Caustic soda to remove ingrained dirt on tiles?

Hello

I am hoping to fix new 'beading' (1" strip of pine wood) along a length of skirting board.

At the moment, there is no beading there - just a small gap between the skirting board and tiled floor - but there is a strip of what could be old glue on the tiled floor where beading used to be before I moved in here. It just looks like a 1" strip of dirt on the tiled floor and no amount of mopping with bleach with remove it - I need to remove it before I fix the new beading into place.

Would the best way of removing it be to use caustic soda applied with a scrubbing-brush?

Many thanks.

Are you in the US?
Guessing you mean baseboard not skirting board, and 1/4 round not beading.
Got a picture?
My oscillating saw would make quick work of it.

Well, it is not beading, but inside corner molding, commonly used vertically in room corners where poor paneling cuts are hidden. I guess you could use it for shoe molding, but as I said, it isn't common there. Using a plastic putty knife and a good cleaner, such as Purple Power or what ever is available in the UK, would loosen it up. Of course you didn't post a picture of the build up, so we don't know what you have. Once you clean it, replace what you have as shoe molding with quarter round which has a dimension of 3/4" x 3/4" and should re-hide it. Alexandria Moulding WM 105 3/4 in. x 3/4 in. x 96 in.

A pic or two of what needs cleaning would be helpful so we can see the dirt and get a better idea of what needs to be done to clean it.

Joe Caption, I'm curious how you would remove glue and dirt with a saw?

I'll say it is probably caulking from the previous install which would not just wipe off without scraping. A razor scrapper would assist in removing the line. Or, if installing additional moldng, it would pretty much cover it self up.

This is an example of it:

I could try a paint-scraper, yet, but no caustic soda?

It has a kind of 'sandy' or 'gritty' feel to it.

Thanks.

Thanks, Chandler.

I can order Purple Power from eBay, but the postage is a little high:

I will have a look for a local equivalent.

Thanks.

Sorta looks to me like some stuck foam backing from a previous carpet?

That's a thought, yes. I will see if I can get rid of it this week.

Thanks for your reply.

Try scraping it with a putty knife using soap/detergent as a lubricant.

One picture you are showing hardwood flooring, and in another you are showing VCT, so it is somewhat confusing as to what you are trying to clean. Ebay saw you coming.....here's what we normally pay for 2.5 gallons at a box store Purple Power 2.5 gal. Cleaner/Degreaser-4322P - The Home Depot

Larry, the hardwood pics were just an example of the molding being referred to. Post #8 is what actually needs to be cleaned.
