Official Luthiers Forum! :: View topic - Hydrogen Peroxide for Blood Stains?

I usually just put down 5 mil plastic for a pre-planned shot, but sometimes that is way too much of a tip-off. Hydrogen peroxide will always have some bleaching action on natural fabric, but usually a weak solution will not penetrate too much below the surface on lighter woods. I would recommend you use a scrap piece of the wood in question and try out from-the-bottle and dilute solution, taking care to neutralize.

Testing on scrap is not a bad idea... but, I don't plan on bleeding on it first. :roll:

It would be helpful that any suggested cleaning solution also remove sweat and tear stains as well.

I know vinegar works well for dried blood stains on fabric but I don't know about wood.....Mike

I was thinking of that Chinese legend where some guy had to make the best sword for an Emperor, and if the Emperor didn't like it he would be beheaded. So his wife threw herself into the molten steel and the steel was made into a sword, and it turned into the best sword ever made.

Maybe someone did the same with guitars... you know sacrifice someone to put his/her soul into it...

It doesn't normally go far into the wood...finish sanding will remove it easy, unless it was a big pool. It happened to me on both guitars I made.

I need to remove a blood stain from my spruce sound board. I thought I remembered that hydrogen peroxide could be used for this purpose. Have you used this to remove blood stains and what concentration do you recommend? ...50% ...25%? I don't want to create a bleached stain instead of a blood stain... Is this a good thing to use or is there something better? Thanks, Steve

Be careful putting your blood on the test piece!

Okay, someone must have tried this before... I'm sure I'm not the only one to have cut themselves and bled on the work. I do it pretty often.... I don't care about bleach stains on my clothes. ... I mean on the top... I figure that if I use a Q-tip with some dilute H. Peroxide it should do the trick. I just thought I'd post the question to get some advice... Testing on scrap is not a bad idea... but, I don't plan on bleeding on it first.

How about a very sharp card scraper or very finely set plane to just slice off the top layer where the blood dripped? I wouldn't imagine it would soak in real deep... The trouble with Blood is the iron in it... and you might be able to change the iron oxide color from red to black... It's still there until you figure out how to get the iron back up off the wood.... Thanks

Can you flip the top over and make the blood stain side on the inside?

You can all have a laugh at my expense on this one! I wish I had known about some of these fixes when I bled on the top of the very first guitar I ever built, way back in the early 1990's. In those days, I couldn't even imagine something like a discussion forum. The internet was out there, but most of us didn't know how to use it. Nor did most of us have the connectivity required to utilize the internet. Sometimes, progress is a wonderful thing. (So is technology in general....whenever it works.) Patrick

Leave it... You can then tell your customer (if its a commission) that you've put your sweat and blood and soul into the guitar, and it will worth a LOT more a few years down the road.

I think we've all have bled on our work. I always think of it as the makers mark. Some day someone will figure out how to clone someone from a dried up blood stain and we can use a Stradivari and get old Tony to show us the Cremona secrets.

It doesn't normally go far into the wood...finish sanding will remove it easy, unless it was a big pool. It happened to me on both guitars I made. Alan
