De-icer to clean glass print bed

Topic title about covers it.

I was having a lot of problems getting prints to stick to my glass bed (PLA), I thought that it was pretty clean but having read on here that cleaning with acetone or isopropyl alcohol could help I started hunting around for something in the house to use. Found a bottle of car windscreen de-icer and thought I would give it a go...

Works brilliantly.

One squirt, quick wipe off with a sheet of kitchen roll and prints are sticking brilliantly.

My de-icer is labelled as "contains isopropanol".

George

isopropyl alcohol and isopropanol are the same thing

Thought they must be pretty close hence I thought it worth trying, wasn't sure what else would be in there that might spoil the effect. For me de-icer is a lot more readily available and cheap...

pla is the so easy to print on glass. no need for chemicals or anything.

buy some PVA glue. mix a little water. heat bed to 62C paint it on wait to dry . Print away will stick like crazy. to the point u then have to cool to 30C to remove the print.

You can risk it and get around another 3 - 6 prints from the same PVA but i like to clean away with glass cleaner and some kitchen paper. then another spray of glass cleaner and a micro cloth then repeat. Never had a problem with it this way.

My experience of the de-icer is that the print needs to be cooled to this same kind of level to remove. And it seems like less effort than what you describe.

One squirt, wipe, done.

I have done it before turning the heat on and during and both seemed fine.

It's all voodoo. Follow a specific pattern and it works, but you don't actually know which part of it is really working.

It's not something in the De-icing solution. Prints stick to clean glass better than dirty glass, that's all (if the temperature is set right). Any glass cleaner that doesn't leave a residue works fine too. I personally get by fine with generic Windex.

I don't use anything on my glass, just heat it up to 60 C and print then let it cool and the parts pop off. Clean the glass with the razor blade then print again. Never used any chemicals and never had any problems.

What do you do when using ABS ?

I just this week needed to clean the glas on a machine I took to the office, and I didn;t have alcohol, so I used Goo Gone, which I believe is mostly citrus terpenes and petoleum based others.

I applied it while the bed was hot, and the result was noticeable. The stickyness of the ABS remains, even after cooling. The glass was BSG.

Yes well ABS is another messy story - I have only had ABS prints work with diluted ABS as a base so I have to get stuck in with the acetone and slop it around to form the base for the next print. There aren't enough reasons to want to use ABS that often, I use PLA 95% of the time.
