Hi,

is there any trick for cleaning those burned-in textile and gaffer tape residues from the outside of high wattage fixtures (such as fresnesls and PARs)? I've tried denat. alcohol and ammonia with lots of scrubbing :angry: and only little success - maybe there is something a bit more effective? Shouldn't be so strong that it peels the paint off, though...

Greetings,
Marc

Acetone.
Try to use clothespins in the future to avoid the residue.

but Acetone does peel the (black) paint, does it? (will do wonders for the newer ARRI style aluminium fresnels, though)..

100% agree with the clothespins... I'm amazed anyone would use tape on these. This was done by a previous owner...

I'm not endorsing this, but have you tried using Goo Gone? I've used it to take Gaff tape adhesive off metal surfaces without any paint peeling.

I've used 3m Adhesive Remover for years on all sorts of projects.

You might have a problem with any remover if the adhesive has been carbonized...then it might work to try a household oven cleaner.

Hi Marc,

try heating the stuff with a hot air gun. That should help in some cases!

Cheers, Dave

try rubbing some mayonaise into the affected area, leave it for an hour or so, then scrape off. apparently the oil content helps soak through adhesive. If it is totally burnt in, you may have some trouble with this method. A houshold cleaner like 'astonish' may do it. its designed for ovens, although be careful, its slightly abrasive and could scratch the finish.

Good ideas guys, thanks!

The stuff has burned in (the adhesive is not sticky any more).. at the buttom where it's colder the residues still have their gray color, at the top they are sort of brownish, probably partially carbonized. I'll keep you updated on what works best.

(I'm still puzzled about the amount of tape used on those fixtures... you should think people would learn after seing the tape burn in the first time, then use something different for attaching stuff to the fixture, but no...) :angry:

Then be sure to save that lamp until just before lunch, so the whole place smells like a sub-shop.

OK I tried various stuff on this... thanks to all for your suggestions.

The oven cleaner really does wonders... spray it, and within seconds you can wipe the residue off. This works for most of the tape residues and does not seem to damage the paint. However, the package says it can damage paint and metals such as aluminium, so try it first at some small pattch not readily visible. As an added benefit this only has a very light alkaline smell. This cleaner works best for patches where the glue really has burnt in and carbonized, and it will also remove rust.

The oven cleaner won't work for some of the resiudes, what worked best here was ammonia. It smells, it attacks the skin, so it's really no fun at all, and you still have to do lots of scraping/rubbing.

For greasy residue, use printer cleaning spray or cold cleaner (it's the same, actually). It' a mixture of solvents and the residues will run off the parts within seconds.

Greetings,
Marc
