Vintage Tweed Water Damage Repair
« on: June 06, 2024, 07:59:06 pm »
Any thoughts about minimizing/removing the stain from years ago water damage to old tweed?
Without replacing the tweed.

Thinking some type of fabric nourishment might help.
It is not lacquered.

Is that an old suitcase? Man, have you seen the new stuff out today? Some of them even have wheels!   :l2:
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Yeah, I wouldn't want to carry that one around . . .  But I like the old school look!

As for mitigating the water stains, it's tough to do.  My method is to soak a small area with distilled (or RO) water, then dry it by dabbing it with a microfiber cloth repeatedly until the area is just damp.  You're actually trying the draw the dirt/stain out of the tweed into the microfiber.   Repeat as needed.  Need lots of microfiber cloth.

This does work -- of course depending on the stain -- but is tedious.   I have used various household detergents (dish soap is the safest) as well as diluted vinegar on occasion when desperate for a result. The key is the flood a small area at a time, and allow the microfiber to draw the water and dirt out.  If you do use a detergent, make sure you rinse the area well and dry it using the microfiber cloths.

Suggest trying this on an inconspicuous spot first.   Your mileage may vary!   Take care.

It's a battery powered Zenith Radio
Very complete, waiting for restore.

The approach to portable music in the day.

Question - should it live on as an AM radio or a guitar amp?
Not technically, but from a preserve the past standpoint I always struggle with this.
I would use the amp and not so much the radio, But mostly for display either way.

I'd fix the radio first and then decide. Either way I'd probably just accept the water stains as part of the patina.

I'm with Steve, once it works, you can decide to jack-in to the audio section, with an 8-track, or guitar.

OK, I give, that is a really cool looking piece.   It looked like a big suitcase when I first glanced at it.   

I agree, repair is the way to go.  A simple cleaning will suffice.

Cool piece.
