Electro-sanitizer
- Electro-sanitizers are internal components from the cartoon portion of the Generation 1 continuity family.

Much as white blood cells do in humans, electro-sanitizers keep Transformers' internal workings clear of foreign invaders. They take the form of electrically-charged rings which travel through Transformer infrastructure on cables, arcing electrical discharges as they go.
Fiction
The Transformers cartoon
As Perceptor, Bumblebee and Brawn were moving around inside Megatron's body, having shrunken themselves with Perceptor's transmat reduction beam, they were threatened by the approach of a number of electro-sanitizers. Perceptor warned the other two Autobots to keep down, however Brawn was sick of hiding and decided to fight back. After a brief struggle, he successfully destroyed the two electro-sanitizers. The three Autobots were subsequently able to proceed to Megatron's evil brain unhindered. Microbots
