You can wash the print in an ultrasonic bath [1] in isopropyl alcohol (IPA).

Then cure using a UV LED strip (5m w USB plug ~2 EUR) inside an empty can (another 2-5 EUR) and a solar-powered rotating base [2].

The light from the LEDs is cures as well as powers the base. All four will set you back less than 50 EUR.
