When I took it out I was saddened to see that where the pillars the screws going into inside the top half were showing white circles on the outside of the case. So whereever the screws go into the top half there were light circles showing the size of the pillar inside...Bloody weird and very annoying. So I did the bottom half and took much more care (ie didn't forget about it) and it came out ok but the top and bottom don't exactly match (top is lighter), its minor but you can see it close up.. I'm still going to do my USA Snes as its can't look any worse and fingers crossed it will be fine.. I'm just catching up on your progress Paul as I've not been online for a few days with this heatwave. Sorry to hear that you had a mishap with the liquid, how long did you leave the case top in? I've been in two minds about whether to risk my breadbin case so I'm certainly put off now, I'm not sure that mine is discoloured at all as the beige is the same inside and out. There's too many variants of the case to judge the shade of the plastic from memory although I do remember my one from the mid eighties being pretty much the same colour. I'm not too worried about the Amiga cases and the light XL case sections, as I feel they will fair well in the liquid. The lower quality XE cases are another concern though.

Mclaneinc Posted August 13, 2020 Share Posted August 13, 2020 (edited) Hi Tezz, my top lid was 18hrs, as said I forgot about it..Well I checked it initially and then lost track of time... The bottom was fine and certainly looks more right than the dark brown its had become.. My next test in the USA SNES the bottom is completely the wrong colour, it should be a bluey grey but its beige, looking online it seems to be a common issue..It looks wrong so I can't possibly make it worse (hopefully) and its a test to see if I continue with the treatment on other cases.. I'm pretty sure it was just my silly mistake on the C64 top..From all the reading its the most safe way to avoid streaking etc..Just keep a regular eye on it Also my tub got pretty warm which I know accelerates the retrobrighting, wasn't too hot but warm enough..

I even managed to keep the stickers on the underside of the cases intact. Though the aluminium model badges could do with some love. That bodge was done before I got the system (which I'm guessing was 1988?), so I assume it's factory or my uncles attempt to improve the display output as it's attached to the RF modulator. I'm sure more knowledgeable people on here can let us know. I've a bunch of parts coming from from the UK and Poland to upgrade the internals and finish it off. Really sorry to hear about that mishap! 1 Quote Link to comment Share on other sites More sharing options...

flemingt Posted August 13, 2020 Share Posted August 13, 2020 yes, U1MB ordered, along with a proper AV cable. Also, some cheap and cheerful ram chips from ebay to get it up to 64kb too. I will try, a lot to learn (and re-learn!). hopefully you have better luck on your next retro-brightening attempt. 1 Quote Link to comment Share on other sites More sharing options...

I retrobrighted a Commodore 1702 monitor, and it showed some irregularities until I wiped the whole case liberally with baby oil. The lanolin in the baby oil might really help your top (and bottom) case. It's cheap and easy; give it a try - I think you'll be pleased.

flashjazzcat Posted February 15, 2021 Share Posted February 15, 2021 Most badly discoloured 1200XL I've yet seen: 9 1 Quote Link to comment Share on other sites More sharing options...
damanloox Posted May 18, 2021 Share Posted May 18, 2021 For me - peroxide in clear liquid form (diluted with water if it's really "strong") and UV light. Submerge the case in the solution, add 2x50W UV lights and 2 hours later the yellowing is gone. If it's really bad - 3-4 hours later. If it's _really_ bad (see fjc's "Italian 1200XL ;)) - spray paint (never did that but @flashjazzcat got excellent results with the 1200XL). I don't like peroxide in cream form - I'm a bit afraid of "streaking" etc... clear liquid works for me. Quote Link to comment Share on other sites More sharing options...

I use "transparent" container which I then wrap (on the outside) with aluminium foil (in hope that some of the UV light will be reflected onto hard to reach parts). Not sure if it really helps but it seems to work for me. Quote Link to comment Share on other sites More sharing options...

Not sure if it really helps but it seems to work for me. Internally reflective surfaces really help, I think. My 'magic light box' wasn't very effective until I lined the inside with aluminium foil. With the foil, it's arguably as effective as sunlight. Quote Link to comment Share on other sites More sharing options...
damanloox Posted May 18, 2021 Share Posted May 18, 2021 I wasn't sure if the aluminium foil reacts with peroxide so I thought outside was "safer" (taking risk at my age is.. risky ;)) Quote Link to comment Share on other sites More sharing options...

I was applying it to the inside of a cardboard box. Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted May 18, 2021 Share Posted May 18, 2021 If you use foil inside the container with the peroxide liquid its spoils the foil..Well it did when I tried it, could have just been that it was really cheap foil..Ideal would be a fish tank with real mirrors on all sides.. I've tried both liquid and the cream methods, neither worked great for me, the liquid did work better with more heat applied.. Must try it again sometime, I've got an Amiga 500 that is just begging to be the right colour again.. @damanloox which country did you do the sunlight way, must have been Poland as Ireland is usually the land of the grey skies and moisture...

damanloox Posted May 18, 2021 Share Posted May 18, 2021 (edited) @Mclaneinc I'm using 50 W UV lights as substitute for the Sun As for ideal container - yes - fish tank with mirrors on the sides would be ideal. But I don't have one and plastic container with tin foil worked very well for me (on several occasions - including XLs, XEs, STs and SNES).

Sugarland Posted June 17, 2021 Share Posted June 17, 2021 Light brightening party! The fan keeps them much cooler. The dark keyboards get hot otherwise. Humidity is about %19 which is probably great for brightening. 1 Quote Link to comment Share on other sites More sharing options...

Sugarland Posted August 1, 2021 Share Posted August 1, 2021 A word of warning about leaving 65XE's and 130XE's out in the sun. It seems the sun is bleaching the color out of the entire badge, including the grey, but most noticeably the red ATARI is now faded. Maybe it's just age and not the sun but not willing to test this theory on another machine. Covering the badge may be advised to avoid this! Two machines shown, XE on right has never been out in the sun or retro brighted. 2 Quote Link to comment Share on other sites More sharing options...
