Cleaning Leather In Preparation For Dyeing

[R Petersen]

Hello all. This is my first time posting here, though I have been following for a while. I have a few questions which I hope you can help me with.

I am quite concerned with the use of acetone, which I have read must be used for cleaning leather before dying. This is because I use my living room as workroom, so the furniture and air would/could both be affected. I'm not sure how much, but I have read that acetone is a quite noxious chemical, so I don't want to take any risk. What I wonder is, are there any other chemicals/cleaners which could be used instead of acetone? Even if it isn't be as good at cleaning as acetone, I'd still be interested, as I am still very much at the practicing phase. Secondly, my father has a large workroom, where I could use acetone without any worries, but it's rare that I visit him. I'm thinking that I could bring cut leather pieces to him and clean there, then do edges, tooling, stitching, dying etc. afterward. Would the acetone affect the ability of the leather to take the later treatments? Or would the effect be canceled anyway during my handling of the leather, as it'd probably get more or less dirty?

English is not my native language, so there may be some creative grammar in my posts.

I have never used acetone on vegetable tanned leather. In extreme cases, maybe lemon juice or oxalic acid, but in the normal course of work, there is no special preparation needed before the finish work begins. Just follow regular routines like not carving on newsprint, keep your hands clean and so on. Acetone would dry out the leather, and you are right, the fumes would be awful. (I have a 12 yr old who loves to paint her nails!)

I agree with Johanna, just keep your work area clean, wash your hands before doing any work.Oxalic acid( also called wood bleach,is available in most home improvement stores) works very well in removing stains,dirt,etc. and is not near as toxic or smelly as acetone.Alcohol is also a good prep, but is only good on some cleaning.Dave

Thank you both. That is very good to hear . I really don't like using dangerous chemicals, but both my leather books mention acetone, so I assumed that it must be used.

Never saw anything about acetone being used as a prep for dying/finishing. I use lemon juice, I take concentrated lemonjuice (grocery store) and mix it 1:1 with water, works great for me.

DON'T USE ACETONE!!! IT IS DANGEROUS UNLESS YOU ARE TRAINED IN IT'S USE. IT WILL RUIN LEATHER!!!

If you have purchased natural, vegetable tanned leather and are looking to prep it for even dyeing, try either oxalic acid or a 3% borax/water solution. I am sure that there are other members on this board that can help you further.

When leather has already been finished with a full pigment coat, sometimes ethyl acetate would be used to strip the finish, but not for prepping.

Please BE CAREFUL

Well I agree with everybody else. I've never heard of using acetone on leather either. I always clean my leather with oxalic acid before dying and antiqueing. I just think it helps keep my antique finish nice and even.

I agree with everyone else here on the use of oxalic acid to clean leather, works wonders in removing the unseen fingerprints and marks left by metal contact with wet leather. I have a heads up though, don't put it in a spray bottle to apply unless you have good ventilation, it will combine with the moisture in your lungs and nasal passages and irritate them. Always use the least amount of any chemical that gets the job done, and read the MSDS if you are unfamiliar with the chemical. Your liver, lungs and skin will thank you.

What kind of consistency is your acid solution?

I'm worried about wetting the leather too much on the surface and diminishing the detail of the tooling.

Any ideas?

Thanks.
