What can I use to get salt marks off of my tubes ? I haven't cleaned them with salt in months and I still see a big salt stain right at the top of both my tubes. I soke them in zep for a day or so and there spot less (meaning no resin) but I still have salt marks. I've also tryed iso with no salt to remove them and still no luck, Any tips ?
ISO and salt wash as usual. Drain out the mixture after shaking it around. Pour a little amount of white vinegar into the piece. Shake it up good. Rinse it out. No more hard water stains.
