gone a bit dark but very nervous of the Hoover logos on that one
All my hoovers were in the attic for two years they all went up white /pale gray I know it was cooking up there in the summers all came down yellow I'm sure they bake in the heat .
Oxy powder is a derivative of sodium percarbonate (green bleach it is eco friendly if you buy it in this form, take a look at Nancy Birtwhistle, she has a few books on natural cleaning products, they really do work, thought they might be of interest to you Roger, as the green bleach may work well on your yellow plastic.
It can work on coloured parts. I used this method to make the front panel of my Hoover Powerdrive (Dialamatic) blue again after it urned a shade of green.
The reason ABS discolours is because there is a fire retardant chemical in the plastic called “bromine” and that reacts with heat and UV of the sun, it is this chemical that discolours, which unfortunately changes the colour of the entire plastic. The hydrogen peroxide combined with UV exposure will react with this chemical and draw out the discolouration on the surface layer of the plastic, however, it can’t correct the damage already there and is susceptible to relapse and discolour again, meaning the process will inevitably have to be repeated, which, will eventually degrade the plastic over time. The only permanent solution is to wet/dry sand to remove the damaged layer OR a lint free cloth and 100% acetone, to remove the damaged layer, with a final mix of acetone and methylated spirits, to bring the shine back. Both of these methods are quite involved but it is permanent, however it is no good for textured ABS plastics or anything with decals, as they will be removed. You did a great job on that, Roger, keep it well air circulated and in a dark place which is relatively cool, if possible, this will help keep your hard work blossoming for as long as possible.
The wet sanding and acetone is a new one to me. Question being how to you bring back the original glossy finish as well as the decals to factory spec, and then seal it?
@@MrWolfSnack You wouldn’t be able to bring back the decals, as removing the top damaged layer completely with either sanding or acetone would take with it the decals and any textures. I am not sure what you mean by sealing. The plastic is either restored to its original shine by different grits of sandpaper. With the acetone method, the methylated spirits mixed with the acetone will restore the finish by reducing the intensity of the acetone, to smooth the plastic back but lint free cloths are imperative. There is a video on how to do the acetone method on a 1970s telephone, on RU-vid. It works well and is really fast!
@@NumaticVacuum I know about the decals, I mean recreating them from scratch. And by sealing I mean sealing the plastic so it has a glossy finish and doesn't get exposed to oxygen and yellow again.
I think these might be before fire retardant it was explained to me that it was something called a plasticiser. it's the same problem that old wires had with the green goo leaking from sockets
@@ConfidentialMeerkat Damn is that what that is? I have a few 80's electronics that have green goop leaking from the cords and I never plugged them in because of that, and I hadn't got around to asking what that was yet.
