I would like some feed back on cleaning and swabbing of drains. What is the appropriate way to swab a drain, or a procedure for swabbing drains? I heard some just do the drain cover, some remove drain cover and swab the bowl and some even go down into the drain. Just looking for a solid proper way on swabbing drains.
We have a bit a drain problem with a couple of positive hits ( listeria) and a couple of trouble drains with reoccurring hits. The drain cleaning procedure is very general- collect debris, remove lid, clean out drain bowl, pre-rinse, apply cleaning solution ( HC-10-Ecolab) with dedicated brush, scrub down, rinse with water then apply a quat base sanitizer ( Boost -3200-3201-ecolab) by pouring from a 5 gal. bucket. Is there something different we should be doing???
Any advice, directions will be grateful.....
