My situation: I have some masking tape adhesive to remove from the decorative brick/tile that is between the concrete deck & the water (from a perimeter caulking job so the entire length of the pool).
I’ve tested various items & know Softscrub will do the job nicely. I’ll have a garden hose to wash it onto the deck & away from the water but some will get in the water.
I remember as a kid I’d see them cleaning the tiles IN THE WATER with Ajax (so I’m guessing Ajax is ok).
I haven’t tested Ajax but it’s bound to remove the adhesive too, but it is probably more abrasive than Softscrub & I suppose could scratch the decorative brick/tile so I’d rather go with Softscrub. Is there a good reason to use Ajax instead of Softscrub? Normally I wouldn’t ask such a petty question but I’ve had enough this season with undesirable chemicals in the water. If the deck-tile interface was ideal (sloping away from the water, tile higher than deck) I wouldn’t even ask because I’d be confident it would all wash away, but that isn’t true.
