You have to be fairly careful when acid washing this sort of thing as acid eats the cement that holds the pebbles in place as well as the stuff you are trying to get of the surface. do a test spot and see what happens, or better still have a talk with a pool builder about it.

yes it is an acid
no it is neutral
Washing powder doesn't contain acids.
Yes, it is. You can tell weather something is an Alkali, Neutral pr acid via the pH scale or, you can tell if something is an alkali from its consistency; if it is sludgy (like washing-up liquid), it is an alkali. So, I am under the influence that washing-up POWDER is too, an alkali.J.S.P. Aged 11
It is a base.
It's an acid
First, what are you acid washing? Most surfaces require the acid be neutralized with a TSP prior to adding any sealants or primers.
it is not an acid because it doesn't mixed with the soloutions! <3
I believe it is a base.
The pH of the solution become 11-12.
