Efficacy of various surface disinfectants on an irregular surface.
Representative samples of hard surface disinfectants were tested against Pseudomonas aeruginosa (ATCC 27853) on frosted glass rods. The same protocol was followed by two investigators on 100 rods for each product tested. Results showed Sporicidin surface disinfectant (Ash Dentsply, York, Pa.) and household bleach 1:10 to be most effective against P. aeruginosa. Lysol disinfectant spray (Lehn & Fink Products, Montvale, N.J.), performed similarly whereas Biocide (Biotrol International, Woods Cross, Utah) failed to inhibit growth on more than half of the rods treated. Failure of the iodophor may be attributed to the use of cotton-filled gauze, because cellulose is believed to react with nascent iodine.
