Removing Spray-on Dye?

[Sunflower49]

BDAZ-- zowie!  :O)    thanks for the alert on Feibings Deglaze, especially considering I have a large area to try to affect change on!  I'm anxious to get started on the worst parts where the drips are and on the arms, where the leather was damaged, not reconditioned, and now won't take conditioners.  

Again, thanks -- and thanks to everyone who has contributed -- I can now think of this as an adventure instead of a doomed quest.

Not knowing what they used once cant be 100% sure the Alcohol will work but start in an inconspicuous area with a small amount and let it dwell for a bit then see what happens with a paper towel. You will need a lot of paper towels, patience and elbow grease if denatured is the right solvent.

Keep us posted!

BDAS - Fiebing's deglazer is certainly not "mostly ethyl alcohol" as it makes up less than 9%. Ethyl Acetate, which makes up more than 50% of deglazer,  is a much different solvent regardless of how it is made. You must be thinking of Fiebing's dye reducer, which is ethyl alcohol plus a small percentage of  isopropanol. Deglazer costs $20 in quarts. You wouldn't buy 4 oz. bottles to do a chair. While it is true that denatured alcohol is cheaper, it won't effectively strip a finish, even after hours of scrubbing. (It didn't touch the finish on my shoes.) Sunflower49 might want to try a 4 oz. bottle of deglazer and compare it to denatured alcohol. Denatured alcohol is always handy around the house (reducing dye, and all kinds of cleaning chores), so even if it doesn't work on the chair, it won't go to waste.

I was using an older MSDS. A more modern one is Ethyl Acetate 70 - 90%  Ethyl Alcohol 10 - 30% My guess is it's the 70/30 ratio since ethyl is cheaper. However Methyl Alcohol in Kleen Strip is a more active solvent than Ethyl and also contains Ethyl Acetate.

In the solvent industry (I hold patents in biodegradable solvents) we say, like dissolves like, so a lot of the efficacy of either solvent is going to be based on the formula of the offending paint.  In addition, Tandy doesn't sell deglazer in quarts so not sure where you buy yours? I don't use it so I don't source it in production quantities.

There are also a number of less expensive solvents available at the local hardware store including xylene, tuelene and MEK, all nasty stuff to be handled with care, but may prevail when the alcohols dont. 

One problem is that we don't know if this is a paint, pigment or dye that needs to be removed. Your suggestion of trying the deglazer if the denatured alcohol fails is a good one as would be to purchase small quantities of the other solvents mentioned for testing.

I know I am being pedantic, but there is no ethyl acetate in Klean Strip Denatured Alcohol. A 2014 SDS showed that there was <2% ethyl acetate, but as of 2015, there is none. It is now approx. 50/50 ethanol and methanol.

The actual percentages are a "trade secret" in all MSDS and SDS documents. I believe that the reporting requirements may have changed in the past few years. and that could be the reason it seems to have disappeared. I'd check but it's probably not worth it. I discovered the Ethyl Acetate component on a RECENT document listing products containing EA, but with no percentages given. I formulated a biobased solvent which had just 3% of a specific chemical which made a dramatic difference to the performance of the solvent in removing layers of lead paint. So it's hard to tell the impact of adding a small amount of a chemical on the final efficacy without being familiar with the chemistry, which I am not.

I think at this point, let's see what develops or dissolves..

A totally different outlook but why not take the person to court and get them to pay for a new covering, or you may well be able to get the original maker to fit a new covering and make the so called restorer pay the cost

No one has queried if its Veg Tan or Chrome leather, and removal be require different methods of removal depending on the leather

Unfortunately this is the US legal system and just wouldn't be practical. I used to live in the UK and it's a completely different kettle of fish here. Even if you win, it's unlikely you will collect unless you have a lawyer and that costs more than the jobs worth. Been watching "Can't pay, we'll take it away" and it would never work like that here.

BTW I was an avid Sporting Clay shooter and occasionally won the club trophy at the Christmas Common club near Oxford. I was out every Saturday and Sunday and have a custom Winchester of which only 500 were made for the UK market. I took lessons at H&H. 

Cheers!

I only started Clays when 60 so never any high expectations and mainly just shoot at local straw bale shoots, with occasional visits to Highlodge in Suffolk as championship sporting ground

I dropped it when I moved back to the States. Something just wrong about shooting under a clear blue sky in California is shorts, and a t-shirt. I missed the Hunters, Barbours, bacon butty made by the farmers the frost and the drizzle. It was out corporate sport, instead of golf, and my boss had a pair of matched Purdys which cost more than my house in Berkshire.
