can I use the 30 second cleaner on my shower walls

I would NOT use it in the house as it's designed to be used outdoors. Thus the name - outdoor cleaner.

So is this 4 gallons 4 quarts

Thanks for your question! This is for 4 bottles of 1 gallon each. So you will receive 4 gallons total.

Can this be used on a sealed flagstone pool patio?

I used it for my house. And it worked well. I’m sure it’ll do wonders for the patio as well

I sprayed over this thing on the roof. it did clean, although i had to brush off moss. however, it is showing yello after application. is it expected?

To kill moss on your roof shingles mix 1 gallon of bleach, 1 gallon of water, & 1 cup of dawn dishwashing detergent. Spray it on and let it sit with no chance of rain. Shingle manufactures recommend it. I’m sorry I don’t know about the yellowing.
