do you think this will work on mortared stone wall ?

This was very impressive

Fake.Not working

Thank you Sir!

Thank you for this video.

Your tip using lemon juice really helped me out with brick mortar haze clean up on my chimney. My bricks are a very rough texture, so I need to repeat the lemon juice method about 3 times, with wire brushing in between, but it works well. I didn't want to do the acid method. Thanks again.

I'm going down to the shop and get this. This could be BIG!

super helpful thanks!

I just tried. It didn't work for me.

A total bust. I tried it on pavers. Didnt do a thing. 😢

How old is the staining 10 years old? Or two days?

Thanks for thé tip!!!!

mortar is a combination of sand, cement, and lime. The staining is from the lime. Lime is a base. You can clean lime stains with any acid. Just as long as it's clear since you don't want to stain it with something else. Sprite, lemon juice, seltzer, baking soda, vinegar all work to some degree. BUY whatever is cheapest.

What a superb tip .... thanks for taking the time to show us .... Chris in the UK

Had to Do an emergency brick step repair today 50 degrees so will take a while to dry…likely be back to winter cold here in cny sunday…i got residual all over otherwise mortar would turn to soup and never set in the cold…so am I screwed? Or just need a ton of lemon juice/vinegar come spring? Prefer not to use real strong acid

Seems like a good job for citric acid powder. I always keep a big bag around. You can mix it to whatever strength you want and use it anywhere you’d use lemon juice or vinegar for cleaning. A bag of a few pounds is the equivalent of dozens of jugs of vinegar or similar, but much cheaper and obviously easier to store. You can also use it for cooking - it’s the same powdery stuff you find on sour skittles and gummis!

Wow!!! Not surprised because lemon juice is acidic!

show it DRY. ITS STILL WET

This totally worked. Remodeling my kitchen that had the chimney run through it but was covered in Plaster AND mortar. Just using water, brush and sponge was not working. Thanks for posting!

This worked like a charm! Thank you for sharing!

Thank you for the video

I repointed my brickwork. Left it to dry a few days. I tried this and it smeared the cement all over the brick. What did I do wrong?

Thank you!!!!

Brilliant! I’m gonna try this

Will this work on those white patches on red brick? I think they're hard water stains

Now that worked great! Thanks

Think that will stain my roof shingles on the rinse off after cleaning up my chimney stack?

I started this mid-video and thought you were peeing on the bricks

Thanks it worked

Just tried this on June 7th and it works just great...thanks for the tip and for saving me some money.

Thank you you I have hope now.

Now this was the exact video I needed, didn't think of lemon juice!!! Off to the shop :) :)

What does it look like after it dries. Wet brick hides efflorescence

Will those work on mortan stain?

Thank you so much 😊

You just saved my job!!!

Repointing my house now. This works remarkably well. Thanks!

What about vinegar?

What can you use after to protect the brick from it happening again. Or is this something you have to keep doing

If it bubbles it means it's lime mortar otherwise its portland so may not be effective for that but I'll try it. This isn't proper tuck pointing, but for some reason in the US you guys call it that

Worked like a charm. Thanks.

This actually works! Thanks so much for this tip! I was trying to find ways not to harm my flowers and bushes. Thank you so much, you’re amazing!

citric acid works well... better and cheaper if you buy the pure stuff but don't smell as good. :D

learnup on sealing

What about white vinegar?

Thanks for the great tip. I did some stucco work and ended up having the white film of concrete on my bricks. I got a gallon of lemon juice, poured it on the affected areas, brushed, swept, then washed the area. Wow. Like magic.

Excellent. Going to try it out on my sidewalk I repaired with new brick. Thanks for the tip!

*Guuuuud...*

If that bottles not in the video, I'd say he's 100% peeing

Does vinegar work as well?
