The best way to thoroughly clean the inside of globes?

[KittenChops]

Topic says it all. I've tried everything but it's a pain. Even bottle brushes just don't really get the job done because of the angle required. Any suggestions or experiences? Thanks fellow goo heads!

Simple Green. Let it soak for a few days. Manually clean off any remaining residue. If your wax is still sticking it's the wax not the glass.

Thanks for your reply. I'm not trying to clean off any wax, just odd white residue on the inside of the glass that makes the globe look dirty.

That's probably residue from the surfactant in the master fluid. The only way I've found to remove it is with physical contact. No cleaners remove it easily. You also have to drain the master fluid otherwise the residue will make it cloudy. You can try to magnets with one wrapped in a cloth to wipe it away. The best way I've found to get 100% of it is to completely empty the globe, fill it with soap and water and a paper towel then use a flexible brush move the paper towel around to wipe everything away.

The magnets is a good idea!

Fish tank cleaner?  I have never tried but they use magnets and a small magnetic scrubber to remove algae from the inside of the tank.

they go on the end of your battery drill
Although, if there is stubborn reside, its best to soak them ovenight in mean green or simple green

I often had the problem that the residues arent removed but smear around in the bottle so in fact paper towels are best. a sponge is useless as you cant remove the smeary stuff from it.

I got one of these( KUWAN Bottle Cleaning Brush... https://www.amazon.com/dp/B06ZZ1R13N?ref=ppx_pop_mob_ap_share ) for my 32oz Spencer's lava lite brand lava lamp, it had cloudy master fluid I opened to filter it back clear and found the wax was a jelly type of texture when it was completely cooled down and it would not solidify. I heated it up with just the wax in the bottle and poured it out, then I used some isopropyl alcohol and the bottle brush to clean out the inside of the bottle, I alternated between the IPA and a liquid dish detergent with a little added sodium lauryl sulfate with 150°+ water to rinse the bottle out between cleaning solutions, I also washed the brush off separately so it wasn't just re-spreading the wax residue. After I felt like I had gotten the wax completely cleaned out of the bottle I rinsed it out with some acetone to make sure there was no wax or oils left on the bottle. Then I washed it again with soap rinsing it in progressively colder temperature water until it no longer made bubbles when it was shaken and pored out. After the bottle was air dried I added some sodium lauryl sulfate to recoat the glass surface to prevent future wax from sticking to the bottle.
The bottle brush is made out of a type of smooth foam cut and twisted around a flexible body kind of like a huge pipe cleaner made of craft foam type of material, instead of nylon bristles or coated sponge that doesn't work to scrub the inside surface and just pushes it around inside the bottle. It made it easy to clean the brush off so it wasn't re-depositing the wax being cleaned out/off.
