Separate dry debris removal from washing or solvent soaking, using exact disc ratings and a practical removed-disc cleanup routine.
Read Shore scales, pad thickness and construction to choose a compatible sanding support without treating a hardness number as a finish guarantee.
Check connectors, bypass settings and the complete extraction path before blaming the abrasive.
Identify a sheet orbital sander, random-orbit disc sander or detail pad, then match the abrasive shape, attachment and extraction pattern.
Decide whether bare wood needs a final hand-sanding pass, keep the approved finish grit and recognize marks that need earlier correction.
Compare abrasive methods using accepted surface area, usable pieces and total working time before committing to a larger purchase.
Identify disc-loop, pad-saver or backing-pad separation before buying replacement discs.
Check support and edge contact when changing abrasive format instead of judging only by dust extraction.
Choose backing by bend, support and scratch control instead of assuming stronger backing always gives a better finish.
