Speak to that guy. He had to rechrome his frame after citric bath apparently..

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.  :daumenhoch:

'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!

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

Tin foil,coke/water and elbow grease total waste of time and effort  :idiot2: but if you have time to waste crack on its your frame to restore whichever way you wish  :daumenhoch:

It's not a waste of time if it saves the original chrome  :idiot2:

It's a bit authoritarian around here?

Back on topic guys

oldschoolace:
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  :daumenhoch:

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  :daumenhoch:


This is my how to thread  :daumenhoch
