Evening all,
I know this has been covered numerous times but i want to check what lye is and how i should mix it. Is it caustic soda? This is an extract of some instructions i was given -
Removing anodising is really easy. You need only about 10-15% lye solution. Here in Finland you can buy suitable lye solution from the grocery. This solution is normally used to clear slow running sinks. Then put the part which you want to strip to solution and it helps little bit if you brush item little bit. There forms some hydrogen gas so this is best to do in well ventilated area. Lye is also very caustic so good rubber gloves are needed. Stripping doesn't take long time, if you leave aluminium part in the lye for too long time it will will dissolve totally in it. So keep the part only for example in 20 secons or so at first and take it out and wash in fresh water. It is quite easy to see when anodisation is stripped off. When anodisation is stripped it is vey much easier to sand scratches off and polish item.
I wish i had a better memory, i know the alternative is oven cleaner - again do i use it all in a bag or just some?
Thanks all, hope you are enjoying the good weather (even i was out on the bike today!!),
