I mean, every market has 2 or 3 whole aisles dedicated entirely to cleaning products and each seems specific for one thing only. I feel like some soap with a disinfectant is enough, but most people I know do a whole 3 stage cleaning ritual - soap (and rinse), disinfectant (and rinse), bleach (and rinse to finish)
Fabuloso mixed at 1 Oz per gallon of water. Great for getting the scum off the tub, cleans everything but glass. It’s cheap as hell.
Vinegar & water for glass cleaner (with a drop of dish soap). Cleans better than store bought.
Occasionally I’ll use a specific toilet bowl cleaner when minerals start building up. I get the bottle that squirts up under the rim because that’s where mineral buildup starts.
But really, just about any light cleaner works for a bathroom, I’ve used everything. Just don’t use abrasives until you know exactly what you have for materials. Many baths are plastics these days, which are easily scratched by abrasives.
What’s that fabuloso?
It’s a general purpose cleaner that’s sold in jugs that are way too similar to a fruit juice jug for my liking. Works great, cheap, smells good.
