The cheap sensor swab kit that saved me $120 in bench time
Tbh I bought a 10 pack of generic sensor swabs for $14 after my usual brand ran out and I had a Canon 5D Mark IV with a nasty oil spot on the sensor. The swabs actually worked fine, no streaks, and I didn't have to mail the body out or eat the cost of a shop cleaning. Has anyone else gambled on the no-name consumables and gotten lucky, or am I just asking for a scratched filter down the line?
