I’ve only washed a couple of Tough 1500 V2 parts with RWS. The surfaces remained a bit tacky, but this could have been an issue on my side with the saturation. After washing, the parts performed as expected. We’ve since moved on to using IPA. Maybe this thread of mine helps you out - I remain rather unconvinced about the performance and usability of RWS. > [@Formlabs Resin Washing Solution - Practical Use](https://forum.formlabs.com/t/formlabs-resin-washing-solution-practical-use/45323/7): > > Thank you for the points. I find it interesting that point 2 contradicts the usage guide on the [support site](https://support.formlabs.com/s/article/Formlabs-Resin-Washing-Solution?language=en_US), which states that no agitation is required. Is there perhaps updated guidance on the rinse time as well? How do the Budapest HQ colleagues manage rinsing water and RWS saturation? Are all of these monitored using special hydrometers? --- _[View the full topic](https://forum.formlabs.com/t/tough-1500-2000-v2-form-wash-or-alternatives/46800)._
