Does an oxalic bath damage the decals?

Just use Citric acid! cheaps as chips, works a treat, doesnt damage anything and safe enough to drink

I'm sure someone in another thread used citric acid and it lifted the chrome..
I've never used personally.

Tin foil, water, elbow grease

Don't use tinfoil... oxalic or citric acid will both work fine (citric is safer). It won't affect the stickers or lift your chrome.

'Well it's had it's (citric) bath but the next day the chrome had lifted in places... '

Just copied this from another thread, not saying you guys aren't correct! Assume the risk is low, but seems like there is a risk. Unless soemthing else made the chrome lift..

I think the guy then proceeded to pay circa £500 to have it re-chromed.. so be careful buddy

That’s what i thought!
But it doesn’t touch the decals right?

oldschoolace · « **Reply #9 on:** December 06, 2018, 07:20 PM »

nope it's no more corrosive then regular water to decals

Jon1971 · « **Reply #10 on:** December 06, 2018, 07:42 PM »

I done an old mongoose recently. Decals were fine. No damage and I had the frame submerged for about 24hrs. Oxalic bath.

I think that's bollocks tbh.. how do you know if it loose?

I wouldn't submerge a single frame of mine in any acid! I'd take some aluminium foil and gently rub it with some water. I'd gently understand how to recover it's beauty. I would never, ever submerge my frame in acid!

Just saying..

It's a lazy way of recovering a frame!

oldschoolace · « **Reply #13 on:** December 06, 2018, 10:16 PM »

geees, you try and help people....

OP if you rub your frame with tin foil there are plenty of threads on here pointing you to chromers assuming you have the cashola

Totally agree with clint,never ever had any problems this way

Tin foil,coke/water and elbow grease total waste of time and effort

but if you have time to waste crack on its your frame to restore whichever way you wish

You've found one thread on this forum where the chrome has lifted after a citric/oxalic bath (the chrome obviously had issues in the first place). Dig a little deeper and you could probably find hundreds of threads on here where members have used this method without any issues whatsoever... it is recommended because it has been tried and tested many times.

Btw if you wanna use tin foil to remove rust from a chrome frame you crack on mate but giving duff infomation out to fellow members on here isn't the done thing so do us all a favour and keep your old wives tales to yourself... thanks.

Anybody used a paddling pool to bath a frame in?

One is enough for me. Wouldn't risk it with any of my frames..

Duff information? Just repeating what another member recently said. There is clearly a risk that some members didn't mention at all! That's the duff information mate. Nothing I have said is duff thanks. Find one word.

Fact is citric acid risks lifting your chrome! That's all. It's a fact. Not duff information!

'Old wives tales'?
I think you want to tone it down a bit buddy!!!

Next time you recommend citric acid, make sure you highlight the risk or I will!

It's not a waste of time if it saves the original chrome

It's a bit authoritarian around here?

Back on topic guys

oldschoolace · « **Reply #23 on:** December 07, 2018, 08:54 AM »

TC I usually use a 3 ring 1m paddling pool. it's needs to be distorted slightly to get a frame to fit but that also helps in reducing the volume of fluid needed to cover the frame.
tubs full of water placed in and around the frame will also help reduce the volume needed and therefore the citric acid is needed.

Regarding the lifting mentioned above, the chrome HAS to be already lifting in order for the water to get underneath it!
citric acid will not penetrate secure chrome! There are a ton of thread on here with successful results and I personally have had fabulous results on numerous occasions.

contrary to duff info you may read on the net aluminium foil WILL remove rust BUT the chrome and rust particles becomes lodged in the foil turning it into a harsh abrasive.
it's great on axles, spokes etc but WILL DEFINITELY scratch your chrome.

As with anything, do your research. The Tech and resto pages on this site are some of the best out there and a wealth of information

Citric acid or oxalic acid will only remove rust! if the rust is the only thing holding your bike together it will not magically rechrome you bike for you.

We must also remember that not all chrome is equal. some is laid down over copper then nickle, other stuff is just laid down as cheaply as possible. As with most things prep and the environment is key!

All things to bear in mind when dealing with chrome

This is my how to thread :daumenhoch
