6. Examine the plate. If you see any sample or matrix
residue, oil, or fingerprints on the plate, soak the sample
plate in a working solution of laboratory detergent in
water (for example, RBS 35 detergent from Pierce or
LIQUI-NOX
from VWR) for the minimum time required
to remove samples.
CAUTION
Do not leave the sample plate in detergent for longer
than 10 minutes. Longer exposure can cause the
bottom holders on the sample plate to corrode. Do not
sonicate sample plates or use acid to clean sample
plates. Both can alter the surface of the sample plate,
and reduce the quality of the data obtained.
7. Rinse the plate thoroughly in deionized water.
8. Allow the plate to dry at room temperature in an area
where it will not be exposed to contaminants. Allow the
plate to dry completely before use to obtain the maximum
hydrophobic effect.

To clean gold and stainless steel sample plate surfaces:
1. Rinse the plate with a squeeze bottle of solvent.
2. Rub with a lint-free lab tissue to clean.
3. Rinse with deionized water.
4. Examine the plate. If you see any sample or matrix
residue, oil, or fingerprints on the plate, soak the sample
plate in a working solution of laboratory detergent in
water (for example, RBS 35 detergent from Pierce or
LIQUI-NOX
from VWR) for 5 to 10 minutes.
