Does the stain-resistant shirt actually work when tested?

The clip shows a comparison test between a regular shirt and a stain-proof shirt. The tester initially demonstrates a regular shirt that fails to repel stains, stating "Yeah, that sucks" about the normal shirt's performance. Then they transition to testing the stain-proof shirt, saying "Now let's try the stain proof." While the complete test results aren't provided in this short transcript, the clip appears to be evaluating whether the stain-resistant technology actually works against substances like red wine and oil-based paint as mentioned in the description.
