Is Rob Parkers Best Algae Remover safe to use around pets and plants?

Is Rob Parkers Best Algae Remover safe to use around pets and plants?

We often get asked if Rob Parkers Best Algae Remover is safe to use near plants and pets. 

This is a question we are increasingly asked as the product is becoming more widely known for its success at renovating green areas of patios. 

Always use Rob Parkers Best products in accordance with instructions given

When using any of our Rob Parkers Best products, always follow the instructions given on the packaging closely. We also have further information for the safe and effective use of our products available online.  This may be the Technical Data Sheet or the MSDS given for each product. Plus for some products, including Rob Parkers Best Algae Remover, we have also produced a video to help users visualise the instructions given for best most effective use. 

Rob Parkers Best Algae Remover is supplied to you in a concentrated format.  This is to be diluted by the user in 8 litres of water.  The reason we supply in a concentrated format (250ml) is to enable us to reduce plastic packaging.  Plus, we have calculated that for most households, the amount supplied will provide sufficient (diluted) dosage to clean one patio, therefore removing the need to store, or dispose of extra unused product. 

 Instructions and advice on how to use Rob Parkers Best products may be available in several different places.  

We give comprehensive advice on the packaging regarding the safe use of this product. The MSDS supplied for this product refers to the undiluted format. In its neat format, it is harmful if swallowed, and skin should be protected during application.   

It therefore follows that pets should be kept away from areas that are being treated whilst wet product is in use, in case of accidental spillage by the user.  We also advise that plants should be protected and not sprayed with the solution.   

However, once heavily diluted with water as per the label and TDS instructions the product does only what it is formulated to do, that is, it is absorbed into organic vegetation and in time causes the growth to die. 

Rob Parkers Best Algae Remover is safe around all plants and animals after the treated area is dry.

Surfaces treated in accordance with the label and TDS will dry and no animal, whether pets, frogs, toads, snakes, bats, hedgehogs etc will be harmed in any way from ‘licking’ such treated surfaces. The product is biodegradable and there are no issues either for runoff into the guttering and drainage system. 

The product has long been used not only for patios, but also Tennis Courts, Roofs and Garden Furniture and there has never been an issue and the product is perfectly suitable for all these surfaces where wild animals and pets are likely to roam. 

As with all household products care should be taken to ensure humans, animals and plants are not unnecessarily exposed to chemicals that could cause harm if inappropriately consumed.  Therefore, the user must at all times be aware of their workspace and the people, animals and plants for whom they are responsible, during application of products.

How to remove paint from stone paving

How to clean paint stains from stone paving?

Some home maintenance jobs can create a mess, and it can seem like never ending work is being created whilst trying to improve the home!
A typical example is exterior house painting. However careful the painter is, odd spots of paint can become stuck to adjacent paving and pathways.
Painting gates is another fiddly job, where paint applied to vertical surfaces will drip down onto driveways and paths, where if left it will dry and become very difficult to remove.
In more severe cases, a lot of paint can be spilt! Whoops! What can be used to remove this paint?

Don’t use brick acid!

Don’t use brick acid! This very harsh product seems to be the building trade go to product for clearing up a mess, but we strongly advise against this course of action.
Brick acid is an extremely harsh acid that works by dissolving the top layer of the stone to which it is applied. This can in some cases cause irreparable damage to the stone.

Use Rob Parkers Best Stone Stripper to remove paint & varnish stains from stone

Our advice is to use Rob Parker’s Best Stone Stripper. This is a gentle formulation that will dissolve multiple layers of paint, varnish and sealants from stone surfaces without causing damage to the stone.
This product needs to be applied generously to the affected area, and left for up to 24 hours before scraping and rinsing clean. Up to 5 layers of paint can be removed with a single application.

How do I remove rust marks from my patio?

How do I remove rust marks from my patio?

Remove rust marks and stains easily.  Follow this advice.

Rust marks can appear on a patio for various reasons, and can prove tricky to remove.

Rust marks can stain a patio where metal furniture has been placed onto a stone patio.

If you employ a lawn maintenance company they may spread fertiliser around your patio and path area.  These products can contain iron, and when mixed with water and air they become iron oxide. Again, this will create rust marks on top of the stone surfaces such as patios and pathways.

Oxide deposits can also be released from within stone paving if your contractor uses brick acid (nb. please don’t do this- Conclear is safer) to clean up after installing a stone patio. This will appear as brown rusty coloured stains on the surface of your paving, especially on Kandla Grey Sandstone, which is particularly affected.

Many of our customers have had this problem, and come to us with what they think is a ruined patio. Cement spills are often aggressively treated with brick acid after installation by contractors.  We don’t recommend this.  Conclear is our safer and ecological cement remover.  However, it is possible to remove rust marks and stains caused by brick acid use with Rob Parkers Best Rust Remover.

Rob Parkers Rust Remover can solve the problem in all these instances.

Rob Parkers Best Rust Remover is easy to apply.  Use a paint brush to apply the product to the affected spots and watch the rust disappear.  Rinse the area with water once the rust has disappeared. When the area is dry Stoneworld recommend sealing the stone to prevent rust stains from occurring again.
