content: Hi guys! It was amazing to see so much support from you guys in an earlier post I made. It really gave me some boost and I found out I had forgotten a lot of things I used to do few years ago. I used to play keyboard and few years ago after a bad exam scores I gave up alot of things I considered distraction. I gave my keyboard to a friend so I wouldn't waste my time playing it. Now I have brought it back and I want to play and learn it again when I am not in mood to do anything else. Obviously my friend didn't take proper care of the instrument and noe it's all dirty. I can clean everything else but there's a fabric like material over the speakers and it looks filthy.Its like something was poured on to it. How do I clean it? Any has any experience with clean fabric over speakers? I don't want to do trial and error and ruin it. I need those clean because I make videos and it looks filthy on videos.

content: You generally dismantle enough to get the speaker covers off so that they are on their own or with only plastic on the surrounding areas, then simply use some water in a spray bottle to rinse the cloth, and let dry. That removes most of the dirt, and if there still is then another rinse and some scrubbing lightly with a new paint brush will remove more. after that you start to get aggressive, starting with another wash with the brush and a drop of dishwashing liquid in the spray bottle, then a thorough rinsing and let dry. that will get rid of most light stains and not harm the by now fragile cloth too much.If the cloth is torn then go to the haberdashery and get some black T shirt material and recover it, stretching the material to make a smooth surface.

OK the wholesaler is 20km from me, and the nearest agent 200km, but they do deliver within a week when you want more, and a pack of 200 do last quite a long time. They are also great for fish tank filters, makes the fish appear to be floating on nothing when they are working well.

content: Often those covers are on a removable frame. If so, just take them off (still on the frame) and wash them gently in the kitchen sink. The 'cloth' is usually synthetic (on anything less than 50 years old) and doesn't absorb water.To dry, place flat on a towel and dab the reverse side with another towel until you've got it reasonably dry, then just let time do the rest.I've done this successfully a fair number of times with no mishaps. Removes dust, spilled coffee and cigarette smoke residue. The first time I tried it was with covers so far gone that I couldn't damage them further and if it hadn't worked I'd have just recovered them. As it was, they came up spick and span and are still good to this day after a couple of further washes..Just take a good long look at the materials used for them beforehand, and if you've any doubts try wetting a corner of a folded-over piece as a test before you get fully stuck in.
