# Is any filament safe in a dishwasher?

PolyLite PLA's datasheet lists a heat-deflection temperature of 60 °C (140 °F) at a 0.45 MPa load and 58 °C (136 °F) at a 1.8 MPa load. PolyLite PETG on the same ISO 75 test is 78 °C (172 °F) and 75 °C (167 °F). PolyLite ABS is 100 °C (212 °F) and 98 °C (208 °F). None of those sheets call the filament safe for a dishwasher, and a heat-deflection test is a bar bending under a weight, not a wash cycle.

No filament on this page is called dishwasher-safe. The numbers below are heat-deflection temperatures from Polymaker's sheets. They say when a test bar bends. They do not say a basket, a detergent, or a dry cycle is fine. Whether plastic may touch food is [food contact](/answers/food-contact). [Heat resistance](/answers/heat) and [creep](/answers/pla_creep) are the other heat pages.
## Heat deflection, with the load named

[PolyLite PLA](/brand/polymaker/polylite-pla), checked 21 October 2026, is 60 °C (140 °F) at 0.45 MPa and 58 °C (136 °F) at 1.8 MPa, ISO 75. [PolyLite PETG](/brand/polymaker/polylite-petg) is 78 °C (172 °F) and 75 °C (167 °F) on those same two loads. [PolyLite ABS](/brand/polymaker/polylite-abs) is 100 °C (212 °F) and 98 °C (208 °F). The 0.45 MPa figure is the lighter load. The 1.8 MPa figure is the heavier load. A part in a dishwasher is not that bar, and none of the three sheets uses the word dishwasher.

[How to print polypropylene](/answers/pp) is the page for PP. It does not add a dishwasher rating either. PolyLite ASA's heat-deflection pair is on [ABS versus ASA](/answers/abs_vs_asa), and that page does not call ASA dishwasher-safe.
## What the community says

[a Reddit thread in r/prusa3d](https://www.reddit.com/r/prusa3d/comments/1vwlqsq/) says PETG, if it is the right blend, will do on the top rack, that ASA is probably the better performer, and that PP is the other option if you can print it.

[a Reddit thread in r/prusa3d](https://www.reddit.com/r/prusa3d/comments/1vwlqsq/) says PETG yes, and that PLA will not survive a single round.

[a Reddit thread in r/prusa3d](https://www.reddit.com/r/prusa3d/comments/1880k5e/) says that if the part is not touching food, that person would not worry about food-safe.
