Well, It was all going so well and was very nearly finished, but buggered it all up at the end 
. So get a cup of tea and have a sitdown and read on
I got this shuttle from on here with the veiw of giving this hydrogen peroxide method a go. I used it once before on a yellowed shuttle wing outside in the sun and had good results.. Here is the ship:
I already had the center wing off and the other parts. Then got my bucket, which was bought from a garden centre and put the three wings and side hatch and canopy in the bucket
Then ordered some 35% hydrogen peroxide.
I put the whole n5 liters of peroxide in, then added 10 litres of water, then three scoops of oxy powder. I did this in the evening, so there was no uv sun light. I woke up the next day and checked, but nothing had changed :?
I then checked back in the evening and had some pretty good results. There wasnt much uv light coming in the room, but the parts had definatly become whiter and the yellowing has turned very faint. You can see the difference in the wing where it was submerged and where the tip wasnt
This was during the first 24 - 48 hours with the 35% peroxide, oxy powder and water in the 2:1 ratio.
I then left it for another five days, but sawa no further change. I tipped the center wing upside down and tried to de yellow the tip, but nothing further happened. I had read somewhere that the mixture only lasts a few days, but I wasnt completly shure.
I did some more reading up and someone had posted up a thread on another forum about using 12% hydrogen peroxide in the form of a hair product that can be brushed on neat and left on the window sill to get the full uv light needed.
I had another shuttle with some yellowing only on one wing and at the very top of the centre wing so I thought I would try that also:
I also had the body part of the other shuttle, which had a very yellow nose:
I wont tell you what the stuff reminds me of
I checked this after a day by the window and there are definatly some great improvements and at least you can brush the stuff on so a lot less effort and its only £7 also where as the 5 litre 35% is £20 a go.
So up to now I was feeling quite happy with my experiment. I know that it has been reported by some plastics museum that hydrogen peroxide can damage the plastics structure and no one knew the long term effects of this. If I hadn't of used the stuff before to good effect, then I wouldn't be messing around with it now and the stuff is shipped in a plastic bottle, so dispite the huge corrosive warnings on the bottle I decided to push on
So the parts in the bucket had been sat in the mix for six days all up with no further progress. So rather than be sensible and pour the whole mix away and start again. I tipped only half away and topped the mixture up with another fresh 35% 5 litres and added some fresh oxy powder.
I did this in the evening around 5 oclock and checked it regularly before going to bed and there was no change. I fiqured this was because I had done it in the evening with no UV light and was expecting it to work throughout the course of the following day.
Woke up this morning after doing the new mix last night and go to cheack out the progress expecting to find good results and I go in the room to find the peroxide mix all over the floor and the remains of a load of shuttle parts melted and twisted in the bottom of the bucket
I had to mop up all the mixture and luckly I had taken up all the rugs as otherwise I could have buggered up a whole lounge full of rugs and furniture.
I tipped out everything in to the bath being carefull not to get any on my clothes and this is whats left of my hairbrained experiment:
What a bummer. Its got rid of the yellowing though, youll have to admit. It didnt effect the guns which must be due to being made of a different plastic and I cant find a hole in the bucket anywhere, so it must have bubbled over during the night perhaps. I will check it again later to see if the peroxide has damaged that also.
The other part of the shuttle is still on the windowsill with the 12% peroxide on as is the other complete shutle with the one yellowed wing and tip of the centre wing so I will update that this evening with some pics.
I guess I was trying to find out if it is worth buying yellowed stuff to try and restore, but It really isnt worth the effort and time. Each 5 litre 35% peroxide bottle is £20 and I used two. If the 12% stuff works, then it might be worth doing on something you already own and at £7 for a 120ml bottle its quite cheap and ii I find it has worked later on, then it will be quick as well.
Please be gentle with your comments and I hope I havent upset anyone with this thread. I think with the shuttle being so large, it has meant I have had to use the mixture twice, which has meant the experiment was not cost effective So I wouldnt advice buying yellowed stuf with a veiw to restoring it. You might as well pay more for an example which hasnt yellowed in the first place
If anyone has any wings, or a canopy and side door, please let me know as I would still like to save this shuttle and rebuild it. Ill take pars in any condition.
Lets have your thoughts and suggestions on what to do with the remains of the toy.
Thanks for looking and you have been warned
