<p>I've occasionally had issues with excess filament residue getting stuck to the print bed. <a href="https://3dprinting.stackexchange.com/questions/78/how-can-i-stop-my-print-bed-tape-from-sticking-to-the-filament">There are ways to prevent this</a>, but sometimes even these precautions aren't enough. Over time, residue can build up. I've observed this in some printers, though not others.</p>

<p>Are there any techniques to best clean print beds? In the past, I've used various typical cleaning supplies, with different degrees of success. However, I don't know if this will lead to damage to the printer over time.</p>

<p>The printer I'm using has a glass print bed, which I occasionally partially cover with blue painter's tape during printing.</p>
