I recently tried cleaning a glass build plate with Dawn dish detergent and rinsed it thoroughly but the PLA wouldn't stick until I went over it with iso. I think it must have left a residue.

For PET-G I'm been using the Aqua-Net hairspray on one side of the bed.  The other side is kept hairspray-free and is cleaned with IPA.  My 95% is now diluted to about 71%, and IPA is not yet in the stores.

<p><strong>Ethanol</strong> (Ethyl Alcohol) should work just fine as long as it's around 80% or more. It's very similar to isopropanol as a cleaning solvent. What you're basically doing is removing any stray grease from the bed with a solvent that evaporates quickly. </p>

<p><strong>Methanol</strong> would also probably work. It's very poisonous though, and shouldn't come into contact with your skin, so it requires a bit more careful handling.

<p>Look for alternative sources, for example, methanol is often sold as de-icing agent for pneumatic brakes on trucks. Just make sure it's pure alcohol without anything funky added. </p>

Beware of methanol, it can turn you blind. It is easily absorbed by the skin.

Good point, just don't get it on your hands, don't drink it (10 ml will cause blindness, 30 ml will probably kill you), and don't use so much that you're huffing vapors and you'll be fine.

Methanol is not as bad as everyone says.  As a matter of fact for severe ethanol poisoning (over-drinking) they give you methanol because it flushes the ethanol.

You've completely misunderstood something, the treatment for methanol poisoning is ethanol, not the other way around. Methanol is very poisonous, but it won't kill you if you use it responsibly.

I've been using ethanol exclusively as that's what I had on hand. It's only 70% but it still seems to work well. Coupled with a micro-fiber rag it keeps the print bed looking fresh.

Why not order it on Amazon? Looks like they can get it for you and you don't have to go out to get it.

When I looked yesterday, it was 1/2 that amount ... that said, *beggars cannot be choosers*. Besides, anything which acts as IPA is going to cost like IPA, considering the current world circumstance.

# PRUSA likes the bed to be cleaned with isopropyl alcohol. What else should I use?

(Asked by: username_0 on 2020-03-26)

I have the original Prusa i3m3 printer. Prusa recommends cleaning the bed before each print with isopropanol (isopropyl alcohol), with only occasional cleaning with acetone. The textured bed prohibits using acetone.

Given the SARS-COV-2 situation and COVID-19, isopropanol is impossible to find, and will not be in stock on shelves in the US for months.

What would you suggest as an alternative that might still be found on store shelves?
