So, acetone will not work if I'm using PLA?

After doing more research, I stand corrected.  Acetone will dissolve PLA, but it is less efficient that ABS.  It would also turn it white so it is not used for standard printing.  I will edit my answer.

As Eric Johnson says, Acetone will work with PLA, but I've had just as much success with hot soapy water and a sponge on my glass surface.

<p>My usual solution for cleaning the glass bed on my printer is a glass scraper (basically just a razor blade with a handle on it):</p>

<p><a href="https://i.sstatic.net/03af0.jpg" rel="noreferrer"><img src="https://i.sstatic.net/03af0.jpg" alt="glass scraper"></a></p>

<p>Regardless of what kind of filament (abs/pla/nylon) or surface treatment (glue/painters tape/abs slurry) I've used the glass scraper always takes it right off, and with the style I posted a picture of the blade is flexible and thin enough it's also useful for peeling up the edge of prints that are stuck to the bed.</p>

I have just now used this exact tool and managed to make a cut into the print bed itself. So a word of warning for everybody, be careful if going this way

<p>When I print PLA on glass plate, I clean the glass with cold water and dishwashing liquid. Cold water! And no wipe! Cold water should take all dishwashing liquid "to the ground".

<p>But of course it doesn't fix problem of cleaning HB after print. To reduce this  problem I use glue stick (paper glue). I don't know if it's common but I do like this technique.</p>

<p>So having clean glass I spread (grease) some glue stick. It doesn't really matter if HB is cold or hot. This gives me a VERY strong adhesive force between the extruded filament and the glass. It's so strong that there is almost no way to detache it by hand. I use a paper knife.</p>

<p>Now you still have thin layer of glue and you can print again / add another layer of glue (but not more than 2..3 times) or wash it with hot water. After few times it's good to clean it again with dishwashing liquid and cold water.</p>

<p>This technique is amazing.</p>

There are too many types of bed material (glass, aluminum, granite, ceramic, plastic, PEI, PET, specific manufacturer material, plastic, garolite, etc) with too many adhesion methods (Kapton, slurry, tape, glue, etc) to be able to answer this.
