    "0.45 MPa is the lighter load on the test bar. 1.8 MPa is the heavier load. A higher heat-deflection temperature means the bar got further before it bent. It does not describe detergent, spray, or a stacked cycle.",
    "Food against the plastic is [food contact](/answers/food-contact). Heat in general is [heat resistance](/answers/heat). Slow bending under a constant load is [creep](/answers/pla_creep).",
    "Comments that name PETG, ASA, or PP are experiences. They are not a manufacturer dishwasher rating. Polypropylene printing is [PP](/answers/pp), and that page does not add a dishwasher claim either."
  ],
  "pros": [
    "Each heat-deflection pair names the load and the ISO 75 test, with the date the sheet was checked.",
    "No spool is called dishwasher-safe, because none of the cited sheets say that."
  ],
  "cons": [
    "A comment that PLA will not survive a cycle, and a comment that PETG will, are both comments. They are not copied onto the datasheets.",
    "ASA and PP show up in a comment. Their heat figures are not relabeled as dishwasher results here."
  ],
  "community": "One comment says PETG can do the top rack if the blend is right, that ASA is probably the better performer, and that PP is the other option. Another says PETG yes and PLA will not survive a single round. A third says they would not worry about food-safe if the part is not touching food. None of those is a datasheet.",
