If you have an iFixit battery kit with liquid adhesive remover, it's time to get it prepped.

Alternatively, if you are using the hot iOpener method, skip the following three steps.

iFixit adhesive remover contains acetone, a mild skin and eye irritant.

Wear eye protection when handling and applying the adhesive remover. (Eye protection is included in your kit.)

Do not wear contact lenses without eye protection.

Protective gloves are also included in your kit. If you are concerned about skin irritation, put your gloves on now.
