Title: spot cleaner making red bleed???
Post by: Screened Gear on December 24, 2011, 05:15:08 AM
I have never had this happen before. I had a small pinhole and went to clean it out and the ink that was dry bleed a light yellow on the white shirt. This maybe the first time I have tried to clean red ink off white shirts. Does red ink always do this? Is this normal??? This is after going through the dryer so the ink is 100% cured.

red ink always gives us trouble when spot cleaning.

Yes, red ink can do this. In fact, even ink that does not "bleed" can become brittle as the cleaning chemical can leach out the plasticizers.

I try to use a common metal eraser shield, an absolute minimum of spray, and sometimes even a hairdryer immediately afterwards. (a vacuum spray-out station may also help dry out the area faster)
It can still screw up. Sometimes, it's best to blow out a sample, and then compare which is worse; the pinhole or the "fixed" version.

Reds and Black inks have always bled with spot cleaners as long as I can remember.

we put the shirt over a shop vac hose and spray it that keeps the acetone from bleeding into other ink. Oh yah turn on the vac, just make sure you vent well

You can always blot the spot with a good tape (block out or packing) which will usually lift small spots and ghost marks out. Works pretty good on cured or wet ink. 90% of the time we don't even use the spot gun.

Depending on the carrier or dispersal agent, spot cleaners can bleed certain colors.  Spotbuster has an alcohol carrier and evaporates very quickly.  The best I have seen.
Acetone, while inexpensive, is fairly flammable and a static charge can ignite it. I recommend any spot fluid over acetone.  Spotbuster #1 of course. :)
