Cleaning Grill Cloth

Great job. Love those speakers! Love those grills! Orange L36s are all too rare.

I had some new L36s back in 1979 or so, and the JBL owner's manual recommended Texize K2R spot remover by name, for cleaning the grill cloth.

As it dried..some of the black frame started to bleed through, so I have to figure that out....lol

Since the cloth is only glued to the backside of the frame, take plastic wrap (saran wrap) and tuck it in between the cloth and frame as far as you can. This will prevent the wood from getting wet and staining the cloth. After it's dry, pull off the wrap.
 
I hate to say it I thought that they looked ugly when you first showed them, but now, that they are clean they are looking so much better and I actually like them :)
 
I tried to get plastic wrap in there, but couldn't get in there far enough...getting them wet cleaning them loosened up the cloth, so I took them off and put them in the washer...came out spectacular...now I am putting them back on..will post pics later.
 
Cloth is re-attached and looking so much better and best of all..no bleed through...LOL

I periodically clean my speaker grilles, since I smoke and get residue on them, and I have had to clean other grilles for reasons similar to yours when doing restorations. I use a spray-on carpet cleaning solution--totall saturate them and let them sit in the shower/tub for a while and then just turn on the warm water and let it run on them to rinse away the crud and stains and excess soap. Then just let them stand in the shower/tub to air dry. If you need to (and I had to do this a couple times) you can fill the tub with an inch or two of warm water and add laundry detergent to the water and let them soak for a while before rinsing. Obviously, don't get anything that wet if the frames are wood, but all of the ones that I have dealt with have been some kind of plastic or fiberglass frame.

Looks good! What exactly was your process so far?

I started using upholstery cleaner..rubbing with a damp cloth, rinsing then vacuuming. That worked great, but as it dried, black from the frame bled through around the edges so I took the cloth of...sprayed it with pre-wash andput it in the washer on cold...then let it hang dry. Since they had been on the frames since new...the original creases from the edges of the frame were still there....I aligned up each corner to its original position...put a small staple to hold them in place. Then stated gluing each side one at a time...starting in the middle and working my way to the corners. Once all four sides were glued and dried...I removednthe staples on the corners and glued those down.
