MORE CLEANING TIPS
SANITATION
Sawyer recommends occasionally sanitizing your filter. To do this, backwash the
filter with a standard bleach solution (fragrance free and no more than one cap of
bleach per quart of water). Let air dry and in a cool dry place before using.
CLOGGED FILTERS
If your filter is still flowing slow after backwashing, soak the filter in hot clean
water (not hotter than you can put your hand into) for about an hour and then back
flush using hot clean water. REMEMBER to backwash FORCEFULLY! When using
the syringe, do not be gentle, it will only form paths of least resistance instead of
blowing out the particulates that may be trapped in your filter.
CALCIUM BUILD UP
If after above steps your filter still seems to be clogged, it could be dried calcium.
Soak the filter in vinegar for 1/2 hour and then flush with hot clean (not hotter
than you can put your hand into) water. Repeat until the flow is restored – it may
take several times.
