How To Get Dirt Out Of Glass Bottles
Heres what I have tried all involving scrubbing with a toothbrush.
How to get dirt out of glass bottles. Using a professional bottle cleaner is the best way to restore a bottle. If it is something like a Camelbak water bottle where you have to suck a valve may have been. Rinsing first helps remove the loosest debris and helps keep the water in the sink or plastic tub cleaner.
If the glass is fragile swirl gently. You mentioned in the comments that its a pretty large area so based on that. To get a more detailed look you can also paint the inside of the bottle.
Buy a bottle brush. I tried pouring out just the water but gave up. If you have a water bottle with just a plain screw onoff lid the seal may be broken.
Being underground for a long time exposes the bottles to water which stains them on the inside and outside the chemicals in the water do the staining. Once done dry the bottles with a very clean cloth. Then fill the sink with enough warm water to submerge.
But just make sure that it is fully covered in the Mod PodgeWater mixtures so it adheres to the bottle as it should. Any dish washing detergent will do. If you dont want to replace it find out where the leak is.
This occurs due to changes in the glass that occur when components of the glass are removed over time from the liquids inside the bottle. It also can happen to old bottles that have spent many years underground and were subjected to moisture. There were broken bottles these were thrown away using traditional garbage service but any bottle that was whole made it into this box.
