I'm on a similar problem after grouting shower tiles with a 'cement' style grout. Now the ceramic tray is blotched with residue.. Scraping sort of works, but I don't want to scrape the top off the surface !

Is there some sort of "solvent" for cement/lime mortar type products? The building trade must come across this a lot.. ?

 

[Symptoms]

Brick cleaner (sometimes known as mortar cleaner/remover). Brush it on, wash it off. It's a weakish hydrochrolic acid solution and is the 'dogs b*llocks' for all this type of work. It's great for cleaning all 'lime' type stuff off just about everything - we use it to refresh bathrooms; WC pans, basins & baths come-up looking like new. Cleans the limescale off taps, wastes, shower trays, etc. so they come-up sparkling. Just watch the reaction as the cement/limescale bubbles loose. If needs be a brush to agitate sometimes helps but be ready to wash-off (neutralise) with water when done. Stainless steel will mark so don't use it there. Won't work on non-cement tile adhesives/grouts.

Wear gloves & goggles and don't let it splash on your clothes, otherwise it's fine to use.

ps. I even use the stuff to de-scale my kettle - fantastic!

Sounds just like the trick for me, but I'd do a test before applying it on PVC!

Careful with the acid..
One tip you could try is to wait for a cold day/night and soak the area with hot water, cement should just fall off with a few stubborn wipe overs.
Whenever i was asked to re-polish upvc due to dry cement 99 times out of 100 this method worked, As the upvc is smooth the adhesion should be minimal.
