128 oz. 30% Vinegar All Purpose Cleaner Concentrate

Yes, it will kill weeds. I dilute it to a 20% concentration and it works very well and much faster than Roundup. However, it does not do a great job of killing the roots, so you may have to spray again. I find I have best results when on warm days, however I have also used it at 50 degrees F. with good results.

This is a LOT stronger than regular vinegar.

Harris does not have information on this use. You would want to consider what material the drip pan is made of. Also, there are no claims on the product label as far as killing mold or disinfecting. Thank you. P.F. Harris

It will kill both if used near or on both.

Not sure. Why don't you use a drain clog remover product instead? Drain clog removers are at a very basic pH whereas this product is acidic.

I would not risk using this on that application. Might eat your polymer seals and hoses.

The main component in vinegar (acetic acid) is known to kill mold. I think this 30% CLEANING VINEGAR would be good to use on surfaces that may be destroyed by bleach. Wherever you use either of these, make sure you do a spot test in an inconspicuous place.

Yes, you need to dilute the concentrate- 3 parts vinegar with 7 parts water for removal of mold and mildew.

I would use regular household vinegar for this. The 30% is 5x more concentrated. The rule for using household vinegar is to add 3 cups of water then 1 cup of household vinegar to a wash bottle and the spray(1.5%) thoroughly rinse in 30 sec. You can still use this 30% stock. You would wear gloves and a eyemask and take around two tablespoons of the 30% and then dilute to 4 cups water

Ummmm.....you’ll really really reeeeeek of vinegar! And this is very toxic. I think regular detergent will deactivate corona virus, like sudsy hand washing will.
