Mastic on my sisters tub, HELP please?

Hey everyone;
My little sister is in the process of remodeling one of her bathrooms and had someone come in a lay the tile for her. Problem is he slopped mastic all over the place and now she has to clean it up.
I have attached two picks of the tub and one from the tub box. The tub is acrylic so she is concerned about damaging the finish when she is getting the mastic off.
Any and all suggestions would be appreciated.
She has assess to this link, so she can answer any questions that might come up.
Thanks in advance for your help, you guys have been great for me over the years.
Take care
Dan in Albuquerque

So you're saying the tiles were installed with mastic instead of thinset?

Please tell me she hasn't paid the bill yet....

That doesn't look like mastic...... looks like thinset mortar.
That's an acrylic tub and should have been covered to prevent scratching.

If that is thinset like it looks like..... it needs to be wet..... and NOW.

How drunk was he? She needs to get him back to clean up his mess. If not and water isn't enough she might try vinegar. I've see it recommended for cleaning grout off tile. If clean up damages the tub then he owes her a new tub and cost of installation.

Try Coca-cola. Not kidding. Whatever you do, don't rub it with a rag or scrape at it with anything steel. The plastic putty knives are good but you still can't rub the grit around. Be careful!

Thanks

Hey everyone.

Yes, you are correct, it is not mastic, that was/is my error.

Getting her money back , well that is not so easy as it was our brother that did the work for her.
She did in fact have it covered, so that only complicates matters even more.:wa
I will let you know how things work out.
Take care everyone.

Thank you everyone! This is Dan's sister. I confirmed that the goop all over the tub was mastik. I soaked rags in boiling hot water and repeatedly laid them on the mastik spots until they softened enough to be gently removed with a plastic scraper and a cloth. It was a slow process, but the tub is clean and scratch free. Thank goodness!

Unfortunately, your issues are deeper than splotches on the tub. Mastic is not approved for use in a shower for the exact reason you were able to clean the tub. It softens in the presence of heat and moisture.

At that, I wonder what else about this tile install was not properly researched? What was used under the tile?

The tile symmetry tells me he has done tile before. I, too, am concerned about what was used as a substrate, and hopefully it wasn't greenboard.

Not sure if symmetry tells enough most anyone can start in the middle. Also having the tub spout and service handle hit perfectly on a grout line and/or center tile would have shown more skill. Those subway tiles have built in spacers so installation is quick. There was an awful lot of slop left on the tile faces. Anyone who knows, understands that it is easier to clean as you go then let things harden on the tile surface. The simple lack of masking of a brand new tub also gives me pause.

Thanks everyone, and I love the humor.

Answer, no he is not doing my bathroom next.
Yes it does say how easy on the box to clean up... when it is wet not dried for a week or more.
Family is family.. Most of the time is great, sometimes shi* like this happens.

Take care
