Removing paint drip from grill cloth

Postby Jim Barth on Sun May 02, 2010 2:17 am

I picked up an amp that has a smallish spot where a white drop of paint must have dripped on the grill cloth. What is the best way to remove this?

Thanks!

coincidentally, I have the same thing going on with a deluxe I just got. How big is
your drip??

We can compare approaches if you like. What I am going to try and avoid is any
method that will make the problem worse which I can see happening in 2 main ways:

1. spreading the paint around, making the stain worse
2. damaging the cloth itself, creating a hole, staining or bleaching it

So this is going to mean starting without much in the way of chemical agents.

Depending on its own chemical makeup, the paint *should* be simply sitting on top of the
the grill cloth itself - as opposed to having penetrated into the strands that makeup the
cloth weave. So I will start with using a fine tipped instrument to try and see how easily
the paint will chip off of the cloth, making sure not to stretch or pull the cloth too much.
I am betting that the paint is not designed to bind to plastic, and should therefore fall off
of there - but this would be a SLOW procedure, not a quick fix.

I'll report back after this first step. By the way, the heaviest chemical cleaner I have ever
tried on this cloth is 409 and I got good results on the removal of more standard dirt, and
stains like from spilled beer or coke.

I would NOT want to start with 409 in case it breaks up/dissolves the paint and then I get a
smearing effect that spreads the stain and makes the clean up a larger problem.

hit me back with your thoughts! and post a pic if you would. Here is a link to mine

I've used duct tape to gently remove paint from the grille. Has worked on numerous amps I've owned or worked on. Most recently my '61 Super. I've also used a small pick to pry spots off that the tape will not remove.

Thanks! This will be attempt #1. I don't know if I'll get a chance today, but I will give this a try.

Well fortunately for me, and unfortunately for you, I just have one drip near the very bottom of the grill.

Jim

thanks for your concern!

I just got finished with a first pass and have gotten good results with the following:

I used a very fine tipped mini flat head to break up the paint in the weave itself,
then I used a dry toothbrush to continue to disrupt any of the light bonds holding
the paint there and to start the pieces to falling off. Then a shot of compressed air
to get the rest that was loosened by steps one and two. Repeat as necessary and
then a 409 treatment over the entire grill for a cleaning and the result is a uniform
and clean look.

What is a "very fine tipped mini flat head". :)

I'm thinking you are talking abut a nail?

Glad it went well you had a big area to work on.

oh, my bad! I think I wrote that response in a little haste.

I used the smallest flat-head screw driver from my miniature screwdriver set.
The tip of the screwdriver is small enough to let me root around between the
threads that make up the weave. The paint sort of broke apart, broke off the
threads and then the dry toothbrush and compressed air finished it off.

There is some very fine powdery residue that is still on the threads where the
paint had been, so I am thinking that the 409 treatment to the entire cloth
will take care of that and give the whole piece a uniform (and clean) look!

The duct tape thing did not work on my drip at all, but luckily just some elbow grease and a wet cloth did the trick!

Thanks for filling me in on the screwdriver. That's where I would have gone next.
