Tide To Go is going farther than ever before. Tide To Go pens, wipes and Tide Rescue Spray are taking off with SpaceX CRS-25 this summer to the International Space Station (ISS).

This cargo resupply mission follows Tide Infinity’s send off last December and is part of the brand’s ongoing efforts (“Mission PGTIDE”) to develop low-resource cleaning solutions. While the Tide Infinity experiment focused on fully degradable detergent and water recovery, the Tide To Go experiments investigate stain removal at the surface level.

On the ISS, astronauts will treat pre-stained fabrics from Earth and fabrics they stain in flight with our Tide To Go products. The series of stains tested are some that astronauts commonly encounter, such as Sriracha, coffee, fruit punch and oil. The main objective of the experiments is to understand how microgravity affects product stability and stain removal efficacy, according to Tide Research Fellow Mark Sivik.

“Because there’s no gravity, there’s nothing to collapse the surfactant, and we might get more efficacy out of the surfactant,” Sivik said. “[Without gravity] we’re only fighting the surface tension of the stain to the fabric. Depending on the results, we’ll see what we need to modify for a particular staining group.”
