Describe the problem before buying a solution
Write down what changed: one wheel feels rough, several became noisy after a dusty session, or a recently reassembled wheel barely turns. These situations do not automatically have the same cause. Note when the symptom appeared and what work you last did. Record the skate, wheel position and bearing identification where available. Photograph the assembly before taking anything apart.
Do not begin with a timed free-spin competition. You need to understand a change in this wheel, not prove that it outperforms a friend's bearing. Compare observations on your own setup and avoid treating a long unloaded spin as a certificate of condition. A locked wheel, pronounced roughness or uncertain assembly is a reason to stop skating while you investigate.
Check what you can identify
Find the instructions for the actual bearing and the skate's wheel assembly. Some products have service instructions; do not force an unfamiliar shield open simply because a video shows a different bearing. Keep the wheel's bearings and spacer together in a labelled tray. If the symptom began immediately after wheel work, include assembly and spacer compatibility in your question to the manufacturer or technician.
Example: three wheels feel as before, while the one you remounted does not. Buying an entire new bearing set would skip an important clue. Instead, document that sequence and resolve the assembled wheel against the correct instructions. Do not loosen an axle below its required fastening condition to make the wheel appear to spin better.
Decide between service and replacement
Bones explains that dirty or noisy bearings can need cleaning or replacement. Use that as a decision fork, not permission to restore every damaged bearing. If the bearing is identifiable, serviceable and you can follow its instructions, a planned clean may be reasonable. If a part is visibly damaged, remains rough after correct service or cannot be confidently reassembled, stop using it and seek an appropriate replacement or assessment.
Make a simple worksheet with three boxes: instructions found, complete tools and approved products available, and enough time to finish correctly. A missing box means today's task is gathering information or arranging service. It is not a reason to shorten the process so you can catch the crew's session.
Do not improvise the chemistry
Bones specifically warns that adding oil to dirty bearings does not clean them. Follow the product maker's cleaning, drying and lubrication instructions rather than mixing household sprays. This guide does not prescribe a universal solvent, amount of lubricant or shield-removal method. A product approved for one bearing is not automatically suitable for all shields, cages and wheel components.
Read the cleaner's own safety and disposal instructions as well. Use the required ventilation and protection and keep the job separate from food preparation. If you cannot create an appropriate work area, choose service by someone equipped for it. Keep all containers identified; an unlabelled bottle is not a maintenance shortcut worth guessing about.
Finish with a resolved wheel and useful notes
Reassemble according to the skate and bearing instructions. Check the complete wheel, not only a loose bearing on the table. If it binds, has unresolved movement or feels unexpectedly different, postpone skating. Confirm the fault is resolved before a gentle controlled check on level ground. A trick session is not the place to decide whether the repair worked.

Quick answers
Will oil fix a dirty bearing?
Do not use oil as a substitute for cleaning. Follow the bearing maker’s service instructions, and stop using a wheel with unresolved binding or damage.
