View Full Version : Paper contamination problem
05-24-2001, 12:29 AM
Problem: I am returning to a portrait 'paused' for 8 years. I am finding odd irregularities as I bring more and more glazes in. Like the surface has picked up a light layer of oil - here and there. In some areas this has produced some pleasant effects, in other key areas, a blemish. Anyone know how to remove this contamination? I considered a Q-tip with very diluted dishwashing liquid. To scared to try it yet though. This piece has family sentamental<sp> value so it's worth it to try something. Any suggetions?

Oh dear..not sure what could have caused this and hope someone else can be more helpful. My first thought was possible fingerprints. The oil on your fingertips can cause this - that is why we are cautioned not to test dryness on a painting with fingertips (use the side of your hand instead).
I will be anxious to hear others comment on this one...good luck ! http://www.wetcanvas.com/ubb/smile.gif Carol

Hi, Im with Carol. fingertips.If you saw how much body fat comes off in say a swimming pools filters just through usage you would be ill. Carefull if your using detergent you dont bleach.

Q.E.D. my dear Watson. The culprit is nabbed. I put in a wash in a new section today and viola a perfect child's handprint appeared as if by magic. The little 'villian' fessed up as the evidence of size made it impossible to deny. Though my table is off limits, my chair is loaned out by favor on occassion. Confession revealed that it was returned with occupant taking a ride and the table and resident portrait was used as a push-point for spinning. Sherlock Holmes would be proud.
But I have taken myself to task about dryness testing via fingertip. I keep a clean sheet of paper under my arm at all times to protect the surface. Seems almost hypocritical to allow my fingers to get away with it. LOL.

O.K. I tried the Q-tip idea. Here are the results:
Absolutely do not scrub - the soap does quite a number on the sizing of the paper. Then when you bring a wash back over you get an intensely dark patch.
The following method did work, however: Diluted soapy Q-tip done as a light application was allowed to dry. Then rinsed by gently swabbing away the soap. Allowed to dry again...repeat. This worked great. Painting salvaged! Yeah

try using a bit of UN-DO on a q-tip. I use it to remove glue and marks and it doesn't lift paint color. you can get it at office depot or staples i think.

Lots of luck with the different suggestions. If nothing else at least the hand print is in the family and can become part of the story of the painting. http://www.wetcanvas.com/ubb/smile.gif

I had to remove the clear, full handprint due to its location, but I am keeping the little single fingerprints that are turning up in the background area and sides. The portrait will probably be passed on to my daughter (now age 11) who is the child in the portrait, but she will have a piece of her little brother's history mixed in too. Actually, she will probably find it to always be a fun reminder of when she herself committed an 'offence'. It is fun family history now and we all laugh about it but when she was 3 she climbed up to my art table and applied brilliant orange prismacolor to a watercolor commission I was working on. I lost only 11 hours investment - believe me it could have been worse because at the moment she was 'critiquing' I was on the phone to another client letting them know that their order was finished. If Melody would have selected that one instead of the one she did I would have lost a finished piece that had about 200 hours (4 months labor) involved. I didn't even get a bit mad. I just sighed a deep sigh of relief and counted my blessings. She did, however, recieve solid instructions about leaving mom's art table alone. Ditto little brother!
A tricky problem, a lesson for us all to learn,
