Whitening yellowed toys with Hydrogen Peroxide

[sideswipes brother]

Just a quick question. Does the stuff eventually 'run out'? After about 4 days of using it i have noticed less and less bubbles on the plastic parts. Is this normal?

Yes it does indeed run out eventually. The better sealed your jar is the longer it will last. Even if you have a pretty good seal on the jar, it will still allow vapors to scape so the 'working time' of the H2O2 depends on how well sealed your jar is.

*shameless plug* I got some summarised tips and results here if you want to have a look (but nothing you wouldn't be able to find in this thread).

Well I have had some success with this miracle cream. Works fairly well on Slugslinger without any real damage to the plastic. I left them out in the sun for 3 hours, cleaned them off and reapplied for another 1 and half hours. Sunlight started to fade.

What you can maybe see in the last picture is there is some streaking on the plastic, which could be from not applying the cream evenly. I used a brush. I am going to test using a sponge to try apply evenly onto another piece to test.

The purple on the sticker was affected, but strangely not the rest of it.

I think the grey plastic worked better because I caked on the cream more thickly than on the blue bit. All things I will look into more detail tomorrow.

One other fun fact that we could use this cream for is rusted screws/metal. The screw in the foot seemed to clear up using it. Pity I didn't take photos of that before I did it. Another thing to test tomorrow.

So testing for tomorrow will be:

- more on the foot to see if I can make it lighter still, it was pretty bad to begin with
- test another blue piece
- put some on a rusted screw to see those effects better
- use a sponge to apply cream and more thicker
- earlier to get a better start on testing for more light

Good to see it worked great ok 1AZRAEL1

I tested the Creme Peroxide on another '87 Transformer, Rippersnapper. I didn't take any photos but he came up great. No issues at all.

I use a thick decent paintbrush and coat it on nice and evenly. No issues with applying it on his stickers either.

Up for test next is '90's "reissue" Classics First Aid.

I did an aerialbot Slingshot nosecone and two of my three original Transformers toys - Fireflight and Blades - today and they came up great with no problems.

I was careful around the stickers but noticed when I was wiping the creme off the red came off the Autobot symbols on Fireflight's wings. These are the original stickers so it may well just have been age. I didn't notice any appreciable change to the other stickers (altho they are 20+ years old and a bit tatty to begin with).

Stickers are a funny thing. Best avoid getting any on them I'd say.

A thicker application worked better. No streaks on the blue parts at all. It is still a deeper blue when compared to a non yellowed part, but it looks much better than a greeney blue. I will put more on it next weekend to see if I can lighten it further.

The grey foot is getting lighter still, and is near bringing it back to it's original colour. Again, more coating next weekend.

The screw is still rusted, but it did remove some of the rusting.

But great news is the fact it is not destroying the plastic like H2O2 does. Hardest part will be trying to do it evenly when you have to do more than one coat. But the great thing is it takes a few hours, so you can wipe it off and check it every so often, and reapply the cream.

Hey dude, just out of curiosity; Do you think that if you were to put the solution into a spray bottle that that would give you a more even coat than using a paint brush?
